Chapter 1: About This Guide ● 11
What You Need to Know Before You Begin
You should be familiar with computer hardware, data storage, Redundant Array of
Independent Disks (RAID) technology, and the input/output (I/O) technology—SAS—used
by your HostRAID controller. (For an introduction to SAS, see page 52.)
You should also be familiar with Direct Attached Storage (DAS) and Storage Area Network
(SAN) concepts and technology.
Terminology Used in this Guide
Because you can use your HostRAID controller to manage data storage in a variety of
configurations from DAS to SAN, the generic term “storage space” is used to refer to
controller(s) and disk drives being managed with Adaptec Storage Manager
TM
or the other
utilities described in this Guide.
Many of the terms and concepts referred to in this Guide are known to computer users by
multiple names. This Guide uses these terms:
● Controller (also known as adapter, board, or card)
● Disk drive (also known as hard disk, hard drive, or hard disk drive)
● Array (also known as a container or logical drive)
Note:
The Adaptec Storage Manager User’s Guide refers to arrays as logical drives. Why?
Your HostRAID controller creates arrays, which your operating system (and Adaptec Storage
Manager) recognizes as logical drives.
