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