Battery Backup Module (ARC6120BA-T121)
ARC-12x4 PCIe 2.0 RAID controllers operate using cache memory.
The Battery Backup Module is an add-on module that provides

power failure. The BBM monitors the write back cache on the RAID
controller, and provides power to the cache memory if it contains
data not yet written to the hard drives when power failure occurs.
