Promise Technology 15110 Architectural Description, Features and Benefits, Feature Benefit

Chapter 1: Introduction

The two standard LVD SCSI interface provides compatibility with any system that uses a SCSI interface. No vendor unique commands are required for the operation of the VTrak subsystem.

Architectural Description

The VTrak 15110 is a Direct Attached Storage (DAS) subsystem that can also function in a Storage Area Network (SAN). It consists of 15 disk drive bays, a 3U enclosure with mid-plane, RAID controller, power and cooling units, and enclosure processor all in one cable-less chassis design. Multiple fans and 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. VTrak appears to the computer’s operating system as a standard SCSI drive or drives.
