Chapter 1: Introduction to VessRAID
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.
