CBM (Cache Backup Module) for RAID Models
The Cache Backup Module (CBM), located inside the controller, consists of a battery
backup unit (BBU) and flash backup module (FBM). The CBM can sustain cache
memory after a power failure. The use of a CBM is highly recommended in order to
safeguard data integrity. If you are using the single controller models and would like
to install a CBM, refer to page 52,

The CBM (BBU and FBM) can be default or optional item depending on the model:
