The following description in combination with the Figures is provided to assist in understanding the teachings disclosed herein. The description is focused on specific implementations and embodiments of the teachings, and is provided to assist in describing the teachings. This focus should not be interpreted as a limitation on the scope or applicability of the teachings.
FIG. 1 illustrates a general information handling system 100. For purposes of this disclosure, an information handling system may include any instrumentality or aggregate of instrumentalities operable to compute, classify, process, transmit, receive, retrieve, originate, switch, store, display, manifest, detect, record, reproduce, handle, or utilize any form of information, intelligence, or data for business, scientific, control, entertainment, or other purposes. For example, an information handling system may be a personal computer, a PDA, a consumer electronic device, a network server or storage device, a switch router or other network communication device, or any other suitable device and may vary in size, shape, performance, functionality, and price. The information handling system may include memory, one or more processing resources such as a central processing unit (CPU) or hardware or software control logic. Additional components of the information handling system may include one or more storage devices, one or more communications ports for communicating with external devices as well as various other I/O devices, such as a keyboard, a mouse, and a video display. The information handling system may also include one or more busses operable to transmit communications between the various hardware components.
Information handling system 100 includes a processor 102, a memory 104, a chipset 106, one or more PCIe buses 108, a universal serial bus (USB) controller 110, a USB bus 112, a keyboard device controller 114, a mouse device controller 116, a configuration a SATA bus controller 120, a SATA bus 122, a hard drive device controller 124, a compact disk read only memory (CD ROM) device controller 126, a storage 128, a graphics device controller 130, a network interface controller (NIC) 140, a wireless local area network (WLAN) or wireless wide area network (WWAN) controller 150, a serial peripheral interface (SPI) bus 160, a NVRAM 170 for storing BIOS 172, and a baseboard management controller (BMC) 180. In an example, chipset 106 may be directly connected to an individual end point via a PCIe root port within the chipset and a point-to-point topology as shown in FIG. 1. BMC 180 can be referred to as a service processor or embedded controller (EC). Capabilities and functions provided by BMC 180 can vary considerably based on the type of information handling system. For example, the term baseboard management system is often used to describe an embedded processor included at a server, while an embedded controller is more likely to be found in a consumer-level device. As disclosed herein, BMC 180 represents a processing device different from CPU 102, which provides various management functions for information handling system 100. For example, an embedded controller may be responsible for power management, cooling management, and the like. An embedded controller included at a data storage system can be referred to as a storage enclosure processor. System 100 may include any additional components over those shown in FIG. 1 without varying from the scope of this disclosure.
System 100 can include additional processors that are configured to provide localized or specific control functions, such as a battery management controller. Bus 160 can include one or more busses, including a SPI bus, an I2C bus, a system management bus (SMBUS), a power management bus (PMBUS), and the like. BMC 180 can be configured to provide out-of-band access to devices at information handling system 100. As used herein, out-of-band access herein refers to operations performed prior to execution of BIOS 172 by processor 102 to initialize operation of system 100.
BIOS 172 can be referred to as a firmware image, and the term BIOS is herein used interchangeably with the term firmware image, or simply firmware. BIOS 172 includes instructions executable by CPU 102 to initialize and test the hardware components of system 100, and to load a boot loader or an operating system (OS) from a mass storage device. BIOS 172 additionally provides an abstraction layer for the hardware, such as a consistent way for application programs and operating systems to interact with the keyboard, display, and other input/output devices. When power is first applied to information handling system 100, the system begins a sequence of initialization procedures. During the initialization sequence, also referred to as a boot sequence, components of system 100 are configured and enabled for operation, and device drivers can be installed. Device drivers provide an interface through which other components of the system 100 can communicate with a corresponding device.
Information handling system 100 can include additional components and additional busses, not shown for clarity. For example, system 100 can include multiple processor cores, audio devices, and the like. While a particular arrangement of bus technologies and interconnections is illustrated for the purpose of example, one of skill will appreciate that the techniques disclosed herein are applicable to other system architectures. System 100 can include multiple CPUs and redundant bus controllers. One or more components can be integrated together. For example, portions of chipset 106 can be integrated within CPU 102. Additional components of information handling system 100 can include one or more storage devices that can store machine-executable code, one or more communications ports for communicating with external devices, and various input and output (I/O) devices, such as a keyboard, a mouse, and a video display. An example of information handling system 100 includes a multi-tenant chassis system where groups of tenants (users) share a common chassis, and each of the tenants has a unique set of resources assigned to them. The resources can include blade servers of the chassis, input/output (I/O) modules, Peripheral Component Interconnect-Express (PCIe) cards, storage controllers, and the like.
In an example, information handling system 100 may be any suitable device including, but not limited to, information handling system 202 of FIG. 2. Information handling system 100 can include a set of instructions that can be executed to cause the information handling system to perform any one or more of the methods or computer based functions disclosed herein. The information handling system 100 may operate as a standalone device or may be connected to other computer systems or peripheral devices, such as by a network.
In a networked deployment, the information handling system 100 may operate in the capacity of a server or as a client user computer in a server-client user network environment, or as a peer computer system in a peer-to-peer (or distributed) network environment. The information handling system 100 can also be implemented as or incorporated into various devices, such as a personal computer (PC), a tablet PC, a set-top box (STB), a personal digital assistant (PDA), a mobile device, a palmtop computer, a laptop computer, a desktop computer, a communications device, a wireless telephone, a land-line telephone, a control system, a camera, a scanner, a facsimile machine, a printer, a pager, a personal trusted device, a web appliance, a network router, switch or bridge, or any other machine capable of executing a set of instructions (sequential or otherwise) that specify actions to be taken by that machine. In a particular embodiment, the computer system 100 can be implemented using electronic devices that provide voice, video or data communication. Further, while a single information handling system 100 is illustrated, the term “system” shall also be taken to include any collection of systems or sub-systems that individually or jointly execute a set, or multiple sets, of instructions to perform one or more computer functions.
FIG. 2 illustrates an information handling system 200 according to at least one embodiment of the disclosure. Information handling system 200 includes a cover 202, a floating connector assembly 204, and a midplane 206. Cover 202 may provide a cosmetic look to information handling system 200 while allowing access to floating connector assembly 204. In an example, information handling system 200 may be a server or any other similar device. In certain examples, floating connector assembly 204 may be mounted on any suitable component of information handling system 200 including, but not limited to, a compute board, such as compute node 304 of FIG. 3, and a fixed midplane 206. Information handling system 200 may include additional components over those described herein without varying from the scope of the disclosure.
In an example, if floating connector assembly 204 is mounted on a midplane a compute node may be plugged into one side of the floating connector assembly and a pluggable input/output (10) module may plug into the other side of the floating connector assembly. In this example, floating connector assembly 204 may be fixed reference point for each pluggable device to mate with. Floating connector assembly 204 may improve information handling system 200 by the floating connector assembly including tolerances in multiple directions to enable devices with different alignments to plug into the floating connector assembly. For example, floating connector assembly 204 may enable a single field replaceable unit (FRU) to be plugged into the floating connector assembly within information handling system 200, and multiple different FRUs to be plugged in the floating connector assembly from outside of the information handling system. In this example, the multiple different FRUs may have slightly different tolerances and floating connector assembly 204 may adjust to accommodate the different FRUs to be plugged into the floating connector assembly.
FIGS. 3 and 4 illustrate different views of floating connector assembly 204 mounted on a side cover 302 of information handling system 200 according to at least one embodiment of the disclosure. Floating connector assembly 204 includes connector 310 and float brackets 312 and 314. Connector 310 may be placed in physical communication with both float brackets 312 and 314. In an example, one end of connector 310 may be in physical communication with float bracket 312 while the other distal end of the connector may be in physical communication with float bracket 314.
Floating connector assembly 204 may be secured to side cover 302 of information handling system 200 in any suitable manner. For example, a screw or mounting component 320 may physically and securely attach float bracket 312 to side cover 302, and a screw or mounting component 322 may physically and securely attach float bracket 314 to the side cover. In an example, float brackets 312 and 314 may be secured to side cover 302, but connector 310 may be able to move with respect to the float brackets and the side cover. Floating connector assembly 204 will be described in more detail with respect to FIGS. 5-9 below.
FIGS. 5-9 illustrate different views of floating connector assembly 204 according to at least one embodiment of the present disclosure. Floating connector assembly 204 includes connector 310 and float brackets 312 and 314. Referring to FIG. 5, float bracket 312 includes mounting holes 502. One or more of mounting holes 502 may interface with one or more screws, such as screw 320 of FIG. 3, to secure float bracket 312 to side cover 302 of FIG. 3. Similarly, float bracket 314 includes mounting holes 504. One or more of mounting holes 504 may interface with one or more screws, such as screw 322 of FIG. 3, to secure float bracket 314 to side cover 302 of FIG. 3.
Referring now to FIG. 6, connector 310 includes receptacles 602 and 604, and compressible components 606 and 608. In certain examples, receptacles 602 and 604 may be in any suitable shape capable of interfacing with float brackets 312 and 314. For example, receptacles 602 and 604 may be any open shape including, but not limited to, a ‘U’ shape. In an example, each of receptacles 602 and 604 include an end attached to connector 310 and another end, the end distal from the first end, that is the open shape. The open shape of receptacles 602 and 604 may allow connector 310 to float or move in two directions while providing a rigid surface to prevent movement in a third direction.
In an example, receptacles 602 and 604 may be lined with respective compressible components 606 and 608. Compressible components 606 and 608 may be any suitable material capable of being compressed when a force is applied and may reform to its original shape when the force is removed. For example, compressible components 606 and 608 may be a foam, a metal mesh, soft rubber, or the like. In an example, an amount or distance that connector 310 may float in the two directions may substantially correspond to an amount that compressible components 606 and 608 may be compressed. Compressible components 606 and 608 may provide an auto-centering of connector 310 based on the original shape and thickness of the compressible components, and may also be able to enable the connector to float in any two directions.
Float bracket 312 includes openings 610 and a bar 612. Similarly, float bracket 314 includes openings 620 and a bar 622. In an example, receptacle 602 and compressible component 606 may be inserted within openings 610 to interface connector 310 with float bracket 312. Similarly, receptacle 604 and compressible component 608 may be inserted within openings 620 to interface connector 310 with float bracket 312. A resting or auto-centered position of connector 310 may include compressible component 606 to be in physical communication with bar 612 and compressible component 608 to be placed in physical communication with bar 622. A cross section of floating connector assembly 204 taken along line A-A in FIG. 6 is illustrated in FIG. 7.
Referring now to FIG. 7, float bracket 312 includes a backing surface 702, and float bracket 314 includes a backing surface 704. Backing surface 702 may be placed in physical communication with receptacles 602 and backing surface 704 may be placed in physical communication with receptacle 604. In an example, backing surfaces 702 and 704 may provide rigid support for receptacles 602 and 604 from an insertion force is exerted on connector 310 when cable or other connector is plugged into the connector.
In certain examples, bars 612 and 622 may be in any suitable shape. For example, a portion of bar 612 towards connector 310 may be substantially the same shape as receptacle 602, such as ‘U’ shaped. Similarly, a portion of bar 614 towards connector 310 may be substantially the same shape as receptacle 604, such as ‘U’ shaped. Based on bars 612 and 614 being substantially the same shape as receptacles 602 and 604, connector 310 may be auto-centered within floating connector assembly 204.
In an example, floating connector assembly 204 may be connected together in any suitable manner. For example, one of float brackets 312 and 314 may be secured to a side cover of an information handling system, such as side cover 302 of information handling system 200 in FIG. 3, and the other float bracket may be placed in physical communication with connector 310. In an example, float bracket 314 may be secured to the side cover at any point, such as the float bracket may be pre-assembled into information handling system 200.
Connector 310 may be placed in physical communication with float bracket 312 by in the direction of arrow 706, and receptacle 602 may be inserted through openings 610 until compressible component 606 is placed in physical communication with bar 612. Connector 310 and float bracket 312 may be moved in the direction of arrow 708 until receptacle 604 is inserted into openings 620 of float bracket 314. In response to connector 310 being in physical communication with both float brackets 314 and 314, float bracket 312 may be secured to the side cover. Based on connector 310 being in physical communication with both brackets 312 and 314, floating connector assembly 204 may be fully connected together as shown in FIG. 8.
Referring now to FIG. 8, compressible components 606 and 608 within respective receptacles 602 and 604 may allow connector 310 to float in x and y directions as illustrated by arrows 802 and 804, but may prevent movement of the connector in the z direction. In an example, the float or movement of connector 310 in the two directions may allow components with different alignment tolerances to plug into the connector, and the rigidity of receptacles 602 and 604 in the third direction may provide a backing for force applied to connector 310 when the components are inserted.
In an example, the different alignment tolerances may be caused by any suitable differences in components plugged into connector 310. For example, the alignment of one component may be slightly off from the center position of connector 310 in the ‘x’ direction indicated by arrow 802, the ‘y’ direction indicated by arrow 804, or a combination of both the ‘x’ and ‘y’ directions. Alignment of another component may be off from the center position of connector 310 in a direction that is different from the first component. Compressible components 606 and 608 may enable to connector 310 to move within floating connector assembly 204 as shown in FIG. 9.
Referring to FIG. 9, if a component being plugged into connector 310 is not completely aligned with the center position of the connector, compressible components 606 and 608 may enable the connector to float in any direction to allow proper alignment. For example, a force of a component being inserted within connector 310 may cause the connector to move or float in the direction of arrow 902. In this example, the force exerted by the component may cause bar 612 of float bracket 312 to compress compressible material 606 at a region 904 and bar 622 of float bracket 314 to compress compressible material 608 at a region 906.
In an example, floating connector assembly 204 may remain in the position of shown in FIG. 9 while the component is plugged into the connector 310. When the component is removed or unmated with connector 310, region 904 of compression component 606 may be uncompressed and region 906 of compression component 608 may be uncompressed. In response to the force of the component being removed, compression components 606 and 608 may reform to its original size, and connector 310 may be auto-centered within floating connector assembly 204.
While floating connector assembly 204 has been shown and described in a vertical orientation, one of ordinary skill in the art would recognize that the floating connector assembly may be positioned in any direction, such as a horizontal position, and operate as disclosed above and without varying from the scope of this disclosure.
