Management method, device and equipment for abnormal bandwidth reduction of PCIE equipment

Abstract

The invention discloses a management method for abnormal bandwidth reduction of PCIE equipment. When the current bandwidth of the PCIE device to be tested is smaller than the maximum support bandwidth, the PCIE device to be tested can be tested. Judging whether the reason for bandwidth reduction is that the maximum support bandwidth of superior and subordinate equipment is relatively low or not; if not, judging that the PCIE equipment to be tested has an abnormal bandwidth reduction behavior (possibly has the problems of failure or loose connection and the like); the method is applied to the BIOS system, can be automatically executed during power-on self-test, does not need manual interference, and reduces the labor cost. The invention further discloses a PCIE equipment abnormal bandwidthreduction management device and equipment. The PCIE equipment abnormal bandwidth reduction management device and the PCIE equipment abnormal bandwidth reduction management equipment have the same beneficial effects as the PCIE equipment abnormal bandwidth reduction management method.

Description

technical field [0001] The present invention relates to the field of servers, in particular to a management method for abnormal bandwidth reduction of PCIE equipment, and also relates to a management device and equipment for abnormal bandwidth reduction of PCIE equipment. Background technique [0002] The server can be connected to multiple PCIE (Peripheral Component Interconnect Express, high-speed serial computer expansion bus standard) devices to achieve multiple functions, and each PCIE device can also be connected to multiple sub-devices, so each PCIE device may be connected due to loose interfaces. Or self-failure and other reasons lead to the reduction of bandwidth, but the existence of this problem is not realized in the prior art, and the abnormal bandwidth reduction behavior of the PCIE device cannot be found in time, which affects the realization of server functions and reduces work efficiency. [0003] Therefore, how to provide a solution to the above technical p...

Problems solved by technology

[0002] The server can be connected to multiple PCIE (Peripheral Component Interconnect Express, high-speed serial computer expansion bus standard) devices to achieve multiple functions, and each PCIE device can also be connected to multiple sub-devices, so each PCIE device may be connected due to loose interfaces. Or its own failure and other reasons lead to the reduction of bandwidth, but the existing technology does not realize the existence of this problem, let alone discover the abnormal bandwidth reduction behavior of PCIE devices in time, which affects the realization of server functions and reduces work efficiency.
