[0052] The double-path domestic CPU server can meet different needs of customers. For example, when a customer needs seven PCIE slots and also needs to support four NVMe SSD disks of the front backplane module, two MCIO X8 connectors in the first RISER card module are connected to the MCIO X4 connectors in the first MCIO connector unit and the MCIO X4 connectors in the second MCIO connector unit through high-speed cables one by one, that is, the first RISER card module can support two PCIE slots. Since the first gold finger of the second RISER card module is inserted into the first PCIE slot in the mainboard module, the second RISER card module can support three PCIE slots. Since the second gold finger of the third RISER card module is inserted into the second PCIE slot in the mainboard module, the third RISER card module can support two PCIE slots (that is, there are no two PCIE slots in the sixth PCIE slot unit connected to the MCIO X8 connectors in the fifth MCIO connector unit). In addition, two MCIO X8 connectors in the first MCIO connector unit and two MCIO X8 connectors in the second MCIO connector unit are connected to any four MCIO X8 connectors in the third MCIO connector unit through high-speed cables one by one, so that the front backplane module can support four PCIE NVMe SSD disks.

[0053] For example, when a customer needs SATA disks, two MCIO X8 connectors in the first RISER card module are connected to the MCIO X4 connectors in the first MCIO connector unit and the MCIO X4 connectors in the second MCIO connector unit through high-speed cables one by one, that is, the first RISER card module can support two PCIE slots. Since the first gold finger of the second RISER card module is inserted into the first PCIE slot in the mainboard module, the second RISER card module can support three PCIE slots. Since the second gold finger of the third RISER card module is inserted into the second PCIE slot in the mainboard module, and two MCIO X8 connectors of the third RISER card module are connected to two MCIO X8 connectors in the second MCIO connector unit through high-speed cables one by one, the third RISER card module can support three PCIE slots. Therefore, the first RISER card module, the second RISER card module and the third RISER card module can support eight PCIE cards in total, and a standard PCIE RAID card can be inserted into any one of the PCIE cards, and then the PCIE RAID card is connected to two MINISAS connectors of the front backplane module through high-speed cables, thereby supporting at least twelve SATA disks.

[0054] Scenario three: when the customer demand is satisfied with ten PCIE NVMe SSD disks under five PCIE slots, the first gold finger of the second RISER card module is plugged into the first PCIE slot in the mainboard module, so the second RISER card module can support three PCIE slots; the second gold finger of the third RISER card module is plugged into the second PCIE slot in the mainboard module, so the third RISER card module can support two PCIE slots (i.e. there are no two PCIE slots in the sixth PCIE slot unit connected with the MCIO X8 connector in the fifth MCIO connector unit); each MCIO connector in the first MCIO connector unit and each MCIO connector in the second MCIO connector unit are connected with each MCIO X8 connector in the front backboard module one by one through high-speed cables, and each MCIO X8 connector in the front backboard module can support two PCIE NVMe SSD disks, so under this kind of scenario configuration, ten PCIE NVMe SSD disks can be satisfied.

[0055] wherein Figure 6 The structure diagram of the case of the dual-path domestic CPU server is shown, Figure 6 1 in the figure indicates a storage module (the hard disk in the storage module is inserted on the front backboard module 2), 3 indicates a fan, 4 indicates a memory storage module, 9 indicates a CPU device, 5 indicates a first RISER card module, 6 indicates a second RISER card module, 8 indicates a third RISER card module, and 7 indicates a PSU power supply module.

[0056] The dual-path domestic CPU server allocates the PCIE signal resources directly output by the CPU device to the MCIO connectors and PCIE slots in the mainboard module, then connects the MCIO connectors in the mainboard module to each RISER card module or front backboard module through high-speed cables, and at the same time, connects the PCIE GEN4.0 resource signal PCIE SLOT connector pair output by the CPU to the RISER card module, so that the number of PCIE NVMe SSD disks on the front backboard module and the number of PCIE cards on the RISER card module can be flexibly switched, achieving the switching of the number of PCIE NVMe SSD disks and the number of PCIE cards on the same mainboard module, and at the same time, solving the problem that the existing technology cannot support PCIE NVMe SSD disks. In addition, by introducing a RAID controller, the SATA signal is output and connected with the M.2 connector, so that the SATA disks can be grouped into RAID.

[0057] The above-described embodiments only express several implementation manners of the application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the scope of the utility model patent. It should be pointed out that for ordinary skilled persons in the art, without departing from the concept of the application, a number of modifications and improvements can be made, which all belong to the protection scope of the application.
