Server and server mainboard

Abstract

The invention discloses a server mainboard. The server mainboard comprises a server mainboard main body and a CPU, wherein the CPU is provided with N groups of PCIE interfaces, each group of PCIE interfaces is the link width of X8, and each group of PCIE interfaces is provided with a target interface which corresponds to the group of PCIE interfaces and is used for outputting information representing the type of a device connected with the PCIE interface to the CPU; the N groups of PCIE interfaces are respectively connected with the N connectors; for any connector, the connector is allowed tobe connected with the BP, the connector is allowed to be connected with the PCIE card of the X8, and the connector and the connector adjacent to the connector are allowed to be connected with the PCIEcard of the X16 together. By applying the server mainboard of the invention, the flexibility of the PCIE link width of the server mainboard is improved, and the PCIE device connected with the CPU canbe flexibly configured. The invention further provides a server which has a corresponding effect.

Description

technical field [0001] The invention relates to the technical field of computer design, in particular to a server and a server motherboard. Background technique [0002] With the continuous development of computer technology, in order to reduce or even get rid of domestic dependence on Intel, AMD and other processors, the development of CPU and motherboards has also received more and more attention. [0003] However, some current CPU motherboards are simple in design, and the Link Width of PCIE is fixed, so automatic and flexible configuration cannot be performed according to different PCIE devices. For example figure 1 It is a schematic diagram of the current Haiguang 7000 public version server motherboard design scheme. It can be seen that the PCIE link width has been fixed during design and development, and the application scenarios are limited and not flexible enough. [0004] To sum up, how to effectively improve the flexibility of the PCIE link width of the server ma...

[0003] However, the design of some current CPU motherboards is simple, and the Link Width of PCIE is fixed, so it cannot be automatically and flexibly configured according to different PCIE devices

E.g figure 1 It is a schematic diagram of the current Haiguang 7000 public version server motherboard design scheme. It can be seen that the PCIE link width has been fixed during design and development, and the application scenarios are limited and not flexible enough.
