About This Manual
This Product Manual describes how to setup, use, and maintain the VessRAID
1740s and 1840s external disk array subsystems. It also describes how to use
the built-in command-line interface (CLI), command-line utility (CLU) and
embedded Web-based Promise Array Management—Professional (WebPAM
PROe) software.
This manual includes a full table of contents, index, chapter task lists, and
numerous cross-references to help you find the specific information you are
looking for.
Also included are four levels of notices:
Note
A Note provides helpful information such as hints or alternative
ways of doing a task.
Important
An Important calls attention to an essential step or point required
to complete a task. Important items include things often missed.
Caution
A Caution informs you of possible equipment damage or loss of
data and how to avoid them.
Warning
A Warning notifies you of probable equipment damage or loss of
data, or the possibility of physical injury, and how to avoid them.

VessRAID Overview
VessRAID provides data storage solutions for applications where high
performance and data protection are required. The failure of any single drive will
not affect data integrity or accessibility of the data in a RAID protected logical
drive.
Figure 1. VessRAID front view
A defective drive may be replaced without interruption of data availability to the
host computer. If so configured, a hot spare drive will automatically replace a
failed drive, securing the fault-tolerant integrity of the logical drive. The self-
contained hardware-based RAID logical drive provides maximum performance in
a compact external chassis.

Architectural Description
The VessRAID 1740s and 1840s are Serial Attached SCSI (SAS) subsystems
suitable for Direct Attached Storage (DAS) and Expanded Storage.
The VessRAID subsystems support:
• 3.0 Gb/s SATA disk drives
• 3.0 Gb/s SAS disk drives
All VessRAID enclosures include a mid-plane, RAID controller, power supply unit,
and enclosure processor all in one cable-less chassis design. Multiple fans and
optional power supplies provide redundancy to ensure continued usage during
component failure. The RAID controller is hardware based and controls all logical
drive functions transparently to the host system. VessRAID appears to the
computer’s operating system as a standard SCSI drive or drives.
