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 1730i 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 1700i and 1800i Series are iSCSI 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.
