Description
Technical Field
The invention relates to the technical field of server management, in particular to a method for realizing sensor information acquisition by adding a custom command support.
Background
For a server having a plurality of computing units, a System Management Controller (SMC) on a Management unit thereof needs to collect sensor information of a Baseboard Management Controller (BMC) of each computing unit while collecting sensor information of the server, so as to monitor an operation status of the entire server.
The SMC adopts the realization code of the same IPMI (Intelligent Platform Management interface) protocol stack as the BMC, so the SMC is essentially the same as the BMC, namely the SMC is an IPMI Server, and an external IPMItool or a built-in Web Server supporting an IPMI access interface is used as an IPMI Client. This design is reasonable for BMC, since in a Server with multiple computing units, BMC is a relatively pure IPMI Server.
However, for the SMC, in addition to supporting the access of the external IPMI access interface, i.e. acting as IPMI Server, it is also necessary to actively initiate the access of the BMC of each computing unit, i.e. acting as IPMI Client. In the existing solution, the SMC realizes the sensor information collection by adding a relatively independent process for accessing the BMC of each computing unit without departing from the IPMI protocol stack, and cannot make good use of the functions of the existing IPMI protocol stack and the extensibility provided by the IPMI protocol, so a new method for realizing the server sensor information collection is necessary to be provided.
Based on the problems, the invention provides a method for realizing sensor information acquisition by adding a custom command support.
