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, Near-line
SAS, and cost-effective SATA-II or SATA-III SSDs. This connection is ideal for adding large capacity
storages to a storage pool.
Power supply unit/cooling module
There are two PSU/cooling modules in the system. Each PSU/cooling module 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.
