Abstract
Description
Technical Field
[0001] This invention relates to the field of computer technology, and more specifically to a PCIe expansion box that uses a high-speed data cable. Background Technology
[0002] With the development of artificial intelligence technology, servers are placing increasingly higher demands on the computing power of AI accelerator cards or graphics cards, often employing multiple graphics cards in parallel to increase computing power. However, the following problems frequently arise during this process of expanding computing power.
[0003] 1. Due to the limited number of PCIe slots on existing server motherboards and the constraints of chassis space, the expansion capabilities of a single server are insufficient, making it impossible to install more graphics cards. This has caused many companies to encounter bottlenecks when expanding the AI performance of their servers.
[0004] 2. Because graphics cards generate a lot of heat when they are working, when multiple high-performance graphics cards are installed, the server will experience severe local heat buildup. If the heat cannot be dissipated effectively, the server's performance and lifespan will be affected.
[0005] 3. Due to the high power consumption of graphics cards, in a high-density deployment scenario with 10 cards, the system power may exceed 4000W. In order to ensure power supply, the server has to reduce redundant power supply modules and add series power supply modules, which increases the possibility of power failure causing system crash.
[0006] 4. The PCIe lanes on the motherboard are directly connected to the CPU, and there is a lack of PCIe switching chips, resulting in a rigid PCIe topology.
[0007] Therefore, a PCIe expansion box using high-speed data cables is proposed to solve the above problems. Summary of the Invention
[0008] (1) Technical problems to be solved
[0009] To address the aforementioned technical problems, this invention provides a PCIe expansion box employing a high-speed data cable.
[0010] (2) Technical solution
[0011] The technical solution adopted in this invention is as follows: a PCIe expansion enclosure using a high-speed data cable, comprising a metal enclosure, wherein a high-speed PCIe extension cable is provided inside the metal enclosure, and a PCIe switch expansion card is installed inside the enclosure, and the PCIe extension cable extends directly to the outside of the enclosure, with a PCIe connector on the outside; the PCIe switch expansion card has ten SFF8654 slots; SFF8654 high-speed data cables are connected to the SFF8654 slots; the other end of the SFF8654 high-speed data cable is connected to a PCIe expansion base plate; the PCIe expansion base plate is connected to an ATX power supply for power supply; all components except the PCIe extension cable are installed inside the enclosure.
[0012] Preferably, the PCIe extension cable extends outside the enclosure and can be directly connected to the host computer.
[0013] Preferably, the PCIe switch expansion card has ten SFF8654 slots.
[0014] Preferably, one end of the SFF8654 high-speed data cable is connected to the PCIe switch expansion card, and the other end is connected to the PCIe expansion baseboard.
[0015] (3) Beneficial effects
[0016] 1. Enhance scalability:
[0017] The PCIe expansion enclosure breaks through the physical space limitations of traditional server motherboards by adding extra PCIe slots (expandable to up to 10 PCIe slots). This allows users to install more AI accelerator cards or graphics cards, significantly improving the computing power of a single server.
[0018] Suitable for enterprise scenarios requiring high-density deployment, helping enterprises achieve higher computing performance without increasing the number of hardware devices.
[0019] 2. Solve the heat dissipation problem:
[0020] Because it uses an independent expansion box, it has ample space, good heat dissipation, and the heat generated by the expansion box will not affect the server itself.
[0021] 3. Improve power consumption and power management:
[0022] An independent power supply is used to power the expansion box, allowing the server itself to use a safer / redundant power supply solution.
[0023] 4. Offers flexible topology:
[0024] Traditional server motherboards have PCIe lanes directly connected to the CPU, lacking flexibility. PCIe expansion enclosures, however, are equipped with PCIe switching chips, allowing for dynamic adjustments to the connections between devices.
[0025] This design not only optimizes the data transmission path, but also improves the overall system's resource utilization and performance. Attached Figure Description
