Problems solved by technology

[0003] In the prior art, the PCIE signal distribution of the OCP standard card and the OCPmultihost card is realized by using a riser card and a cable (cable). In this way, the cost of the riser card and the cable needs to be additionally increased; In addition, the switch between the OCP standard card and the OCP multihost card needs to be completed by manually plugging and unplugging the cable to realize the distribution of PCIE signals. The cable plug interface is easily damaged, and the cable is prone to entanglement, which increases the difficulty of server maintenance.

Abstract

The invention discloses a server and method for automatically distributing PCIE signals, the server comprises a signal switching chip, a complex programmable logic chip, an OCP card and a plurality of CPUs, and the type of the OCP card comprises an OCP standard card and an OCP multihost card; wherein the complex programmable logic chip is used for judging the type of the currently accessed OCP card; and the signal switching chip is used for switching an internal logic interface distribution mode according to the type of the OCP card sent by the complex programmable logic chip, and distributing a PCIE signal from the CPU to the OCP standard card or the OCP multihost card according to the switched internal logic interface distribution mode. According to the server and the method for automatically distributing the PCIE signals disclosed by the invention, the cost of an adapter card and a cable does not need to be additionally increased, and the maintenance difficulty of the server is reduced.

Description

technical field [0001] The embodiment of the present application relates to the technical field of servers, and in particular to a server and a method for automatically distributing PCIE signals. Background technique [0002] In order to meet different application scenarios, the multi-channel server usually needs to support an OCP (Open Computer Project, Open Computing Project) standard card or an OCP multihost (multi-host) card. OCP standard card includes a NIC (network interface controller, network interface controller), PCIE (peripheral component interconnect express, high-speed serial computer expansion bus standard) signal can come from a CPU (Central Processing Unit, central processing unit); OCP multihost card internal Including multiple NICs, PCIE signals can come from multiple CPUs. Since the PCIE signal distribution methods of the OCP standard card and the OCP multihost card are different, the distribution needs to be made according to the type of the OCP card. ...
