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 
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.
