[0002] As the application of multi-unit services becomes more widespread, it is of utmost importance to ensure the continuous and stable operation of multi-unit servers in various environments. Therefore, higher requirements are placed on the chassis management technology of multi-unit services, requiring the whole machine management to be competent for the flexible and detailed management of each functional unit.
