Major Components
NOTE
Upon receiving your system, check the package contents against the included
Unpacking List. If module(s) are missing, please contact your system vendor
immediately.
RAID Controller and Interface
Each RAID controller comes with pre-installed DIMM module(s).
The traditional battery backup is replaced by an innovative Cache Backup Module
methodology (CBM) which consists of a super capacitor and a flash backup module
(FBM). Cached data is quickly distributed to a flash backup module for permanent
storage with the support of the super capacitor in the event of a power outage. The
advantage of a super capacitor is its very fast charging time. The super capacitor is
charged within a few minutes and available to distribute power to the controller. So
cached data can be saved immediately and permanently in flash backup module
(FBM).
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
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 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, Near-line SAS, cost-effective SATA-II or SATA-III
hard drives or SSDs, and is ideal for adding large capacity to a storage pool.
