RAID conguration

6.1 Setting up RAID

The motherboard supports the following SATA RAID solutions:

• LSI MegaRAID software RAID Conguration Utility with RAID 0, RAID 1, and

RAID 10 support (for both Linux and Windows OS).

• Intel Rapid Storage Technology enterprise SCU / SATA Option ROM Utility

with RAID 0, RAID 1, RAID 10, and RAID 5 support (for Windows OS only).

6.1.1 RAID denitions

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 1E (Enhanced RAID 1) has a striped layout with each stripe unit having a

secondary (or alternate) copy stored on a different disk. You can use three or more

hard disk drives for this conguration.

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 RAID 0 and RAID 1 congurations. Use four new hard disk

drives or use an existing drive and three new drives for this setup.

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.
