Chapter 1: About This Guide l12
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 characteristics of input/output (I/O)
technology used by your HostRAID controller. Because SAS is a newer I/O technology, an
introduction is provided in the Appendix A.
Note:
Because this guide covers multiple Adaptec HostRAID controllers, some of the features and
functions described may not be available for your controller.
Terminology Used in this Guide
Because you can use your HostRAID controller to manage data storage in a variety of
configurations from DAS to NAS to SAN, the generic term “storage space is used to refer to
controllers 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 have multiple names. To maintain
consistency, they are represented as:
● Controller (also known as host bus adapter, board)
● Disk drive (also known as hard disk, hard drive, or hard disk drive)
● Array (also known as logical drive)
Note:
In DAS environments, Adaptec Storage Manager User’s Guide refers to arrays as logical
drives. Your RAID controller creates arrays, which your operating system and Adaptec Storage
Manager recognizes as logical drives. In NAS environments, Adaptec Storage Manager displays
both arrays and logical drives. For more information, refer to the Adaptec Storage Manager User's
Guide for Direct Attached Storage on the Adaptec Storage Manager Installation CD.
Conventions Used in This Guide
In this documentation, the term SAS-only means that the requirement, feature, or procedure is
applicable only to SAS HostRAID controllers.
The term SATA-only means that the requirement, feature, or procedure is applicable only to
SATA HostRAID controllers.
