Cache Backup Module (CBM) for RAID Models
The Cache Backup Module (CBM), located inside the controller, consists of a battery
backup unit (BBU)
(1)
and flash backup module (FBM)
(2)
. 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

NOTE
The BBU is only charged partially when shipped. Therefore, after powering on the
system the BBU will start charging to its full capacity. It normally requires
approximately twelve hours for the battery to be fully charged. If the battery is not
fully charged after twelve hours, there may be a problem with the BBU and you
should contact your system vendor immediately. You can also check the status of the
battery module via SANWatch or the firmware (please refer to respective manuals).
