To retain data in RAID controller’s cache when the power failure, permitting any potentially dirty data in the cache to be flushed out to secondary storage when power is restored.

The batteries are recharged continuously through a trickle-charging process whenever the system power is on. The batteries protect data in a failed server for up to three or four days, depending on the size of the memory module.

Why need a BBM?

The RAID controllers are armed with a Battery Backup Module (BBM). While an Uninterruptible Power Supply (UPS) protects most servers from power fluctuations or failures, a BBM provides an additional level of protection. In the event of a power failure, a BBM supplies power to retain data in the RAID controller’s cache, thereby permitting any potentially dirty data in the cache to be flushed out to secondary storage when power is restored.
