Title: Computing centre module and method

Description:
Various embodiments relate to a computing center module and method. 
     To accommodate continued growth, container computing centers have become popular in recent years, where the individual components of a computing center are arranged in a transportable container. Such containers may be prefabricated and preinstalled by manufacturers ex works, thus enabling efficient modular construction of larger computing centers at any given location. 
     Traditionally, the container computing center is built on site, assembled, and its components are subsequently wired together. When the components are assembled and wired, attention is often paid to the reliability of the entire container computing center, as reliability may be critical to a variety of services that the container computing center may provide. Therefore, testing of actual reliability is not performed until the container computing center as a whole is fully constructed and operational. The result of the test is subsequently classified and certified to the container computing center (also referred to as computing center certification). However, changes to the container computing center may require a new computing center certification under certain circumstances. 
     According to various embodiments, it has been illustratively recognized that computing center certification enables logistically independent components of the container computing center to be arranged within a container and to be individually pre-certified for each container (also referred to as pre-certification). In other words, the container containing the component may be individually reliability tested in terms of its physical structure and thus receive pre-certification before the computing center is fully constructed or before the container is even transported to its final location. 
     According to various embodiments, a plurality of individually pre-certified containers are provided that are assembled into a computing center module without impacting their pre-certification. Thus, it is possible to put the individually pre-certified containers into operation as quickly as possible and with a high degree of reliability. For example, the use of the individually pre-certified containers may accelerate and/or simplify (e.g., make cheaper) the construction of the computing center or its computing center certification and thus meet the increasing demand for shortened times from planning to commissioning. 
     Different availability classes 1 to 4 require certain arrangements and duplications (redundancies) of typical components and supply paths of the trades electricity, network or Internet for the media supply and cooling as waste heat disposal. In addition, there are also structural requirements (e.g., requirements for resistance class against burglary for doors or fire and smoke protection requirements, space requirements for maintenance and installation) for each availability class. The availability classes are assigned average expected availabilities of the IT components (information technology components) in percent per operating year. 
     With a computing center or development for availability class 3, availability classes 2 or 1 may also be met by omitting or not using components. 
     It becomes clear that cost advantages may be achieved with a development of a flexible module platform that aims for the highest possible availability and that covers as many use cases as possible, and that the idea and the associated intellectual work must be protected from imitation in order to be able to transfer it to series production. 
     According to various embodiments, a configuration is provided for the computing center module or method that does not provide any internals in the container walls and doors, and provides media supply and removal and air openings and an access and entry door only via a double wall behind the container door at the front end. This is because it provides simplified international transport and burglary protection, but more importantly it also provides a 3-sided scaling option in the x, y and z directions. 
     Illustratively, each individually pre-certified container is provided such that its coupling to the rest of the computing center does not require any modifications to those components of the container that meet the pre-certification requirements. Thus, each individually pre-certified container may be added to the computing center “as is,” possibly relocated within it, or removed from the computing center (e.g., for replacement) without affecting the computing center&#39;s computing center certification. Further, scalability to larger computing centers may be done on a module-by-module basis and international transport of containers may be simplified. 
     For example, several individually pre-certified containers (e.g., so-called 20 ft containers) of the same design, which are set up symmetrically with respect to each other, may be used to set up a grouping (e.g., with 1.0 megawatt or more), which serves as a computing center module and is optionally horizontally and/or vertically scalable. Instead of two symmetrically configured containers, a larger container (e.g. a so-called 40 ft container) may also be used, which has two symmetrically configured segments. 
     According to various embodiments, a computing center module may comprise: a plurality of containers, wherein each container comprises a plurality of side walls that are substantially fully openable; a computing device within the container, wherein the computing device comprises a plurality of processors; a power infrastructure within the container for providing electrical power to the computing device; and wherein the power infrastructure of each container of the computing center module is individually pre-certified with respect to reliability of the computing device.

     In the following detailed description, reference is made to the accompanying drawings which form part thereof and in which are shown, for illustrative purposes, specific embodiments in which the invention may be practiced. In this regard, directional terminology such as “top”, “bottom”, “front”, “rear”, “forwards”, “rearwards”, etc. is used with reference to the orientation of the figure(s) described. Since components of embodiments may be positioned in a number of different orientations, the directional terminology is for illustrative purposes and is not limiting in any way. It is understood that other embodiments may be used and structural or logical changes may be made without departing from the scope of protection of the present invention. It is understood that the features of the various exemplary embodiments described herein may be combined, unless otherwise specifically indicated. Therefore, the following detailed description is not to be construed in a limiting sense, and the scope of protection of the present invention is defined by the appended claims. 
     In the context of this description, the terms “connected”, “attached” as well as “coupled” are used to describe both a direct and an indirect connection (e.g. ohmic and/or electrically conductive, e.g. an electrically conductive connection), a direct or indirect attachment as well as a direct or indirect coupling. In the figures, identical or similar elements are given identical reference signs where appropriate. 
     According to various embodiments, the term “coupled” or “coupling” may be understood in the sense of a (e.g. mechanical, hydrostatic, thermal and/or electrical, but also data), e.g. direct or indirect, connection to an interaction chain. For example, multiple coupled elements may interact with each other along the interaction chain (e.g., communicatively) so that a medium (e.g., an information, energy, and/or matter) may be exchanged between them. For example, two coupled elements may exchange an interaction with each other, e.g., a mechanical, hydrostatic, thermal, and/or electrical interaction, but also a data interaction. According to various embodiments, “coupled” may be understood in the sense of a mechanical (e.g., physical or physical) coupling, e.g., by means of a direct physical contact. A coupling may be arranged to transmit a mechanical interaction (e.g., force, torque, etc.). 
     According to various embodiments, an ISO container (e.g., a 20 ft container) with three openable side walls (also referred to as loose walls), a so-called “3-side door container”, is provided as a transport unit and assembly module. The outer shell of the ISO container may be unchanged (i.e., for example, there are no connections on the outer walls of the container on at least two or three sides), so that it retains its CSC certification (COC—“Convention for Safe Containers”), and is thus internationally transportable and additionally inconspicuous (e.g., does not suggest any conclusions about its contents). This is achieved, for example, by means of several partitions (e.g. inner walls) at the two ends of the container, which are arranged behind the loose walls (e.g. having hinged doors) and carry a security door with access control and also flange connections. For example, two 20 ft containers (20-foot containers) may be joined together at their ends to form a pair of containers of the first type, thus forming a 40-foot (approximately 12.2-meter) long unit. Two 20 ft containers may alternatively or additionally be joined together at their long sides to form a pair of second type containers, thus forming a common center aisle. For example, two pairs of containers of the same type may be joined together in this way to form a space-saving and functional grouping. The containers of each container pair may be arranged mirrored to each other. However, other containers, e.g. 40-ft containers or non-ISO containers, may also be used. 
     In this way, contiguous computing center modules, e.g., with an electrical power of 1 MW (megawatt) or more, may be provided, having, for example, one or more than one container pair (e.g., of the same type). Optionally, vertical scaling may be achieved by stacking multiple computing center modules. 
     Various embodiments provide a container that may be equipped, for example, with a computing device (e.g., comprising a computer, server or several processor racks) for the modular construction of a high-performance computing center. One effect of the container form is that a computing center formed from such containers may be expanded in a modular manner, and that, for example, each individual container may be prefabricated ex works by the manufacturer and pre-certified with respect to a reliability of the computing equipment. 
     One effect of pre-certification is that the containers no longer need to be certified after they have been transported to the computing center site. This makes it possible to put the computing center into operation at the destination more quickly and with less effort. 
     The or each container (e.g. an ISO container) may, for example, be designed in accordance with ISO Standard 668. This has the effect that, in this regard, transport of the container on ships, railroads and trucks is standardized and thus easily possible. In various embodiments, the container may have an outer length of 13,716 m (45 ft), 12,192 m (40 ft, e.g. as a standard container or sea container), 9,125 m (30 ft), 6,058 m (20 ft, e.g. as a standard container or sea container), 2.991 m (10 ft), 2.438 m (8 ft) or m 1.968 (6 ft), have an outer height of 2.591 m (e.g. as a standard container) or 2.896 m (also referred to as a high-cube container), and an outer width of 2.438 m. For example, a so-called 20 ft container has an outer length of 6,058 m, an outer height of 2,591 m, and an outer width of 2,438 m. A so-called 40 ft container (e.g., 40 ft HC container) has an outer length of 12,192 m, an outer height of 2.896 m, and an outer width of 2,438 m. In one example, the container may have an outer dimension (length×width×height) of 6.058 m×2.438 m×2.896 m. The container may have an inner dimension (length×width×height of the interior) of 5.853 m×2.342 m×2.697 m. 
     In one embodiment, each substantially fully openable side wall (also referred to as a loose wall) of the container is formed as a multi-winged, foldable or demountable wall. Alternatively or additionally, the loose wall may be configured to be resealable in accordance with ISO standard 668, and/or the container may be indistinguishable from other containers. Thus, in this embodiment, shipping of the container by common carriers and shipping routes may be facilitated in a simple manner by means of trucks, trains, and ships. The or each loose wall may, for example, have wall elements positively connected to a housing of the container or formed therefrom, for example by means of a bearing, connected by means of pins and/or screws. 
     The computing facility of the or each container includes one or more than one computing unit, for example, arranged to accommodate a plurality of processors and/or storage media in a high-density manner. These may include processors, for example, server processors (CPUs), graphics card processors (GPUs), cryptoprocessors, ASICs, FPGAs, TPU (tensor processing unit), or mining hardware for cryptocurrencies. Storage media may be mechanical hard disk drives (HDDs) or solid state drives (SSDs). 
     In various embodiments, the container may include a plurality of supply paths with a feed interface configured to supply at least one medium to the container from outside (e.g., by means of coupling an uninterruptible power supply to the feed interface). The medium may be, for example, a temperature-controlled fluid (also referred to as a temperature-control fluid, e.g., cooling water), electrical power, and/or a communication signal (e.g., a network signal). Each supply path may be arranged to functionally interact with the computing device and pass the respective supplied fluid to the computing device. The set of supply and disposal paths within the container may also be referred to herein as infrastructure. Depending on the type of medium (temperature control fluid, electrical power, and/or communications signal), the infrastructure may be referred to as temperature control infrastructure, power supply infrastructure (e.g., power supply infrastructure), or telecommunications infrastructure. For example, the temperature control infrastructure may be arranged to extract thermal energy from the computing device along the supply path. Optionally, supply-critical supply paths or components of the container may be redundant. 
     Redundancy refers to the presence of functionally identical or comparable resources in a technical system, not all of which are normally required for failure-free operation. Functional redundancy may mean that the supply paths required for operation are designed several times in parallel so that, in the event of failure of one supply path or in the event of maintenance, another supply path ensures uninterrupted operation. Optionally, the mutually redundant supply paths may be spatially separated from each other, e.g. by protective walls and/or spatial separation (e.g. by arranging them on opposite sides of the container) to ensure further safety. 
     Redundancy of an element used to operate the computing system (e.g., a supply path, a component thereof, or a processor) may be understood herein to mean, for example, that at least one functionally identical or comparable copy of the element is present, and the element and its copy are also set up in such a way that it is possible to switch between them, e.g., without having to interrupt the operation of the computing system. The element and its copy may then be set up to be mutually redundant (also referred to as a mutually redundant pair). 
     Switching between two mutually redundant elements (e.g. from a first supply path to a supply path that is redundant to it) may be automated, for example, if a malfunction has been detected in the active element. The malfunction may be detected as critical, for example, meaning that it could lead to a failure or partial failure of the computing system. The switching may be performed, for example, by means of a transfer switch, e.g., automated. The pre-certification may require, for example, that the container has an at least partially redundant infrastructure. Alternatively or additionally, e.g., if a container as part of a computing center itself has only some of the typical computing center components (e.g., the transformers, generators, and uninterruptible power supply (UPS) may be centralized and/or located outside of it), the redundant components and supply paths may meet at least some of the requirements for pre-certification (e.g., the container may have two redundant electrical subdistributions and two supply paths), so that pre-certification in principle certifies expected availability, if outside of the container, it also meets the requirements (e.g., Classified as “supports availability class x,” where x=1, 2, 3, or 4). 
     According to various embodiments, the redundancy may be N+1 redundancy. An N+1 redundancy denotes that the computing device requires a maximum of (e.g., exactly) N supply paths for operation, with at least N+1 supply paths being present in the container. The N+1th supply path may be set up as a passive standby supply path. If one of the N supply paths fails or needs maintenance, its function may be taken over by the N+1th supply path, e.g. without having to interrupt the operation of the computing system. If two of the N supply paths fail, this may result in a failure or partial failure of the computing system (corresponding, for example, to availability class “VK 3” according to DIN EN 50600 or “Tier 3” according to the North American standard of the Uptime Institute). This could be counteracted by using a higher redundancy, e.g. by designing the redundancy as parallel redundancy. In parallel redundancy, at least 2·N supply paths are available, e.g. 2·(N+1) supply paths (corresponding, for example, to availability class “VK 4” according to DIN EN 50600 or “Tier 4” according to the North American standard of the Uptime Institute). 
     Single-path supply paths without duplication of components, on the other hand, may comply with “VK 1” or “Tier 1”, whereby in addition to the availability classes, further construction requirements (e.g. burglary protection, fire protection, etc.) may be defined in the standards. The computing center module may, for example, be built according to “VK 3” or “Tier 3” standard. A “VK 4” or “Tier 4” standard may be more complex in its fulfillment (e.g. suitable for critical infrastructures, as required for energy supply companies, for example). 
       FIG. 1  illustrates a method  100  according to various embodiments in a schematic flowchart for handling a plurality of containers  102 . Each container  102  may include a housing  1102   g , which may include contiguous (e.g., four) side walls, a ceiling, and a floor surrounding an interior of the container. Further, the housing  1102   g  may include a supporting housing structure (e.g., a frame or framework) to which the plurality of side walls, ceiling, and floor are attached. Of the side walls of the container  102 , a plurality of side walls  102   s  are substantially fully openable (also referred to as loose walls  102   s ). For example, each loose wall  102   s  may include at least one (i.e., exactly one or more than one) wall member that may be opened, e.g., by being demountable, movable, or positively supported (e.g., by hinges). The remainder of the loose wall  102   s , e.g., the bearing and/or the frame, may be, for example, materially bonded (e.g., welded) to or part of the housing structure. For example, the at least one wall member of each loose wall  102   s  may be adapted to be opened and/or reclosed in a non-destructive manner. For example, each loose wall  102   s  may be closed by means of a closure device (e.g., a closure latch or lock). 
     A substantially fully openable loose wall  102   s  may be understood to mean that, on the housing side of the container  102  on which the loose wall  102   s  is disposed, substantially all of the interior of the container may be or may become exposed. For example, the interior of the container  102  may have a height  102   h , wherein an opening  102   o  provided by means of the opened loose wall  102   s  exposes at least 80% (e.g., 90%) of the height  102   h . Alternatively or additionally, the opening  102   o  may expose at least 80%, (e.g., 90%) of a length  102   b  or width of the interior (cf. the interior dimension). The housing structure may optionally segment the opening  102   o . For example, at least about 75% (e.g., 80%, 90%, or 95%) of the loose wall  102   s  relative to an area may comprise the opening  102   o , which may be covered by means of the at least one wall member. 
     The container  102  may have a computing device  104  therein that includes a plurality (e.g., at least 10, at least 100, or at least 1000) of processors. The container  102  may further include, in its interior, an infrastructure  106  for supplying power to the computing device  104  (also referred to as power supply infrastructure or power infrastructure). The power supply infrastructure  106  of each container  102  may be individually pre-certified  110  with respect to reliability of the computing device  104 . Optionally, multiple infrastructures or the entire container may be pre-certified as part of a computing center or the container may be pre-certified with additional technology containers. The container with the pre-certified power infrastructure  106  will also be referred to herein as a pre-certified container  102  (FOC or, more simply, a container). 
     The pre-certification  110  may illustratively represent how high the reliability of the computing device is. For example, the reliability (also referred to as availability) may be greater than 95%, e.g., at least about 98.97%, e.g., at least about 99%, e.g., at least about 99.9% (also referred to as high reliability), e.g., at least about 99.99% (also referred to as very high reliability), e.g., at least about 99.999%. The reliability may be or become classified, i.e., divided into classes (also referred to as availability class), depending on the certification type. 
     For example, a pre-certification according to DIN EN 50600 (of 2013, e.g. DIN EN 50600-1 of 2013, or DIN EN 50600-2-2 of 2014, or DIN EN 50600-2-3 of 2015) may specify that the reliability of at least about 98.97% is classified as availability class 1, the reliability of at least about 99.9% is classified as availability class 2, the reliability of at least about 99.99% is classified as availability class 3, or the reliability of at least about 99.999% is classified as availability class 4. 
     For example, a pre-certification according to U.S. Tier Classification (e.g. of 2015) may indicate that reliability of at least about 99.671% is classified as Availability Class 1 (also referred to as Tier 1), reliability of at least about 99.749% is classified as Availability Class 2 (also referred to as Tier 2), reliability of at least about 99.982% is classified as Availability Class 3 (also referred to as Tier 3), or reliability of at least about 99.995% is classified as Availability Class 4 (also referred to as Tier 4). 
     However, other (e.g. commercial) certification types may also be used, e.g. a Bitcom certification (e.g. according to Bitcom guide 2013) or an InfraOpt certification (from 2017). 
     Depending on the certification type or availability class, various pre-certification requirements may be met, as described in more detail later, for example, at least N+1 redundancy (or 2·N redundancy) of the power supply infrastructure  106 . The pre-certification  110  described herein (with respect to reliability) is to be distinguished from other certification types, in particular those certification types that certify compliance with protection requirements (e.g., CE/ETSI or SEMKO). Such protection requirements may relate, for example, to the protection of the environment, the protection of the user (e.g. his integrity), protection against tampering or data protection and may, for example, be prescribed by law. 
     The method  100  may have in  101 : Providing multiple FOC  102 . The providing  101  may optionally comprise in  103 : Relocating the plurality of FOC  102 , e.g., to land, sea, and/or air. The method  100  may include in  103 : Arranging the plurality of FOC  102  relative to each other such that any two FOC  102  of the plurality of FOC  102  are arranged immediately adjacent to each other. For example, they may be arranged with at least two (e.g., face or longitudinal) loose walls  102   s  facing each other. The method  100  may comprise in  105 : Opening one of the plurality of loose walls  102   s  of the or each FOC  102  facing another FOC  102  of the plurality of FOC  102   s . The FOC  102  may be arranged such that when the loose wall  102   s  is opened, the pre-certification of the FOC  102  (e.g., its power supply infrastructure  106 ) is maintained. To this end, the or each loose wall  102   s  of the FOC  102  may be, for example, free of elements that affect the pre-certification, e.g., that affect the fulfillment of the requirement according to the pre-certification. This may illustratively achieve that no certification of the FOC  102  needs to be performed after connecting the interior of the plurality of FOC  102   s . This accelerates the deployment of the computing center module  151  having the plurality of FOC  102 . 
     The or each FOC  102  may optionally include a temperature control infrastructure (also referred to as a temperature control infrastructure) and/or a telecommunications infrastructure (also referred to as a telecommunications infrastructure). Optionally, the telecommunications infrastructure (e.g., a network infrastructure) and/or temperature control infrastructure of each FOC  102  may also be individually pre-certified  110  with respect to the reliability of the computing device  104 , or the entire container  102  may be pre-certified  110  along with its one or more than one (e.g., different) infrastructures. 
     The FOCs  102  arranged adjacent to each other may provide a computing center module  151 . Multiple computing center modules  151  may be coupled together to form a computing center, for example, by coupling each FOC  102  to an external supply module assembly  202 . 
     The method  100  may comprise in  107 : Coupling the plurality of FOCs  102  to each other and/or to at least one external supply module assembly  202 . The or each supply module assembly  202  may include one or more than one additional module, e.g., optionally a telecommunications module  202   t , a power module  202   z , a temperature control module  202   k  (e.g., cooling module), and/or a gas extinguishing module  202   f.    
     For example, multiple supply module assemblies  202  may be provided, each supply module assembly  202  directly coupled to exactly one FOC  102  or exactly one container pair. Optionally, multiple supply module assembly  202  may be coupled to the same FOC  102  or container pair. 
     For example, the coupling may comprise coupling the telecommunications infrastructure of the FOC  102  to each other and/or to the telecommunications module  202   t , coupling the temperature control infrastructure of the FOC  102  to each other and/or to the temperature control module  202   k , and/or coupling the power supply infrastructure  106  of the FOC  102  to each other and/or to the power module  202   z.    
     In the following, reference may be made more generally to an infrastructure of the FOC  102  for ease of understanding, and what is described for the infrastructure may apply to the power supply infrastructure  106 , the temperature control infrastructure, and/or the telecommunications infrastructure (e.g., by analogy). More generally, coupling of an infrastructure may be accomplished by means of a coupling interface  722  to which the infrastructure has corresponding connections. For example, the infrastructure of an FOC  102  may be coupled to the supply module assembly  202  by means of a feed interface (more generally, a first coupling interface) or to an immediately adjacent FOC  102  by means of a container-to-container interface (more generally, a second coupling interface). 
     For example, the infrastructure (e.g., the telecommunications infrastructure, power supply infrastructure, and/or temperature control infrastructure) may have a plurality of first supply lines that couple the feed interface to the computing device or a terminal device (e.g., a heat exchanger) of the infrastructure. Alternatively or additionally, the infrastructure may have multiple second supply lines coupling the container-to-container interface (CC interface) to the computing device and/or the feed interface. 
     For example, the telecommunications infrastructure has a plurality of network lines coupling the coupling interface to the computing device for connecting the plurality of processors to a local and/or global network (e.g., the Internet). For example, the temperature control infrastructure has a plurality of fluid lines (e.g., pipes for flow and return) coupling the coupling interface(s) to the computing device so that thermal energy may be extracted from the computing device. 
     For example, the supply lines may be arranged in trays (e.g., hanging cable trays) on the ceiling and/or floor of the FOC  102  and spaced from the loose walls  102   s . For example, a raised floor may be used to route the utility cables. The coupling interface(s)  722  may be attached to partition walls, for example, and spaced from the loose walls  102   s . This may be used to ensure that pre-certification is not lost by opening the loose walls  102   s . To provide electrical power for operation of the computing device  104  of the FOC  102 , each (e.g., the first and/or the second) coupling interface  722  may be configured to provide the electrical power or a double thereof, e.g., a power of, for example, more than about 100 kW, than about 150 kW, than about 200 kW, than about 250 kW, or than about 500 kW (kilowatts). 
     In various embodiments, the computing device comprises a plurality of computing units, each computing unit comprising at least one receiving device (e.g., comprising a rack, such as a 19-inch rack or a 21-inch rack) for receiving processors. Such receiving device(s) may be, for example, racks for receiving processor cards and/or entire servers (referred to as “rigs”). The or each computing unit may optionally include a cooling device for cooling the processors (i.e., extracting thermal energy), e.g., a passive cooler and/or a heat exchanger. 
       FIG. 2  illustrates a supply chain  200  according to various embodiments in a schematic supply diagram showing a power flow diagram with various technology attachment containers. A computing center may include one or more than one supply chain  200 , each supply chain  200  of which may include a supply module assembly  202  (e.g., including a supply container and/or technology container, and optionally including an electrical container and/or hydraulic container) and at least one FOC  102  of the computing center module  151 . 
     For example, the supply module assembly  202  may include an airlock module  212  (e.g., a spatially separated airlock). The telecommunications module  202   t  may include, for example, two telecommunications ports  214  that are redundant with respect to each other. Accordingly, the telecommunications infrastructure (also referred to as TK infrastructure) may include at least two redundant telecommunications supply paths, each telecommunications supply path of which may be or may be coupled to one of the telecommunications ports  214 . The telecommunications infrastructure or a telecommunications path may alternatively or additionally be path-redundantly coupled to the telecommunications ports  214  on the opposite side of the container. 
     For example, the power module  202   z  may include a low-voltage main distribution  218  and two uninterruptible power supplies  216  (UPS) coupled thereto and redundant with respect to each other, each UPS  216  of which may be rated at, for example, 250 kW (kilowatts) or more. The low-voltage main distribution  218  may be coupled to a regional interconnected grid  218   v , for example. The power module  202   z  may include, for example, one or more than one power generator  220 , such as an emergency power generator. For example, the power generator  220  may include an internal combustion engine (e.g., diesel engine). The power generator may be powered by, for example, a diesel tank  221  for 72 or 96 hours. Accordingly, the power supply infrastructure  106  may include at least two mutually redundant power supply paths, each power supply path of which may be or may be coupled to one of the UPS  216 . For example, each power supply path may include one or more than one sub-distribution device  106   u  (also referred to as UV), each UV  106   u  of which may be or may become coupled to one of the plurality of UPS  216 . This may provide redundant supplied electrical power, with each supply path being able to compensate for the failure of another supply path. For example, a first UV  106   u  may include a first power line  1061  and a second UV  106   u  may include a second power line  914 , wherein the first and second power lines are arranged to supply power to the same processor. Optionally, the power supply infrastructure may include a base power distribution  106   n  separate from the computing device  104 , which supplies power to components of the FOC  102  not associated with the computing device  104 , for example (e.g., lighting, ventilation, cooling), i.e., illustratively provides a base power supply. 
     The temperature control module  202   k  (here exemplarily arranged together with the energy module  202   z  in a technology container) of the supply module assembly  202  may be arranged to extract thermal energy from the interior of the FOC  102  (e.g., the computing device  104 ), for example by means of a cooling fluid (e.g., a liquid). For example, the temperature control module  202   k  may include one or more heat pumps  222 , which may be set up to be redundant to each other, for example. For example, the temperature control module  202   k  may provide one or more than one cooling circuit  224  (e.g., having different temperature levels of cooling water/hot water and respective supply and return lines) with the FOC  102 . To this end, the temperature control infrastructure  114  of the FOC  102  may include one or more than one fluid line  1141  coupled to one or more than one processor cooler  104   w  of the computing device  104 . The or each processor cooler  104   w  may be configured to extract thermal energy from the processors of the computing device  104  and supply it to the cooling circuit  224 . The resulting hot water may be brought out of the FOC  102  and/or cooled using the heat pumps  222 . 
     For example, the temperature control infrastructure of the FOC  102  may include one or more than one air handler  104   l  (e.g., a recirculating air cooler) coupled to a cooling fluid supply of the cooling circuit  224 . The or each air conditioner  104   l  may be configured to extract thermal energy from (i.e., cool) the air within the FOC  102  and/or supply cooled air to the computing device. At least two fluid lines  1141  and/or air conditioners  104   l  may optionally be set up to be redundant to each other. For example, the cooling circuit  224  may be cooled and/or supplied by means of a cooling tower, by means of a body of water (e.g., river water and/or lake water), by means of local cooling, by means of district cooling, by means of a chiller, and/or by means of a heat pump  222 . 
     The supply module assembly  202  may optionally include an emergency module  242  that may, for example, supply one or more than one fire extinguishing device  242   l  of the FOC  102  (e.g., comprising an extinguishing gas supply). At least two fire extinguishing devices  242   l  (more generally, fire extinguishing infrastructure  242   l ) of the FOC  102  may optionally be redundant to each other. One fire extinguishing device  242   l  may supply (for example, exactly) one or two FOC  102 , which may be interconnected by means of the lines  242   l . Necessary overpressure openings may be arranged on the face side next to the doors of the airlock  212  close to the ceiling above the normal power distribution  106  and optionally extended to the outside by means of a duct above the medium voltage distribution  218 . 
     Each supply path of one or more than one infrastructures, such as power infrastructure  106 , temperature control infrastructure  114 , telecommunications infrastructure  214  and/or firefighting infrastructure  242   l  may have at least one corresponding pair of mutually redundant connections and/or a pair of supply and return lines at the feed interface  412 . 
     The feed interfaces  412 ,  722 , may be standardized connections, e.g., flanged connections, commercially available plug-in connections, or otherwise. 
       FIG. 3  illustrates a supply chain  300  according to various embodiments in a schematic supply diagram showing a power flow diagram with various technology attachment containers, e.g., supply chain  200 . 
     The supply module assembly  202  of the supply chain  300  may include a ventilation module  302 . The FOC  102  may include an air intake opening  302   a  (e.g., warm air exhaust) and an air output opening  302   z  (e.g., cold air supply) that may be or may be coupled to the ventilation module  302 . The ventilation module  302  may further provide an air duct system  302   l  that interconnects with one another the air intake opening  302   a  and the air discharge opening  302   z , as well as the outside air opening  302   o  and the exhaust air opening  302   f.    
     The air duct system  302   l  may include a recirculation bypass  302   u  and a heat removal bypass  302   v . By means of open air dampers  312   v  and closed dampers  312   w , recirculation mode may be run via the recirculation bypass  302   u . By means of closed air dampers  312   v  and open dampers  312   w , it is possible to run in outdoor air mode (also referred to as free cooling). With partially open air dampers  312   v  and  312   w , the supply air  302   z  (free cooling) may be increased to a minimum temperature level in outdoor air mode by means of a partial volume flow via the recirculation air bypass  302   u  (supply air temperature control). The air duct system  302   l  may include at least one fan  302   p  configured to draw air from the FOC  102  by means of the air intake opening  302   a  (warm air exhaust), pass the air over a heat exchanger  302   k  (e.g., cool it by means of the heat exchanger), and supply the air by means of the air delivery opening  302   z  (e.g., cold air supply) (also referred to as recirculation operation). The fan  302   p  may also perform a function of conveying cold air via the outdoor air opening  302   o  through the supply air opening  302   z  (also referred to as free cooling). The fan  302   k  may also perform a function of maintaining the FOC  102  at a positive pressure to prevent or minimize dust or smoke ingress, such as when doors are opened. 
     An air filter  312   f  may be arranged as close as possible to the outside air opening  302   o  to filter the outside air or additionally the recirculated air and to keep the FOC  102 , the duct system  302   l  and its components  302   p ,  302   k  and optionally the components  312   p ,  202   e  as dust-free as possible. 
     The ventilation module  302  may further include a heat pump  222  with its fluid lines  2221  and one or more heat exchangers  302   k  for the side to be cooled and  302   e  for the heat output. The heat pump(s) or chiller(s) are powered by, for example, normal current  106   n.    
     Alternatively, the heat exchanger  302   k  may be cooled by means of a body of water (e.g., river/lake water), by means of local cooling, by means of remote cooling, by means of a chiller  302   w , and/or by means of the heat removal pipe system  224 . 
     The ventilation module  302  may further include a heat dissipation arrangement  302   v  configured to dissipate thermal energy to the outside and to avoid attachments outside the container  302 . The heat dissipation arrangement  302   v  may include a heat exchanger  302   e  coupled to the heat pump  222  via the piping system  2221 . The heat dissipation arrangement  302   v  may further comprise an additional fan  312   p , which is arranged to pass colder outside air  302   o  through the heat removal bypass  302   v  and over the heat exchanger  302   e , and to discharge heated air to the outside air via an exhaust air grille  302   f . In this case, the air flow is directed through the open air dampers  312   v  and blocked by the closed dampers  312   w.    
     For example, the ventilation module  302  has an air flow rate in the range of 1000 to 11000 m 3 /h (cubic meters per hour) at a compression of 50 to 200 Pa (Pascal), for example, an air flow rate in the range of 9000 to 11000 m 3 /h at a compression of 75 to 175 Pa, or for example, an air flow rate in the range of 9800 to 10200 m 3 /h at a compression of 100 to 150 Pa. 
     For example, the heat exchanger  202   k  may have an output of 90 kW or more, and the heat pump may have a rated heat output of 120 kW or more. 
       FIG. 4  illustrates a computing center module  151  according to various embodiments in a schematic supply diagram  400 . The computing center module  151  may include two FOC  102  (also referred to as a pair of containers) coupled to each other by means of their CC interfaces  402 . The computing center module  151  (e.g., each FOC  102  thereof) may optionally be coupled to a supply module assembly  202  by means of its feed interface(s)  412 , e.g., according to supply chain  200  or  300 . 
     Each FOC  102  of the pair of containers may have the feed interface  412  opposite the CC interface  402 , which may optionally be coupled to the supply module assembly  202  associated with the FOC  102  or coupled to one or more of the central supply systems  202   z ,  202   k ,  202   f . The CC interface  402  may be configured to couple the supply lines of the infrastructures (e.g., the power supply infrastructure, the telecommunications infrastructure, and/or the temperature control or gas extinguishing infrastructure) of the two FOC  102 . For example, the infrastructures of the two FOC  102  may be set up mirror-symmetrically with respect to each other for this purpose, e.g., their CC interface  402  and/or supply lines. 
     The CC interface  402  allows the components of the supply module assembly  202  that are redundant to each other for one FOC  102  to be used for two FOCs  102 . For example, one or more than a first port  202   a  of the feed interface  412  (also referred to as the first feed port  202   a ) of the first FOC  102  may be or may be coupled to a second FOC  102  by means of the CC interface  402  thereof. Alternatively or additionally, one or more than one second feed port  202   b  of the second FOC  102  may be or become coupled to the first FOC  102  via its CC interface  402 . A plurality of first feed ports  202   a  and/or a plurality of second feed ports may be arranged redundantly with respect to each other and/or on opposite sides of the feed interface  412 . Each first and/or second feed port  202   b  may be configured to supply power, telecommunications, and/or extinguishing gas, for example. 
       FIG. 5  illustrates a computing center module  151  according to various embodiments in a schematic supply diagram  500 . The computing center module  151 , its FOC  102 , may be coupled to multiple supply module assemblies  202 , e.g., according to supply chain  200  or  300 . 
     Each FOC  102  may include three contiguous loose walls  102   s . To form the computing center module  151 , the loose walls  102   s  of each FOC  102  may be opened (e.g., disassembled) and the adjacent FOC  102   s  may be physically connected to each other using an expansion joint. In other words, a loose wall  102   s  may include a demountable or pivotable supported wall element (illustratively, a large door). However, the loose walls  102   s  may be configured in other ways. For example, a loose wall  102   s  may include a folding door (also referred to as a folding wall). 
     Thus, a first loose wall  102   s  and a second loose wall  102   s  of each FOC  102  facing another FOC  102  may be or may become open. The first loose wall  102   s  may be opened to expose the front-facing CC interface  402 . A third loose wall  102   s  may be opened to expose the front-facing feed interface  412 . Optionally, the feed interface  412  and the CC interface  402  may be arranged and implemented in the same or mirrored manner (e.g., same diameters and spacing). 
     For example, the fourth sidewall  112   s  (also referred to as the fixed wall  112   s ) may be monolithically configured and/or materially bonded to or part of the housing structure of the FOC  102 . 
     Along the longitudinal extent of each FOC  102  (i.e., on the longitudinal sides thereof), the FOC  102  may include two aisles  102   g ,  112   g  between which the computing device  104  is disposed and each of which is disposed between the computing device  104  and a side wall of the FOC  102  (e.g., spatially separating the side walls). A first aisle  112   g  adjacent to the second loose wall  102   s  may be narrower than a second aisle  112   g  adjacent to the fixed wall  112   s . In other words, the computing device  104  may be disposed closer to the second loose wall  102   s  than to the fixed wall  112   s.    
     This allows a wider computing device  104  to be installed without making the aisle width too narrow. Illustratively, the second aisles  112   g  of the FOC  102  may be contiguous and thus connected to each other (to form a center aisle  112   g ,  112   g ) by means of the opened second loose wall  102   s  so that sufficient aisle width is provided. For example, the width of the center aisle may satisfy a pre-certification requirement or accommodate a customer request for sufficient maintenance space. Alternatively or additionally, the aisle width of each second aisle  112   g  may be less than 0.7 m (meters) and/or greater than 0.3 m. Alternatively or additionally, the aisle width of each first aisle  102   g  may be greater than 0.7 m (meters). 
     The gas extinguishing interface  242   l  may be used to efficiently supply the room network of two FOC  102  set up next to each other from (e.g., exactly) one gas extinguishing control center  202   f  or one gas cylinder system  242  or one control system in accordance with the standards. 
     More than two FOC  102  may be arranged horizontally side-by-side as shown in supply diagram  500 . Alternatively, or additionally, more than two FOC  102  may be arranged on top of each other (e.g., stacked). 
     The pair of FOC  102  coupled together by means of the CC interface  402  may be designated as a first type container pair. Two first type container pairs may each form the center aisle  112   g ,  112   g . Alternatively, or in addition to a first type container pair, an FOC  102  may be used that includes two computing devices and infrastructures that are mirrored symmetrically to each other (such that the CC interface  402  is omitted). 
     In other words, an FOC  102  may stand alone and/or be connected at the short end(s) to a supply module  202  (e.g., comprising a technology container, an electrical container, and/or a hydraulic container) and optionally to a ventilation container  302  (cf.  FIGS. 2 and 3 ). 
     In an additional deployment configuration, two FOCs  102  (e.g., two 20 ft containers) may be combined with the short end face to form a composite (e.g., a 40 ft variant) (also referred to as a longitudinal composite). Alternatively, or in addition to the longitudinal composite of two FOCs  102 , a larger one (e.g., a 40 ft container) may be used, which allows the interface  402  ( FIG. 4 ) between the two FOCs  102  to be unnecessary. 
     But also two FOCs  102  may be combined (also referred to as a wide composite) via the long loose wall  102   s  to create a wider rear or center maintenance aisle without having to create a longitudinal grouping (e.g., a 40 ft grouping) via the interface  402  (see  FIG. 5 , upper wide grouping or lower wide grouping of computing center module  151 , respectively). However, a large wide grouping (general room grouping) may also be established using four FOCs  102  ( FIG. 5 ), for example, two FOCs  102  each of which are provided as a longitudinal interconnect. 
     Alternatively or additionally, a vertical combination/extension may be made until, for example, a maximum of 6 FOCs  102  are arranged one above the other. 
     The basis of all set-up configurations may be the same or a symmetrically constructed platform of the FOC  102 , which may be merely mirror symmetrical with respect to the outer walls  102   s  of the FOC  102 . 
     An FOC  102  as an IT container may be connected individually or in a grouping optionally with one or more technology containers and/or one or more electrical containers, hydraulic containers or fire-fighting containers and other infrastructure components such as generators directly or indirectly to form a computing center. 
       FIG. 6  illustrates a computing center  600  according to various embodiments in a schematic supply diagram. Multiple computing center modules  151  of computing center  600  may be arranged horizontally side-by-side as shown in supply diagram. Alternatively or additionally, multiple computing center modules  151  of computing center  600  may be arranged on top of each other (e.g., stacked). 
     Each container pair  602  of each computing center module  151  may be coupled to two supply module assemblies  202 , e.g., according to supply chain  200  or  300 . The two supply module assemblies  202  may be redundant to each other and/or each may be coupled to two container pairs  602  (e.g., using separate supply lines  642 ). 
     The computing center may include a medium voltage main distribution  604  coupled to each supply module assembly  202 . Each supply module assembly  202  may optionally be coupled to a fuel supply  606  (e.g., supplying gas or diesel). Each supply module assembly  202  may include a plurality of modularly-provided supply devices (then also referred to as modules), e.g., a transformer  612 , a power generator  220 , a low voltage main distribution  218 , a UPS  216 , a normal power distribution  616 , a cold water supply  618  (e.g., chilled water generation  618 ), a cooling tower  620 , a heat pump system  222 , and/or an emergency module  242  (e.g., including a firefighting gas reservoir). 
     In various embodiments, the heat pumps  222  of the supply module assembly  202  are high temperature heat pumps. Depending on the heat pump, heat may then be extracted from the FOC  102  from a temperature level of, for example, at least 30° C., for example, at least 40° C., for example, at least 50° C., for example, at least 60° C., and this heat may be raised to a higher temperature level of, for example, at least 50° C., for example, at least 60° C., for example, at least 70° C. or 85° C. 
     Alternatively, or in addition to the chiller  618 , a district cooling connection  618   f  may be provided. In addition to the heat pump system  222  in conjunction with the cooling tower  620 , a district or local heat line  222   f  may be connected to put the waste heat to use. 
       FIG. 7  illustrates a pre-certified FOC  102  according to various embodiments in a schematic body diagram  700 . The FOC  102  may include at least three loose walls  102   s  in its housing structure  1102   g , optionally a fixed wall  112   s , and one or more than one infrastructure  702  (e.g., the power supply infrastructure  106 , the temperature control infrastructure, and/or the telecommunications infrastructure). For example, the fixed wall  112   s  may extend along a longitudinal extent of the FOC  102  and/or may be disposed on a longitudinal side of the FOC  102 . The fixed wall  112   s  and the second loose wall  102   s  (also referred to as longitudinal side walls) may be disposed opposite each other. Further, the first loose wall  102   s  and the third loose wall  102   s  (also referred to as front side loose walls) may be arranged opposite each other. 
     An intermediate wall  102   z  (e.g., fixed between the housing structure) may be disposed between each of the computing device  104  and the first loose wall  102   s  and the third loose wall  102   s . The computing device  104  and/or the supply lines  702   l  of the infrastructure  702  may be disposed between the two intermediate walls  102   z . Each intermediate wall  102   z  may optionally include a door opening  712  in which, for example, a door  712   t  (also referred to as a personnel door  712   t ) may be disposed. The door opening  712  may have a width of, for example, less than half the internal dimension of the FOC  102  and/or as about 1.5 m, for example as about 1 m. The personnel door  712   t  may be a security door. The security door  712   t  may be configured to be lockable and/or fireproof and/or smokeproof. For example, the security door  712   t  may provide access control. 
     Further, the infrastructure  702  may include at least one pair (e.g., two pairs) of mutually redundant supply paths  702   u , each pair of which couples the feed interface  412  to the computing device  104 . For example, each computing unit  104   a ,  104   b  of computing device  104  may be coupled to a pair of mutually redundant supply paths  702   u . To this end, the computing unit  104   a ,  104   b  may be configured, for example, to switch between a pair of mutually redundant infrastructure couplings  704   n  (e.g., per computing unit  104   a ,  104   b ) of the computing device  104 . Alternatively or additionally, the infrastructure  702  may be arranged to switch between the mutually redundant supply paths  702  of a pair. The switching may be performed, for example, by means of an automatic transfer switch. The infrastructure coupling may be arranged to couple the infrastructure to the computing device  104 . For example, the infrastructure coupling may be a power supply or a telecommunications device of the computing device  104 . 
     For example, the feed interface  412  may include at least a pair of mutually redundant feed ports  412   a ,  412   b , of which a first feed port  412   a  is coupled to the computing device  104  (e.g., each computing unit  104   a ,  104   b ) by at least a first supply line  702   l , and a second feed port  412   b  is coupled to the computing device  104  (e.g., each computing unit  104   a ,  104   b ) by at least a second supply line  702   l . Each of the supply paths may include, for example, a plurality of supply lines and/or a distribution unit that couples the plurality of supply lines to the feed interface  412 . 
     Optionally, the infrastructure  702  may couple the feed interface  412  to the CC interface  402 . For example, the CC interface  402  may include mutually redundant CC ports  402   a ,  402   b , at least a first CC port  402   a  of which is coupled to the at least one first feed port  412   a , and at least a second CC port  402   b  of which is coupled to the at least one second feed port  412   b . The CC interface  402  and/or the feed interface  412  may each be located on different intermediate walls  102   z.    
     Optionally, an additional intermediate wall  102   z  may be disposed on the fixed wall  112   s , and may support one or more than one component of the FOC  102 , e.g., the infrastructure  702 , a user interface, or the like. The additional partition  102   z  allows the fixed wall  112   s  to remain unchanged and/or provides additional thermal insulation to the FOC  102 . 
     For example, the pre-certified FOC  102  may be transported internationally via the established container distribution channels of truck, barge, ocean-going container ship. The FOC may be unaltered externally to retain the international CSC certificate or other transport certificate (e.g., for international transport) and/or to look as inconspicuous as possible. For example, all container exterior walls may be substantially fully unfinished (e.g., without holes or internals) in order to retain the CSC certification for international transport. This is made possible, for example, by means of the partition walls  102   z.    
     For example, the FOC  102  (or computing device  104 ) may be set up to be highly reliable, through a redundant infrastructure  702  that meets, for example, the requirements of a European and/or international certification regarding the reliability of the computing device  104  (e.g., at least according to availability class 3). Illustratively, the FOC  102  may enable the highest possible output density with high reliability and practical interior design typical of a computing center. Further, maximum applicability may be achieved, e.g., by the FOC  102  being a standard 20 ft container, a standard 40 ft container (e.g., for scaling), or a standard 10 ft container. Optionally, by a symmetrically mirrored design of multiple FOC  102 , pairing and thus increased modularity may be achieved. Alternatively or additionally, the media supply (for example energy, temperature control fluid, fresh air, communication, etc.) may be provided from the outside by means of modular supply devices, e.g. by means of front-attachable building services containers. The FOC  102  may optionally have a raised floor for electrostatic discharge and/or to accommodate the supply lines. 
     The FOC  102  may be designed as a container that may be opened on multiple sides (e.g., three sides), which may be fed in (e.g., has media fed in) on only one end face and/or has a personnel door on only one end face, so that a computing center that may be scaled in 4 directions (up, left, right, and toward the other end face) may be formed. 
     The use of the second aisle  112   g  on both sides (as a maintenance aisle) compensates for the narrow width of the FOC  102 . This compensates for the lack of space behind the computing units  104   a ,  104   b . One or more than one loose wall  102   s  may be opened, e.g., removed, if needed, e.g., an expansion with additional FOC  102 . 
     The or each FOC  102  of the computing center module  151  may be commissioned at a site that (e.g., its supply module assembly) also meets reliability requirements (e.g., Internet speed, seismic reliability, flood reliability, power availability, etc.). For example, the site may have: two separate power feeds, two connections from different Internet service providers (e.g., fiber optics), an optional heat network to remove reused waste heat, an optional district cooling connection and/or deep water connection, an optional gas connection, an optional potable and/or waste water connection. 
     One or more than one medium may be provided locally by means of the supply module assembly  202 , e.g., cold water (having about 18° C. and/or 24° C. and/or having a temperature difference of 6 Kelvin or more), dry cooling (e.g. by means of gas), a low voltage 400 V (alternating current—AC) generated from a medium voltage (by means of a transformer  612 ), an uninterruptible current (e.g., by means of UPS), an optional generator current (e.g., by means of a generator), an optional central extinguishing gas, an optional central water-to-water heat transfer. 
     For example, the UPS may include an electrical energy storage device (e.g., storage batteries or other batteries) configured to provide power according to the power consumption of the computing device for several minutes (e.g., about 15 minutes or more). The generator may optionally include a storage tank adapted to hold fuel (e.g., gas or diesel) according to a consumption of the generator for at least 24 hours (e.g., 72 hours or 96 hours or more). The water-to-water heat transfer may be or may be provided by means of a heat pump, e.g., a high temperature heat pump system. 
     The infrastructure  702  may be arranged to meet the requirements of availability class 2 or higher (e.g., availability class 3) with respect to the reliability of the computing system  104  and may be pre-certified accordingly, e.g., in accordance with Tier and/or in accordance with DIN EN 50600. 
     The enclosure structure (e.g., fixed wall) of the FOC  102  may be steel, which may optionally include one or more personnel doors. The enclosure structure of the FOC may include four corner steel beams and their horizontal steel connecting beams (and optionally the floor structure), which are adjacent to the partitions  102   z . The enclosure structure may be configured to support the weight of the one ore more FOCs  102  (e.g., at least two or three times thereof). Thus, multiple FOCs  102  may be stacked on top of each other (e.g., up to 8 FOCs  102 ). Optionally, the FOC may be free of windows (e.g., glazing). Each loose wall  102   s  may be a non-load bearing sidewall, the removal of which does not substantially affect the load bearing capacity of the FOC  102 . 
     The end-face intermediate walls  102   z  may, for example, be set up to be burglar-proof (e.g., made of metal) and optionally have lockable and/or burglar-proof doors  712   t  that are connected to one another by means of the first gangway  102   g . The burglar-proofing of the intermediate walls  102   z  or at least of the personnel door(s) may, for example, meet the requirements of a resistance class (RC) according to DIN EN 1627 (of 2011), e.g., resistance class 2 (RC2) or more, e.g., resistance class 3 (RC3) or more. The end-face intermediate walls  102   z  may be designed as tight and pressure-resistant walls stable (e.g. with a reduced stud spacing) in such a way that an extinguishing gas system  242  or  202   f  causes less or no (illustratively inadmissible) deflections in the event of a triggering and/or be equipped with an overpressure flap  242   k  (e.g. at the top next to the door opening  712  in the dimensions 250×250 mm or smaller) which allows a safe discharge of an extinguishing gas. 
     The optional raised floor of the FOC  102  may serve to protect the engineering equipment, to elevate the lower edge of the door above snow level and/or flood protection. The supply lines may be arranged in the raised floor. This also increases safety. The raised floor may optionally include one or more than one fire alarm (e.g., at least two lines, for alarm externally or activation of an extinguishing gas system/triggering or extinguishing gas system) and/or an extinguishing gas outlet or pressure relief opening to the outside or within the raised floor. Optionally, the raised floor may have a connection to a smoke aspiration system or an early smoke detection system for a pre-alarm and a shutdown of all ventilation systems. 
     Optionally, the CC interface may be set up as a feed interface, which enables a two-sided media supply. For a two-sided media supply to the FOC  102  (e.g., with cooling fluid and/or power), there may be twice as many supply lines (e.g., twice the redundancy, e.g., 2·(N+1)), which further increases the power that may be dissipated (to e.g., 250 kW or more). Alternatively or additionally, a path redundant supply from the ice feed interface  412  and the CC interface may be enabled, e.g., with electrical power. 
     For example, the supply lines of the temperature control infrastructure  114  may pass completely through the FOC and/or flange covers or blind flange covers of the docking interfaces  722  at the end faces of the FOC  102 . Shut-off valves at each end and/or between two computing units  104   a ,  104   b  may allow redundancy switching and/or two-sided media supply. 
     The power supply infrastructure  106  may include two separate UV  106   u  and/or cable trays separated from each other, for example, to meet availability class 2 (e.g., Tier 2) and above requirements (e.g., supplying UPS power A and B). The cable runs may be continuous throughout the FOC  102  in the raised floor to provide, for example, two supply paths away from each other from the feed interfaces  412  on opposite ends of the FOC  102  (e.g., first power supply on the left and second power supply on the right for a 40-ft FOC). Each supply path or UV  106   u  may be configured to provide a supply power of at least 250 kW (kilowatts) or less. For example, the cross-section of the supply lines of each supply path may be arranged to provide supply power at either 220 V (volts) or at 110 V. Alternatively, or additionally, each supply path of the power supply infrastructure  106  may be arranged to provide power of about 250 kW or more per 6 meters of longitudinal extent of the FOC  102 , and/or in aggregate to provide about 500 kW or more (e.g., with less or no redundancy). 
     For example, the base power supply by means of the power supply infrastructure  106  does not necessarily need to be or be backed up by means of a UPS and/or may be provided by means of a backup generator. For example, the FOC  102  may be free of a heat pump and/or a UPS  216 . 
     Each power supply path of the power supply infrastructure  106  may, for example, have multiple (e.g., four) connector strips and/or separately carry and/or protect three power phases. Each of the power strips may optionally be configured to switch, by means of an automatic transfer switch, to the other of the power supply paths in the event of a failure of one of the power supply paths. This allows components of the computing device  104  that do not have two power supplies to be provided with reliable power. 
     Each power supply path (e.g., its connector strip) may optionally be coupled to the telecommunication infrastructure  914  and/or implement a remote access protocol that is arranged to control and/or read out the power supply path by means of the telecommunication (e.g., a network and/or the Internet). For example, this may allow temperature and/or power to be read. The remote access protocol may alternatively or additionally implement a serial on and/or off switching of the power strips. This prevents electromagnetic fields that are too strong. 
     Optionally, the supply paths  702   l  of the or each pair of mutually redundant supply paths  702   l  (e.g., of the power supply infrastructure and/or the telecommunications infrastructure) may be arranged on opposite sides (e.g., the long sides) of the FOC  102  (e.g., the computing device may be arranged between them). Thus, for example, an availability class of 3 or 4 may be achieved. 
     Optionally, the FOC  102  may be configured to provide a mirroring of the data from the computing device  104  to another FOC of the or another computing center module  151  using the CC interface  402 . 
     Further, the FOC  102  may include a fire extinguishing device that satisfies the pre-certification requirements. For example, a fire extinguisher may be located in each FOC  102 , which may satisfy an availability class 1, for example. For an availability class of 2 or more, a fire extinguishing device of the FOC  102  may include an early fire warning system (e.g., comprising a smoke or heat detector) and/or automatically request and/or supply an extinguishing agent (e.g., the extinguishing gas) to the interior of the FOC  102  upon detection of a fire. Optionally, the fire extinguishing device of the FOC  102  may be configured to supply an extinguishing agent (e.g., gas) in a volume predetermined in accordance with the pre-certification and/or provide extinguishment within a time predetermined in accordance with the pre-certification. For example, the early fire warning system may be arranged to draw air from the raised floor and/or the UV  106   u  and the computing device  104  and check for the presence of smoke particles. 
       FIG. 8  illustrates several availability classes according to different embodiments in a schematic diagram  800 . Each of the availability classes 1 to 4 may have requirements for the infrastructure  702  (e.g., the power supply infrastructure, the temperature control infrastructure, and/or the telecommunication infrastructure) of the FOC, which are met individually by each FOC  102  of the computing center module  151 , so that it may also be or become pre-certified if, for example, the corresponding structural and safety requirements are also met.

     According to availability class 4, the power supply infrastructure may have at least two supply paths, each supply path of which is set up to be fully maintenance-tolerant, the telecommunications infrastructure may have multiple fixed supply paths, the supply lines of which are located on different sides of the FOC, and the temperature control infrastructure may have multiple supply paths, the supply lines of which are located on different sides of the FOC.

     The requirements for the availability class(es) may be defined, for example, according to DIN EN 50600. 
       FIG. 9  illustrates a supply chain  900  according to various embodiments in a schematic supply diagram with schematic redundancy pairing  901 . The supply chain  900  may include the supply module assembly  202  and the FOC  102 . For example, the supply chain  900  may be arranged as the supply chain  200  or  300 , but the FOC  102  may be or may be provided without the supply module assembly  202 . The feed interface  412  may be disposed within the housing  1102   g  of the FOC  102  (also referred to as the container housing  1102   g ). 
     The temperature control infrastructure  114  (e.g., comprising the air conditioning  104   l ) may comprise at least one pair of mutually redundant supply paths, each supply path comprising a hot water and/or cold water connection  952  (e.g., flanges) at the feed interface  412 .

     For example, this supply chain  900  may correspond to the construction of an availability class 3 computing center of which the one or more FOCs  102  are a part. 
       FIG. 10  illustrates a supply chain  1000  according to various embodiments in a schematic supply diagram. The supply chain  1000  may be set up, for example, like the supply chain  200 ,  300 , or  900 . The FOC  102  may also be or be provided without the supply module assembly  202 . 
     The power supply infrastructure  106  may include at least a pair of mutually redundant power supply paths, e.g., a first power supply path  106   a  (also referred to as supply path A) and a mutually redundant second power supply path  106   b  (also referred to as supply path B), each of which power supply paths may include a UV  106   u  and may be coupled to a power supply  104   n  of the computing device. The power supplies  104   n  may be redundant with respect to each other and/or arranged to provide electrical power to the processors  104   p  (or computing devices). The or each UV  106   u  (also referred to as tertiary distribution device  106   u  or tertiary distribution) may include one or more than one protected outlet  1002  (e.g., in the form of a power strip, also referred to as a power distribution unit or PDU). Each of the power outlets  1002  may be coupled to one of two mutually redundant power supplies  104   n  of the computing device  104 . 
     The tertiary distribution device  106   u  may be understood descriptively as horizontal distribution wiring, i.e., the distribution of supplied power within an FOC  102  (also referred to as floor wiring) to various subsystems. 
     For example, the power distribution in the FOC  102  (tertiary distribution) for an availability class 3 may be the same as the availability class 2 and/or the availability class 4. According to the availability class 3, the FOC  102  may have a pair of power feed terminals  916  (A and B) and/or a pair of electrical UPS  106   u  (tertiary distribution), each of which may be switched between (e.g., using a transfer switch). 
       FIG. 11  illustrates a supply chain  1100  according to various embodiments in a schematic supply diagram. The supply chain  1100  may be set up, for example, like the supply chain  200 ,  300 ,  900 , or  1000 . The FOC  102  may also be or be provided without the supply module assembly  202 . 
     The telecommunications infrastructure  194  may include at least one pair of mutually redundant telecommunications supply paths, for example, a first telecommunications supply path  914   a  and a second telecommunications supply path  914   b , each of which telecommunications supply paths may include a telecommunications interface  924   s  and at least one telecommunications distribution. The at least one telecommunications distribution may include a main distribution  1102 , an intermediate distribution  1104 , and/or a zone distribution  1106 . 
     Each of the telecommunications supply paths  914   a ,  914   b  may be coupled to one of two mutually redundant telecommunications devices  104   t  of the computing device  104 . The mutually redundant telecommunications devices  104   t  may be arranged to connect the processors  104   p  (or computing devices) to a network and/or process messages according to a telecommunications protocol. 
     In the following, various examples are described that relate to what has been described above and what is shown in the figures.
