Battery Backup Module (ARC-6120-BAT-
xxx)
The SAS RAID controller operates using cache memory. The Bat-
tery Backup Module is an add-on module that provides power to
the SAS RAID controller cache memory in the event of a power fail-
ure. The Battery Backup Module monitors the write back cache on
the SAS RAID controller, and provides power to the cache memory
if it contains data not yet written to the hard drives when power
failure occurs.
