1.7.2.3Serial ATA RAID

The ICH6-R supports RAID (Redundant Array of Independent Drives) level 0 and RAID level 1 on the Serial ATA ports as follows:

•RAID 0 supports data striping. Two physical drives, of identical size, can be teamed together to create one logical drive. As data is written or retrieved from the logical drive, both drives operate in parallel, thus increasing the throughput.

•RAID 1 supports data mirroring. Two physical drives, of identical size, maintain duplicate sets of all data on separate disk drives. Level 1 provides the highest data reliability because two complete copies of all information are maintained.

1.7.2.4RAID Boot Configuration Overview

A RAID array can be created by using the existing Serial ATA ports, correctly configuring the BIOS, and installing drivers. The following steps are required to successfully establish a RAID configuration.

1.Enable RAID Support in BIOS.

2.Create a RAID array using the Intel Application Accelerator (IAA) utility.

3.Install the IAA RAID driver.

4.Format the RAID array.

5.Install the IAA Companion Utility (this step is optional).

1.7.2.5SCSI Hard Drive Activity LED Connector (Optional)

The SCSI hard drive activity LED connector is a 1 x 2-pin connector that allows an add-in

hard drive controller to use the same LED as the onboard IDE controller. For proper operation, this connector should be wired to the LED output of the add-in hard drive controller. The LED indicates when data is being read from, or written to, either the add-in hard drive controller or the onboard IDE controller (Parallel ATA or Serial ATA).

✏NOTE

The SCSI Hard Drive Activity LED connector is an option available only on the D925XCV board. It is not available on the D925XBC board.
