Major Components
NOTE:
Upon receiving the system, check the package contents and compare them to the
Unpacking List
. If one or more of the modules are missing, please contact your system vendor.
Controller and Interface
Each system has controllers, and each controller comes with pre-installed DIMM modules. It also has a
CBM (cache backup module), a module that has a super capacitor and an FBM (flash backup module).
With the CBM, the cached data is quickly distributed to the FBM to save the data permanently with the
support of the super capacitor if power outage occurs. With the super
capacitor’s fast-charging feature, it
can distribute a fair supply of power to the controller, so the controller can save cached data to the FBM
immediately and permanently.
Also, the embedded firmware features earth-friendly and smart algorithms that you can use to customize
your
system’s hardware settings such as power-saving modes, variable fan speeds, and exiled drive
handling.
Expansion Controller and Interface
The expansion 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 expansion systems, connects to a SAN system and serves as a building
block of a scalable configuration.
For supported protocols, the firmware supports communications with enclosure devices, SAS/SATA disk
drives, and SAN system that features SAS expansion ports.
For physical connection, the SAS interface provides easy cabling routes via mini-SAS connectors. With
the backplane-adapting SAS or SATA drives, the system can support enterprise-class SAS, Nearline
SAS, and cost-effective SATA-II or SATA-III hard drives or SSDs. This connection is ideal for adding
large capacity storages to a storage pool.
Power Supply Unit/Cooling Module
There are two PSUs in the system. Each PSU is hot-swappable and is built with a fan to protect the
system from overheating while providing constant power. The modular architecture of the system and
easy accessibility to all major components provide you an easy maintenance.
