Introduction
This manual covers the DVA-16K series of RAID subsystems.
The 3U profile, SCSI-320 to SATA-II, RAID subsystem is capable of a high-performance storage
operation that has been specifically designed to meet the rapidly changing demands and
needs of today's storage networks. The RAID subsystem is rigorous and durable that can be
easily configured and operated.
Fully featured RAID redundancy provides advanced data protection and ensures that the com-
plete range of RAID levels 0, 1(0+1), 3, 5, 10, 30, 50 and JBOD are supported. Complete sys-
tem redundancy, through fully redundant data paths and hot-swappable devices ensures the
overall protection of data. A long list of sophisticated firmware functions (multi-subsystem
configuration, dedicated/ global hot-spares, battery protected disk cache, automatic back-
ground rebuild, online drive expansion, intelligent drive handling, media scan, task-scheduler,
remote and real-time subsystem monitoring, and more). Further the system guarantees the
overall availability of valuable data.
System integrators, using the RAID series, will be able to rapidly develop SCSI-320 solutions.
This will help save both development time and the associated R&D costs, providing a compet-
itive edge in the marketplace. For users, the modular nature of the series minimizes the total
management cost of building a large storage network with a RAID subsystem.
The enhanced 3U RAID storage subsystem chassis is a 3U metal chassis divided into front and
rear sections, which are respectively accessed through front and rear panels. Pre-drilled
mounting holes in the sides of the 3U RAID subsystem enclosure allow you to attach sepa-
rately purchased slide rails so that you can install the enclosure into a rack or cabinet. The
modular design of the active components facilitates their easy installation and removal. Hot-
swap mechanisms are incorporated to eliminate power surges and signal glitches that might
happen while removing or installing these modules.

Product Overview
This manual introduces the SCSI-320 to SATA-II RAID subsystem shown in Figure 2.1.
Fig. 2.1 RAID Subsystem
The RAID subsystem comes with two (2) 320MB/second SCSI (SCSI-320) host channels. This
high-density subsystem supports up to sixteen (16) hot swappable, SATA-II hard drives in a 3U
profile. The core of the subsystem is the RAID controller board with the ASIC266 and a pre-
installed 256MB DDR RAM DIMM module with support for capacities up to 1GB. The new
SCSI-320 host channel features packet protocol, and its reduction in command overhead pro-
vide increased speed without bandwidth issues.
The metal container in which the controller board is pre-installed is referred to as the "con-
troller module." The controller module is comprised of a PCB board, a rear faceplate, and a
metal canister. The controller module is accessed through the rear of the RAID subsystem. A
battery backup unit (BBU) is installed in the upper left side of the controller module when
viewed from the rear of the subsystem. The BBU is also accessible and hot swappable through
the rear panel of the RAID subsystem.
