HP dx5150 RAID Installation

and Setup Guide

Introduction

RAID (Redundant Array of Independent Disks) technology
manages multiple disk drives to enhance I/O performance and to
provide redundancy in order to withstand the failure of any
individual member without loss of data.

SATARAID™ provides two RAID Set types: Striped Set (RAID

0) and Mirrored Set (RAID 1).

Disk Mirroring (RAID 1)

Disk mirroring creates an identical twin for a selected disk by
writing the data simultaneously to two disks. This redundancy
provides protection from a single disk failure. If a read failure
occurs on one drive, the system then reads the data from the other
drive.

Disk Striping (RAID 0)

Striping is a performance-oriented, non-redundant data mapping
technique. It does not provide fault tolerance. With modern
SATA and ATA bus mastering technology, multiple I/O
operations can be performed in parallel, enhancing performance.
Striping arrays use multiple disks to form a larger virtual disk.
