Dell EMC Server Administrator Storage Management 9.1

RAID Controller Batteries

Some RAID controllers have batteries. If the controller has a battery, Storage Management displays the battery under the controller object in the tree view.

If there is a power outage, the controller battery preserves data that is in the volatile cache memory (SRAM) but not yet written to disk. The battery is designed to provide a minimum backup of 24 hours.

When a RAID controller is first installed in a server, the battery may need charging.

For information on alert messages, see the Server Administrator Messages Reference Guide.
