A PCIE expansion card and a PCIE expansion system

Abstract

The invention designs a 3 / 4 long PCIE standard card supporting PCIE expansion, which is used for PCIE signal expansion. This PCIE standard card, suitable for mainstream servers, can provide a single card maximum X48 PCIE lane for servers. The invention is used to connect PCIE standard cards, allowing the server to have greater storage capacity, computing power and network channels. In addition, the PCIE standard card supports server PCIE signal expansion, and can support the conversion of X48 to X144 PCIE Lane at most. Because there are multiple PCIE Lanes, the PCIE standard card can greatly enrich the storage, calculation and network configuration of the server. The invention also provides a PCIE expansion system, which adopts a plurality of PCIE expansion cards inserted on a motherboardX16 PCIE slot to communicate with the motherboard. Several PCIE expansion cards communicate with PCIE devices through X8 Slimline to provide a simpler and cheaper PCIE expansion solution. In the priorart which aims to mount PCIE equipment, a PCIE Box is specially designed, which will increase the cost of PCIE equipment. The cost of PCIE Box is low and the universality of PCIE equipment will be improved when PCIE equipment is designed as a standard card.

Description

technical field [0001] The invention relates to the field of server storage expansion, and specifically provides a PCIE expansion card and a PCIE expansion system. Background technique [0002] Now with the rise of applications such as AI and intelligence, more and more GPU and NVME storage are used in servers, and the use of more GPUs and NVME requires more PCIE signal channels. Generally, in the case of multiple GPUs and multiple PCIE storage media, a high-speed PCIE expansion solution is required to support fast data processing and data storage. PCIE (peripheral component interconnect express) is a high-speed serial computer expansion bus standard. In the prior art, using a total of X96 PCIE Lanes on the motherboard can theoretically support up to 6 PCIE devices such as GPUs or 24 PCIE storage devices. The application scenarios of the existing technology are relatively narrow, supporting up to 6 GPUs or 24 PCIE storage devices, and cannot meet the multi-configuration req...
