The storage system plays an important safety protection role, and can recover the site after abnormal power failure of a power supply, namely, system configuration information before power failure and data in a write cache can fall into a system disk after power failure. The backup power pack cannot be missing and requires periodic checks to ensure the corresponding capacity, usually replacing the battery every two years, during which time the battery also requires constant observation to ensure that it can last for a predetermined time.
The requirement that the backup power packs require periodic adjustment and maintenance over long periods of use due to their natural "life" loss, leads to a number of tracking and maintenance difficulties, especially when one administrator maintains multiple storage systems or the equipment is maintained by other system administrators. Therefore, if the standby power supply group has a problem in the system, the standby power supply group cannot normally work after the system is abnormally powered off, so that the normal standby power supply process of the system is affected.
