Background technique

At present, during the operation of the server, it is usually necessary to use the firmware data in the components to perform corresponding operations on the server. If a failure occurs during the operation of the server, such as a sudden power failure or crash, data will be lost, which in turn will affect the performance of the server. Normal use.

For example, BMC (Baseboard Manager Controller, Baseboard Management Controller), as the baseboard management system on the server, is mainly responsible for server asset information display, hardware monitoring, heat dissipation control, system configuration, remote monitoring, log collection, fault diagnosis, system maintenance, etc. important function. The server BMC with PFR (Platform Firmware Resilience, platform firmware recovery) function is divided into active area (ie active area), recovery area (ie recovery area) and staging area (ie staging area), and the BMC starts from the active area. When the active area is damaged, the server restores the active area using the recovery area. When the recovery area and the active area are damaged at the same time, the server will use the temporary storage area to restore the recovery area, and then use the recovery area to restore the active area. Therefore, the temporary storage area is the final guarantee for the BMC to start normally.
