Battery Backup Module (ARC-6120BAT021)
ARC-8050 RAID storage operates using cache memory. The Battery
Backup Module is an add-on module that provides power to the
RAID storage cache memory in the event of a power failure. The
BBM monitors the write back cache on the RAID storage, and pro-
vides power to the cache memory if it contains data not yet written
to the hard drives when power failure occurs.
