Backup duration
Data in the cache memory is preserved against power failures. If a power
outage occurs, data in cache memory is written to drives.
When the storage system enters Cache Backup mode, the amber WARNING
LED goes on to when the system starts. This warning indicates that the
battery charge has dropped significantly and the remaining battery capacity
is not sufficient; the storage system will continue operating with the Write
Cache function disabled.
When the battery is charged, the warning indication disappears, and the
storage system continues the operation in the Write Cache function.
