Definitions
- the present invention relates to systems and methods for dissipating heat that emanates from individual electronic units within a computing device.
- An electronics rack such as a server rack
- the failure to remove this heat can result in accelerated aging and/or premature failure of the electronic units or other components in the electronics rack.
- the removal of heat can be challenging, for example, as in the prior art computing device shown in FIG. 1 .
- FIG. 1 is a perspective view of a conventional graphics processing unit (GPU) system 10 for installation in an electronics rack.
- the GPU system 10 has a front side 11 and a rear side 12 .
- the GPU system 10 also includes a first set of GPU modules 15 and a second set of GPU modules 16 , each with GPU fans (not shown) and separated by PCIe card slots 17 installed in PCIe slots (not shown) in the GPU system 10 .
- Two network cards are present at the PCIe slots 17 .
- the PCIe card slots 17 are network cards.
- the GPU system 10 further includes a PCIe baseboard 18 and a power distribution board (PDB) 19 .
- the first and second sets of GPU modules 15 and 16 are located at the front side 11 of the GPU system 10 .
- the GPU system 10 also includes fan modules 20 located opposite of the first and second sets of GPU modules 15 and 16 , i.e., at a rear side 12 of the GPU system 10 .
- the fan module 20 provides airflow 30 across the PCIe card slots 17 .
- the desktop GPU (group 15 and group 16 ) include an attached fan.
- the attached fan produces airflow 25 .
- Airflow 25 is in conflict with airflow 30 of the system fan. Because the airflow 25 of the GPU system 10 is in direct conflict with the system airflow 30 , it will negatively impact the cooling performance of the fan modules 20 .
- Some possible solutions to the conflicting airflow includes disabling the GPU fans, installing the GPU system 10 in reverse, or developing a PCIe baseboard separate from the PCIe baseboard 18 .
- these proposed solutions would require significant redesign of many components in the GPU system 10 ; introduce additional complexity into the maintenance of the GPU system 10 ; and/or would compromise the integrity of the component of the GPU system 10 . Therefore, there is a need to provide a cooling system in an electronics rack that facilitates high-heat removal without requiring significant redesign of components in a GPU system, or increasing the complexity in operating or maintaining the GPU system.
- Embodiments of the disclosure concern a computing device for cooling an electronic component.
- the computing device includes a chassis with a first end and a second end; fan modules located at the first end of the chassis; and a Peripheral Component Interconnect Express (PCIe) baseboard located at a front side of the chassis.

Abstract
Description
- The present invention relates to systems and methods for dissipating heat that emanates from individual electronic units within a computing device.
- An electronics rack, such as a server rack, can have dozens of electronic units operating, each of which is generating heat that must be removed from the electronics rack. The failure to remove this heat can result in accelerated aging and/or premature failure of the electronic units or other components in the electronics rack. However, in some types of computing devices, the removal of heat can be challenging, for example, as in the prior art computing device shown in
FIG. 1 . -
FIG. 1 is a perspective view of a conventional graphics processing unit (GPU)system 10 for installation in an electronics rack. TheGPU system 10 has afront side 11 and arear side 12. TheGPU system 10 also includes a first set ofGPU modules 15 and a second set ofGPU modules 16, each with GPU fans (not shown) and separated byPCIe card slots 17 installed in PCIe slots (not shown) in theGPU system 10. Two network cards are present at thePCIe slots 17. InFIG. 1 , thePCIe card slots 17 are network cards. TheGPU system 10 further includes aPCIe baseboard 18 and a power distribution board (PDB) 19. The first and second sets ofGPU modules front side 11 of theGPU system 10. TheGPU system 10 also includesfan modules 20 located opposite of the first and second sets ofGPU modules rear side 12 of theGPU system 10. - In
system 10, thefan module 20 providesairflow 30 across thePCIe card slots 17. However, the desktop GPU (group 15 and group 16) include an attached fan. The attached fan producesairflow 25. Airflow 25 is in conflict withairflow 30 of the system fan. Because theairflow 25 of theGPU system 10 is in direct conflict with thesystem airflow 30, it will negatively impact the cooling performance of thefan modules 20. - Some possible solutions to the conflicting airflow includes disabling the GPU fans, installing the
GPU system 10 in reverse, or developing a PCIe baseboard separate from thePCIe baseboard 18. However, these proposed solutions would require significant redesign of many components in theGPU system 10; introduce additional complexity into the maintenance of theGPU system 10; and/or would compromise the integrity of the component of theGPU system 10. Therefore, there is a need to provide a cooling system in an electronics rack that facilitates high-heat removal without requiring significant redesign of components in a GPU system, or increasing the complexity in operating or maintaining the GPU system. - Embodiments of the disclosure concern a computing device for cooling an electronic component. The computing device includes a chassis with a first end and a second end; fan modules located at the first end of the chassis; and a Peripheral Component Interconnect Express (PCIe) baseboard located at a front side of the chassis. The PCIe baseboard is configured to support placement thereof in the chassis in a first position and a second position. The second position of the PCIe baseboard is a 180-degree rotation from the first position. The PCIe baseboard includes GPU slots for installing a plurality of graphic processing units (GPUs), which include fan modules.
- The computing device can also include a power distribution board (PDB) housed between the fan modules and the PCIe baseboard. The computing device can also include power cable connectors connecting the PDB with the fan modules, the first and second set of graphic processing units, and the at least one PCIe slot. In some embodiments of the disclosure, the power cable connectors can be routed towards a center line of the PCIe baseboard, or along outer edges of the PCIe baseboard.
- The PCIe baseboard can be configured to rotate 180 degrees between the first position and the second position. In some embodiments of the disclosure, two PCIe slots can be connected to the PCIe switch via a MUX switch, a switched-capacitor resistor circuit, or a SlimSAS connector. In some embodiments of the disclosure, the first position of the PCIe baseboard is a server GPU configuration. In the server GPU configuration, the PCIe switch is located between the first and second set of graphic processing units and the fan modules.
- In some embodiments of the disclosure, the second position of the PCIe baseboard is a desktop GPU configuration. In the desktop GPU configuration, the PCIe switch can be located at the front side. The computing device can also include PCIe signal cables connecting the PCIe slot to the PCIe switch. The PCIe signal cables can be shorter in the second position of the PCIe baseboard than the first position of the PCIe baseboard, thereby improving signal integrity. The PCIe baseboard can include screw mounting holes symmetrically positioned on the PCIe baseboard to enable a transition between the first position and the second position.
- Embodiments of the disclosure also concern a PCIe baseboard located at a front side of a chassis. The PCIe baseboard is configured to support placement thereof in the chassis in a first position and a second position. The second position of the PCIe baseboard is a 180-degree rotation from the first position. The PCIe baseboard includes GPU slots for installing graphic processing units (GPUs). The GPUs each include a fan module.

The figures are not drawn to scale, and they are provided merely to illustrate the instant invention. Several aspects of the invention are described below with reference to example applications for illustration. It should be understood that numerous specific details, relationships, and methods are set forth to provide a full understanding of the invention. One having ordinary skill in the relevant art, however, will readily recognize that the invention can be practiced without one or more of the specific details, or with other methods.

- In view of the foregoing, embodiments disclosed herein are directed to GPU systems that include a PCIe board configured to be selectively positioned in a first position or a second position. This type of PCIe board allows for the installation of GPU modules, such that any GPU fans in these GPU modules can be arranged to provide airflow in the same direction as the direction required for the electronics rack the GPU system in installed in. This is discussed in greater detail with respect to
FIGS. 2A, 2B, 3A and 3B . -
FIG. 2A is a top-down view of aserver GPU system 200A, in accordance with an embodiment of the disclosure. Theserver GPU system 200A can have afront side 211 and arear side 212. Theserver GPU system 200A can include a first set ofGPU modules 215 and a second set ofGPU modules 216. In theserver GPU system 200A, the first and second sets ofGPU modules PCIe slots 217. Theserver GPU system 200A can also includefan modules 220 located opposite the first andsecond GPU modules server GPU system 200A can also have aPCIe baseboard 218 andPDB 219. - As noted above, the
PCIe baseboard 218 can be installed in first and second positions. The first position in shown inFIG. 2A . To support the multiple positions, thePCIe baseboard 218 andPDB 219 are connected using a cable methodology rather than using board-to-board connections. Therefore, as shown inFIG. 2A , theserver GPU system 200A includespower cable connectors 31 connecting thePDB 219 with thefan modules 220, the first and second sets ofGPU modules PCIe slots 217. Each GPU module of the first and second sets ofGPU modules PCIe baseboard 218. ThePCIe slots 217 can also be connected to thePCIe baseboard 218 to facilitate connection between the received network cards and other server devices (not shown). -
FIG. 2B is a top-down view of adesktop GPU system 200B, in accordance with an embodiment of the disclosure. For any components inFIG. 2B having the same reference numeral as inFIG. 2A , the description inFIG. 2A is sufficient for describing these components inFIG. 2B unless otherwise indicated below. Indesktop GPU system 200B, thePCIe baseboard 218 is provided in a second position, i.e., rotated 180 degrees relative to its position inFIG. 2A . Thus, thePCIe baseboard 218 includes a printed circuit board (PCB) (not shown) design to support use thereof in the first or second positions. - The
server GPU system 200A will keep the original GPU placement of theconventional GPU system 10. That is, the first and second sets ofGPU modules front side 211. In contrast, the rotation of thePCIe baseboard 218 will relocate the slots for the first and second sets ofGPU modules PDB 219. - In some embodiments, the board-to-board connector can include a P12V power connector and a sideband signal connector. In other embodiments, the
PDB 219 and thePCIe baseboard 218 can be connected using a cable meth to allow for design flexibility. - The
server GPU system 200A and thedesktop GPU system 200B can route thepower cable connectors 31 in the center of thePCIe baseboard 218 to the center of thePDB 219. By routing thepower cable connectors 31 in the center of thePCIe baseboard 218, thepower cable connectors 31 are easier to service. Furthermore, routing thepower cable connectors 31 in the center of thePCIe baseboard 218 improves the performance of the plurality offan modules 220, but it may overlap with otherPCIe signal cables 32. If the cable is routed outside the center of thePCIe baseboard 218, the cable can block air flow. - Other configurations can include the
power cable connectors 31 being routed along the edges of thePCIe baseboard 218 to the edges of thePDB 219. These embodiments are discussed in greater detail with respect toFIGS. 3A and 3B . -
FIG. 3A is a top-down view of aserver GPU system 300A, in accordance with an embodiment of the disclosure. Theserver GPU system 300A is the same as theGPU system 200A except for alternative routing.FIG. 3B is a top-down view of adesktop GPU system 300B, in accordance with an embodiment of the disclosure. Thedesktop GPU system 300B is the same as thedesktop GPU system 200B except alternative routing. For any components inFIGS. 3A and 3B having the same reference numeral as inFIG. 2A , the description inFIG. 2A is sufficient for describing these components inFIGS. 3A and 3B unless otherwise indicated below. Theserver GPU system 300A and thedesktop GPU system 300B route thepower cable connectors 31 along the edges of thePCIe baseboard 218 to the edges of thePDB 219. By routing thepower cable connectors 31 along the edges of thePCIe baseboard 218 to the edges of thePDB 219, thepower cable connectors 31 can be separate from thePCIe signal cables 32. However, the routing of thepower cable connectors 31 along the edges of thePCIe baseboard 218 to the edges of thePDB 219 may negatively impact the performance of thefan modules 220. Furthermore, routing thepower cable connectors 31 along the edges of thePCIe baseboard 218 to the edges of thePDB 219 may make it difficult to service the cables since will be little space to uninstall the cables in order to service them. By routing thepower cable connectors 31 along the edges of thePCIe baseboard 218, more space is provided to place more components within the center of thePCIe baseboard 218. - In both the
server GPU system 300A and thedesktop GPU system 300B, thePCIe slots 217 are placed at the front side 211 (I/O side). However, the PCIe switch (not shown) has only one downstream port to connect to thePCIe slots 217. Because the PCIe switch has a limited PCIe lane, rotating the PCIe prevents the connection of the PCIe lane from the PCIe switch and the PCIe slot. To solve this issue, some embodiments of the disclosure implement an adaptor to switch between thedifferent PCIe slots 217. Specifically, a MUX switch can be implemented to switch to thedifferent PCIe slots 217. This is discussed in more detail with respect toFIG. 5 . In alternative embodiments, a switched-capacitor resistor circuit can be connected to thePCIe slots 217. This is discussed in more detail with respect toFIG. 6 . In additional alternative embodiments, a series of SlimSAS connectors can be implemented at the PCIe switches and thePCIe slots 217. This is discussed in more detail with respect toFIG. 7 . In each of the embodiments discussed herein, space for thePCIe slots 217 is reserved at thefront side 211. -

Theright PCIe slot 417B can also be connected to thePCIe switch 421 by the PCIeinternal cable 404. - The series of PCIe switches 418, 419, 420, and 421 enable the
PCIe slots 417 to communicate with the first set of I/O ports 430 and the second set of I/O ports 431. The first set of I/O ports are connected to the PCIe switches 418 and 419. The second set of I/O ports are connected to the PCIe switches 420 and 421. The PCIe switches facilitates the electrical connection between thePCIe slots 417 and the first and second set of I/O ports O ports PCIe slots 417 are directly connected to the series of PCIe switches 418, 419, 420, and 421 in an upstream manner, thePCIe slots 417 cannot be placed at the I/O side of the GPU system.FIGS. 5-7 detail alternative topologies to be implemented in an embodiment of the present disclosure. -
