A replacement method, device and system for faulty pcie equipment

Abstract

The invention discloses a method for replacing faulted PCIe (Peripheral Component Interconnect Express) equipment, which comprises the following steps of when the faulted PCIe equipment is determined,a management server determining a target host server in cascade connection with the faulted PCIe equipment according to the topological information of the faulted PCIe equipment; controlling the target host server to shut down; sending a PCIe Slot power-off instruction of the faulted PCIe equipment to the BMC of a pooling server; if the faulted PCIe equipment is replaced completely, sending a PCIe Slot power-on instruction to the BMC of the pooling server; controlling the target host server to start. According to the method, when the faulted PCIe equipment is replaced, the service operation of all host servers sharing a resource pool is not influenced, and the operation and maintenance cost and risk are reduced; the invention also discloses a device and a system for replacing the faultedPCIe equipment, and a computer readable storage medium, which have the above beneficial effects.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a replacement method, device, system and computer-readable storage medium for faulty PCIe equipment. Background technique [0002] With the development of cloud computing technology, it has entered the era of big data, and the scale of data processed by data centers has grown exponentially. In the big data environment, the demand for server computing resources and storage resources is increasing day by day. Therefore, the integrated architecture supported by PCIeSwitch servers has become a new technology trend. At the hardware level, computing and storage resources such as GPUs and SSDs are integrated into a resource pool, and similar resources between different devices can be reorganized arbitrarily; The resource requirements of the front-end business are met through hardware reorganization, dynamic allocation and combination of resources to meet various requirements. ...

AI Technical Summary

Problems solved by technology

It can be seen that when the current technology replaces a faulty PCIe device, it will affect the business operation of all Host servers sharing the resource pool, increasing the cost and risk of operation and maintenance.
