NOTE
Upon receiving your system, check the package contents against the included
Unpacking List. If module(s) are missing, contact your system vendor immediately.
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 super capacity battery and flash backup
module combo can further preserve cache data beyond 72 hours.
The embedded firmware features intelligent algorithms, such as power-saving
modes, variable fan speeds and exiled drive handling.
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.
JBODs feature SAS interfaces that provide ease of cabling Mini-SAS connectors.
With a backplane adapting SAS, NL-SAS and SATA connectors, the system is ideal
for adding large storage capacities to a storage pool.
Power supply unit with built-in cooling module
Two cooling modules built into the power supply unit (PSU) protect the system from
overheating, and two hot-swappable PSUs provide constant power to the system.
The modular nature of the system and the easy accessibility to all major components
ensure ease of maintenance.
