Fig. 1 is a schematic diagram of a multi-card GPU server according to the present utility model, as shown in fig. 1, which includes a PCIe riser (interface expansion) card 1, an slimmesas cable 2, a four-card GPU chassis 3, wherein,

the PCIe riser card 1 comprises a riser card with PCIe standard interfaces, PCIe data complete links are led out from a main board through the riser card, a PCIe riser card is respectively arranged on the front side and the back side of each main board, each PCIe riser card comprises two SlimLine SFF-8654 interfaces, and data are connected with a four-card GPU base plate 3 through a SlimSAS cable 2.

In this embodiment, to ensure the integrity of the data bandwidth, 16 data channels are required for a complete graphics card PCIe link, and at most 8 data channels can be walked through by a SlimLine SFF-8654 interface.

Specifically, the four-card GPU base plate 3 can be provided with 4 display cards simultaneously, and provides power supply requirements of each display card, all display cards are connected with the PCIe interface of the main board in a 1-to-1 data mode, and the PCIe interface of the main board is free from the restriction of the GPU base plate through the bandwidth of the display cards.

In this embodiment, by decoupling the direct connection relationship between the GPU and the motherboard, only enough space is reserved on the GPU chassis, so that four super-high and super-thick commercial graphics cards can be simultaneously mounted on the standard width chassis. Compared with a special graphic card, the commercial graphic card has lower cost, sufficient market sources and smaller restriction.
