Problems solved by technology

[0002] At present, all server motherboards are designed with BMC chips. On the one hand, they can provide graphics card functions, and on the other hand, they can run the operating system to provide remote management functions. With the widespread application of BMC chips in server products, the reliability requirements for BMC are getting higher and higher. The BMC chips all run the operating system, so there is a certain probability of crashes. Once the BMC crashes, its remote management function will be invalid, and the remote control personnel will have to go to the server to reset the server motherboard. Inconvenience brings a lot of trouble to customers

Abstract

The invention discloses a method for improving the reliability of a server mainboard BMC. Based on the server with a BMC chip, the method comprises the steps that firstly, a complex programmable logicdevice (CPLD) and the BMC chip are in communication connection; then heartbeat communication is carried out, and whether the BMC is crashed or not is judged according to the heartbeat condition; whenthe BMC is crashed, a rest signal for controlling the BMC chip is sent to the BMC chip for resetting through the CPLD, and the server BMC resetting process is completed. Compared with the prior art,the method for improving the reliability of the server mainboard BMC has the advantages that a person does not need to go up to a server to reset the server BMC, use by a client is convenient, the user experience is enhanced, the crashing problem of an existing BMC chip operating system is effectively solved, high practicality is achieved, the application range is wide, and popularization is easy.

Description

technical field [0001] The invention relates to the technical field of servers, in particular to a method for improving the reliability of the BMC of the main board of the server. Background technique [0002] At present, all server motherboards are designed with BMC chips. On the one hand, they can provide graphics card functions, and on the other hand, they can run the operating system to provide remote management functions. With the widespread application of BMC chips in server products, the reliability requirements for BMC are getting higher and higher. The BMC chips all run the operating system, so there is a certain probability of crashes. Once the BMC crashes, its remote management function will be invalid, and the remote control personnel will have to go to the server to reset the server motherboard. Inconvenience brings a lot of trouble to customers. [0003] In order to solve this problem, this patent provides a method for automatically restarting the BMC once the...
