Product Introduction
This chapter introduces the look and feel of the PS 2000 All-Flash Series system, the features,
and the supported components.
Overview
This manual introduces the PS 2000 All-Flash Series system that supports 3 Gbps, and 12
Gbps SAS and Near-line SAS, and SATA SSDs. This system is designed to utilize 2.5” SSDs.
Drive capacity can be expanded by attaching expansion hard drive enclosures.

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
The 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 cache 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, 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.
