The Cache Backup Module (CBM) is an optional feature in single controller systems.

RAID Controller and Interface
Each RAID controller comes with a pre-installed DIMM module.
The traditional battery backup is replaced by an innovative Cache Backup Module
methodology (CBM) 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.
63
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
service via in-band protocols. The enclosure, along with other JBODs, connects to a
RAID system and serves as a building block of a scalable configuration.
In terms of supported protocols, the firmware supports communications with
enclosure devices, SAS/SATA disk drives and as RAID system featuring 6Gbps SAS
expansion ports.
In terms of physical connection, the SAS interface provides ease of cabling through
Mini-SAS connectors. With a backplane adapting SAS or SATA drives, the system
supports enterprise-class SAS, cost-effective SATA-II or SATA-III hard drives, and is
ideal for adding large capacity to a storage pool.
