On receiving and unpacking your subsystem, check the package contents against
the included

. If any modules are missing, contact your system
vendor immediately.
RAID Controller and Interface
Each RAID controller comes with a pre-installed DDRII DIMM module. High-capacity
SATA drives are also supported by adding drive enclosures.
The traditional battery backup is replaced by an innovative CBM (Cache Backup
Module) methodology (optional feature in the single controller model), which consists
of a battery backup unit (BBU) and flash backup module (FBM). Cached data is
quickly distributed to a flash backup module with the support of a BBU in the event of
a power outage. Because of a shorter discharge time, BBU life expectancy is
extended, and data is safely kept in flash regardless of the traditional 72 hours
limitation.
The embedded firmware features intelligent algorithms, such as power-saving
modes, variable fan speeds, and exiled drive handling, making this model a greener
choice.
JBOD Controller and Interface
The enclosure is managed by expander controllers that distribute data flow to
individual disk drives and report operating status through a proprietary enclosure
