System and method of reducing write cycles and increasing longevity of non-volatile memory in baseboard management controller (BMC)

摘要

Certain aspects direct to a baseboard management controller (BMC), which is capable of reducing write cycles and increasing longevity of its non-volatile memory. The non-volatile memory of the BMC has a file system mounted thereon. The file system defines a configuration directory storing configuration data in a binary format and migration data. In booting, the firmware of the BMC compares its version information to the version information of the configuration data. If the version information matches, the BMC uses the configuration data as is. If the version information does not match, the firmware retrieves and uses the migration data to convert the first configuration data to an initialization (INI) file in a text-based format, and then converts the generated INI file back to the binary format to update the configuration data in the configuration directory. Finally, the firmware updates the migration data in the configuration directory for future migration use.
