1.7.2.3 Serial 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.
1.7.2.4 RAID 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).

1.7.2.5 SCSI 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.
