4.4 RAID congurations

The motherboard comes with the Intel

ICH10R Southbridge controller that supports RAID 0,

RAID 1, RAID 10, and RAID 5 for six independent Serial ATA channels.

4.4.1 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 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

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.

Intel

Matrix Storage. The Intel

Matrix Storage technology supported by the ICH10R chip

allows you to create a RAID 0, RAID 1, RAID 5, and RAID 10* function to improve both

system performance and data safety. You can also combine two RAID sets to get higher

performance, capacity, or fault tolerance provided by the difference RAID function. For

example, RAID 0 and RAID 1 set can be created by using only two identical hard disk drives.

For Windows XP, If you want to install the system to a hard disk drive included in a RAID

set, rst copy the RAID driver from the support DVD to a USB oppy disk before installing

the operating system. Refer to section

4.5 Creating a RAID driver disk

for details.

4.4.2 Installing Serial ATA hard disks

The motherboard supports Serial ATA hard disk drives. For optimal performance, install

identical drives of the same model and capacity when creating a disk array.

To install the SATA hard disks for a RAID conguration:

1. Install the SATA hard disks into the drive bays.

2. Connect the SATA signal cables.

3. Connect a SATA power cable to the power connector on each drive.
