Technical Brief: RAID

page 4

1. Introduction

This Technical Brief assumes that the reader has a basic understand-
ing of RAID (Redundant Array of Independent/Inexpensive Disks)
and the benefits of securing data on multiple disk arrays. For those
interested in learning more about RAID, please visit LaCie’s

Tech-

nology Page

and read our detailed

White Paper

.

IMPORTANT INFO:

This Technical Brief offers a description of

Windows® Storage Server 2008 RAID implementation on the 5big
Storage Server. The information regarding RAID does not apply to
the 12big Rack Network since it includes a hardware RAID solution.

2. Administrator

In order to review, confirm, or redefine the software settings on your
LaCie professional server, you must have Administrative rights to the
device.
