Installing CBM for RAID Models
The CBM consists of a battery backup unit (BBU) and flash backup module (FBM).
The CBM can sustain cache memory in the event of a power failure or in the
extremely unlikely event of both PSUs failing at the same time. The use of a CBM is
highly recommended in order to safeguard data integrity. The CBM is an optional
item for the single-controller model and can be purchased from your system vendor.
The CBM has to be installed on the controller before rack-mounting the system.
NOTE
Dual controller model’s BBU and FBM are pre-installed!
Dual controller systems come with the BBU pre-install in the system while the FBM
may be default or an optional item. For details, please refer to
For single controller models, the CBM (BBU + FBM) will be pre-installed for you if
you ordered it as a part of the system. If you purchase the CBM afterwards as an
upgrade component, please read and follow the instructions in this section carefully.
