Abstract

The invention discloses a redundancy replacement method for a QPI (Intel QuickPath Interconnect) link of a server. The method comprises the following steps: a system is switched from a working state to a quiesced state according to a received interrupt signal, wherein the interrupt signal contains information of a failed QPI link; the failed QPI link is closed according to the information of the link in the quiesced state; a route is configured, and a fault-free QPI link is constructed; the system is switched from the quiesced state to the working state. With adoption of the redundancy replacement method, redundancy replacement can be performed on the failed QPI link on the premise that the server is not shut down, and the newly constructed QPI link is used for data transmission, so that system stability is improved greatly. The invention further discloses a redundancy replacement device and equipment for the QPI link of the server and a computer readable storage medium, which all havethe same beneficial effects.

Description

technical field [0001] The present invention relates to the field of servers, in particular to a redundant replacement method for server QPI links, and also relates to a redundant replacement device, equipment and computer-readable storage medium for server QPI links. Background technique [0002] In the field of servers, the stability and reliability of system operation are very important. With more and more businesses in daily life and more and more complex, the requirements for the stability of servers are also getting higher and higher. In order to improve the stability of servers Stability, relying solely on improving the stability of a single CPU node can no longer meet people's requirements for server stability, so it is necessary to improve the overall stability of the server system. In the daily operation of the server, it is usually necessary to maintain 7*24 hours, or even 24*365 days of standby capacity to ensure the continuous operation of commercial websites, t...
