RAID support

5.1 RAID configurations

The motherboard supports the following SATA RAID solutions:

• Intel

Rapid Storage Technology with RAID 0, RAID 1, RAID 10 and RAID 5 support.

If you want to install a Windows

operating system to a hard disk drive included in a RAID

set, you have to create a RAID driver disk and load the RAID driver during OS installation.

Refer to section 5.2 Creating a RAID driver disk for details.

5.1.1 RAID definitions

RAID 0 (Data striping) optimizes two identical hard disk drives to read and write data in

parallel, interleaved stacks. Two hard disks perform the same work as a single drive but at a

sustained data transfer rate, double that of a single disk alone, thus improving data access

and storage. Use of two new identical hard disk drives is required for this setup.

RAID 1 (Data mirroring) copies and maintains an identical image of data from one drive to

a second drive. If one drive fails, the disk array management software directs all applications

to the surviving drive as it contains a complete copy of the data in the other drive. This RAID

congurationprovidesdataprotectionandincreasesfaulttolerancetotheentiresystem.Use

two new drives or use an existing drive and a new drive for this setup. The new drive must be

of the same size or larger than the existing drive.

RAID 5 stripes both data and parity information across three or more hard disk drives. Among

theadvantagesofRAID5congurationincludebetterHDDperformance,faulttolerance,and

higherstoragecapacity.TheRAID5congurationisbestsuitedfortransactionprocessing,

relational database applications, enterprise resource planning, and other business systems.

Use a minimum of three identical hard disk drives for this setup.

RAID 10 is data striping and data mirroring combined without parity (redundancy data) having

tobecalculatedandwritten.WiththeRAID10congurationyougetallthebenetsofboth

and three new drives for this setup.
