Description:
BACKGROUND OF THE INVENTION 
       [0001]    1. Field of the Invention 
         [0002]    This invention relates to a building module for a shared data center facility appropriate for a multi-tenant office building which can be integrated in situ directly with the building cooling, power, fiber optics and security systems or as an option, can be provided and operated with external, self-contained systems. 
         [0003]    2. Description of the Prior Related Art 
         [0004]    Data centers with modular components suitable for use with rack or shelf mount computer systems can be prepackaged as shown in U.S. Pat. No. 7,278,273 in self-contained, fixed unit packages. This has the disadvantage of not being able to be integrated within traditional commercial office building developments and not flexible enough to be integrated into a building cooling infrastructure, building power systems and building fiber optics riser infrastructure. Additionally, prepackaged systems do not provide the level of access, level of multi-customer security, deployment flexibility in varied equipment installations and long term changes in integration options that may extend the lifetime of a commercial structure. Finally, the use of containers for integration into commercial office structures is impractical and wasteful of materials. 
         [0005]    As stated in this patent, many of today&#39;s more complex computing systems such as computer server systems are designed for rack oriented housing to maintain operating and space efficiencies, having a number of removable electronics modules, such as electronics trays positioned and stacked relative to each other in a shelf-like manner within a frame or rack. The rack-mounted systems allow the arrangement of several electronics modules in a vertical orientation for efficiency of space. Each electronics module can be slid into and of the rack-mounting system. Each electronics module may correspond to a different and or each electronics module may hold one or more components of a server. Examples of electronics modules include modules for processing, storage such as random as memory (RAM), network interfaces and controllers, drives such as floppy disk drives, hard drives, compact (CD) drives, and digital video disk (DVD) drives, lid and serial ports, small computer systems interface (SCSI) bus controllers, video controllers, power supplies, and so forth. 
         [0006]    In situ installation usually consists of a server farm housed in a data center such as a colocation and may include hundreds of racks that hold various types of computered modules or very small installations located within the user&#39;s leased office space within the commercial office building which house company specific computer modules. When the server racks are installed in the colocation site the computing location is removed geographically from the actual computing location of the end users creating a disconnection of computing and use. When the server racks are installed within tenant&#39;s suite, the computing equipment is housed locally and therefore achieves higher performance, more convenience for maintenance and lower operating costs though the location is below the best standard of care in housing computing equipment. Each of these solutions presents unique barriers to cost, time and materials efficiencies that are remedied through the insertion of purpose built, integrated facilities within the commercial office property to serve the tenants of that property. 
         [0007]    As an example, locating servers in a remote facility requires company information technology employees to drive or fly long distances to manage and maintain servers with a physical presence. This process creates time inefficiencies for change management of systems, time inefficiencies for employees required to travel to remote locations and energy loss for transportation requirements. 
         [0008]    Also, the current system of tenants operating their own computer rooms within their tenant office suites presents significant shortcomings in data center services, energy efficiencies and operational efficiencies. Due to limitations in economies of scale tenants are unable to access core data center requirements such as generator power, 24/7 cooling flow, redundant fiber optic access, scalable space requirements, centralized battery backup systems and non-data center fire suppression without significant cost requirements. Therefore tenants are typically dependent on substandard computer rooms to house their information. The substandard housing of computer equipment limits future technology innovation by presenting a barrier of dependency on the systems based on reliability concerns. Additionally, due to the lack of economies of scale of the facility construction, the ability to integrate with the central building cooling systems is limited creating inefficient cooling designs. This inefficient cooling design increases overall building and larger scale aggregate society energy usage placing the economy at a disadvantage and driving costs higher. A direct effect of the inefficiency is the increased costs of electricity within the commercial property causing price increases and decreasing demand and therefore utilization. Additionally, due to economies of scale, management and maintenance of small facilities places an undue burden of management on tenants and landlords creating a cost and performance inefficiency. Centralization of services places trained professionals in charge of facility management allowing Information Technology specialists the ability to focus on Information Technology tasks. 
         [0009]    Thus, neither in suite facilities, prepackaged or offsite colocation data centers are cost efficient or user friendly. 
       SUMMARY OF THE INVENTION 
       [0010]    This invention discloses a centralized common area data center solution for tenants of multi-tenant commercial office properties which provides significant value in services and cost savings to both landlord and tenant. The centralized modular facility design provides increased access to high technology services for tenants of the properties while delivering significantly decreased energy and materials utilization for the landlord. Furthermore, tenants and related parties receive significantly improved operational efficiencies greater than individual tenant suite facilities without having to resort to offsite colocation all the while providing a base of innovative resources within the property for other future products and services development and delivery. The offering and provision of a customized module in situ, rather than a prepackaged module creates an integrated solution suitable for the unique requirements of commercial office construction. 
         [0011]    Modular data centers with modular components suitable for use with rack or shelf mount computing systems, for example, are disclosed and it should be appreciated that the present invention can be implemented in numerous ways, including as a process, an apparatus, a system, a device, or a method. Several inventive embodiments of the present invention are described below. 
         [0012]    According to a sample embodiment, a modular data center in accordance with carrying out the invention generally includes a reduced scale modular room including for example, a compressor, a condensing coil, heat exchanger, pumps, controls, and/or motors for a temperature control system. The modular data center may additionally include evaporative, compressed fluid, or other suitable cooling system in communication with modular computing systems mounted within rack and/or shelf mounting structures and each mounting structure may be enclosed in an enclosure with an access door, each enclosure being associated with a master temperature control subsystem. Each temperature control subsystem may include a blower and an evaporator coil, the blower including a blower motor and blower blades container, respectively. The enclosure may also define a delivery plenum and a return plenum in thermal communication with the corresponding temperature control subsystem and with the computing systems contained within the corresponding enclosure. This enables 24/7/365 cooling to be provided, if required, in addition to the building cooling system. The room may also be provided with its own generator or power source as a backup system, fiber optic interconnection, internet service provisioning, access control system, cabling riser management interconnection system, remote systems monitoring and fire suppression system. Finally, the data center room module can also be outfitted with a technician work area, an equipment staging area, a crossconnect room or any combination thereof. 
         [0013]    The benefits are manifold. From the tenant standpoint, there is provided an increase in system reliability, increased environmental stability, increased bandwidth, decreased maintenance requirements, 24/7/365 days monitoring, increased security, reduced time to occupy space and reduced capital cost to build out. From the landlord standpoint, the module is provided in move in ready condition, reduces capital costs to occupy new tenants, reduces material requirements to complete the housing of tenant computer systems, improves ability to upgrade future tenant requirements in a consolidated location, reduces computer room for maintenance expenses, reduces energy consumption required to cool computer systems within the building and balances the cooling requirement of human loads throughout the balance of the property enabling more efficient cooling system design. These and other features and advantages of the present invention will be presented in more detail in the following detailed description and the accompanying figures which illustrate by way of example the principles of the invention. 
     
    
     
       BRIEF DESCRIPTION OF THE DRAWING 
         [0014]    The present invention will be readily understood by the following detailed description in conjunction with the accompanying drawing, wherein: 
           [0015]    The sole FIGURE is a perspective view of an illustrative of tenant modular data center suitable for use with rack and/or shelf mount computing systems. 
       
    
    
     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
       [0016]    A data center facility for a multi tenant commercial office building suitable for use with rack or shelf mount computing systems, is disclosed. The sole FIGURE is a perspective view of an illustrative implementation of a data center facility  10  suitable for use with rack and/or shelf mount computing systems. The data center facility  10  may be constructed in situ in dedicated space  12  provided in multi tenant commercial office building and includes at least one computing module  20  each with multiple computing units on shelves or racks  22 . In the example shown in the sole FIGURE, the data center  10  as is also provided with a power and cooling equipment  14 ,  16  containing power generation equipment and cooling equipment (e.g., compressor(s), heat exchangers, circulation pumps, controls, etc.), network interconnection points, respectively. 
         [0017]    Blower motors (not shown) may extend from the rack or be incorporated within the rack designs  22  to expel and recirculate warm air to produce cooling within the facility, depending upon available space. The racks or shelves  22  may be arranged so as to provide a walkway  28  for service access and/or to facilitate temperature and/or humidity control. In addition, a workbench  30  can optionally be provided, along with an equipment staging area  32 . A access control based security area  34  is also provided in the facility  10  adjacent an entry door or multiple doors  35  along with a crossconnect room  36 . Door  35  is provided adjacent the security area  34  to provide access for service personnel on-site at the data center facility. 
         [0018]    On site, the modular components are interconnected and/or connected to external resources such as cooling equipment, electricity, natural gas, fuel cell power generation, solar power generation, water; and/or Internet connections to form the completed data center. For off-site servicing and/or maintenance, components of the respective modular facility can be disconnected from other modular component(s) and/or various resource connections and transported to a servicing facility, e.g., the factory that built the module or a separate maintenance facility, and then returned to the original. Alternatively, a new replacement component can be brought to the site and the component being replaced can be disconnected and transported to a servicing facility, e.g., the build facility, and optionally placed back into service at the same or a different site. In particular, as each component reaches the end of its service life, the component may be disconnected from the remainder of the modular data center and removed from the site and a replacement modular component may be installed as a replacement. Similarly, as each rack/shelf and/or computing unit within the computing module reaches the end of its service life, that rack/shelf and/or computing unit may be disconnected from the remainder of the computing module and removed from the data center site and a replacement rack/shelf and/or computing unit may be installed as a replacement. Such a modular-method of servicing the modular data center also takes advantage of the use of modular components. 
         [0019]    Furthermore, the modular data center facilitates ease of deployment and therefore widespread deployment of facilities in commercial office properties creates an environment of increased efficiencies and innovation. The design of the facility allows for reduced material requirements and increased performance for tenant computing requirements and thus more economically feasible. In one implementation, a modular system may reduce the cost of moving by approximately 60 to 80% to provide more viable options even within the nominal life of a module and decrease cooling costs for data center users by 80%. 
         [0020]    The facility is also provided with its own systems which are operational 24/7/365 even if the building systems are unavailable or shut down for maintenance. For example, the building cooling system is usually operational between 7 AM and 9 PM; but it may be necessary to cool the computer modules outside of these hours or in a more efficient fashion. The data facility having its own integrated systems can be operated as desired. Further, it may enable the tenant to negotiate a lease wherein after hour power and cooling is not required wherein costs over the term of the tenant&#39;s lease can be capitalized or reduced. The chart below shows the advantages and benefits of the disclosed tenant data center facility:

         [0021]    To reiterate, commercial office properties are served via large scale water chiller and cooling towers. These systems are expensive to run and operate as part of an office lease only during business hours, typically 7 am to 8 pm. Once these systems turn off, the tenant is required to either pay for overtime air conditioning ($30-$50/hr) or provide secondary air conditioning systems within the tenant space to serve the computer room. Central chiller systems also require a consistent supply of water from city systems, therefore systems are shut down during hurricane/emergency scenarios to prevent system failure. 
         [0022]    The module data centers of the present invention operate closed loop 24/7/365 redundant cooling systems separate from building cooling systems providing the consistent cooling design required for the tenant&#39;s data systems. 
         [0023]    Generator space is extremely limited in the commercial office environment. Property owners may be required to have generator power for life safety systems but this power is difficult and expensive to provide elsewhere in the property. Locations to place generators are extremely limited, are expensive and require regular maintenance. The module data center as disclosed in the present invention has consolidated otherwise disparate computer systems enabling the cost effective delivery generator backup power as part of the facility for all customers. This consolidation is also effective for the future incorporation of non fuel or non electrical based power generation such as solar, chemical or geothermal. 
         [0024]    Consolidation of disparate systems into the module facility enables fire suppression systems of a higher caliber to be installed within the facility. Water is the overwhelming choice of commercial office properties for fire suppression. Office fire systems are designed to release in zones making it difficult to isolate computer rooms from a general release. With a module data center as disclosed herein, computer and human safe non-water based fire suppression systems can be provided. 
         [0025]    Electrical consumption is both an issue to reduce carbon footprint as well as a direct financial issue for commercial properties Landlords and tenants. Data Center requirements are the largest per square foot user of energy in a commercial property. The data center of the present invention delivers an extremely high ratio of power to cooling resulting in reduction of energy requirements up to 80% over traditional commercial office computer room cooling designs. Energy efficiency will therefore drive lower costs for all businesses. 
         [0026]    Not only does the tenant data center of the instant invention result in reduced network costs and energy use, but decreased operating expenses, for a one time relatively nominal expense. 
         [0027]    While the preferred embodiments of the present invention are described and illustrated herein, it will be appreciated that they are merely illustrative and that modifications can be made without departing from the spirit and scope of the invention. Thus, the invention is intended to be defined only in terms of the following claims
