Chapter 1: Product introduction
1.2 Chassis
This section describes the front and rear panels of EonStor GSa 5000 Series’s rugged storage chassis.
The chassis are designed to allow installation to the rack or a cabinet.
1.2.1 Front panel
Expansion controller and interface
The expansion enclosure is managed by the 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 storage 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.
Power supply unit and cooling module
Each PSU has a built-in cooling fan to protect the system from overheating, and at the same time,
provide constant power to the system.
The cooling module is a redundant cooling type located at the front of the enclosure, which
independently ventilates the system and keep the operating procedures under optimal condition.
