Product Description NOTE Many Serial ATA drives use new low-voltage power connectors and require adaptors or power supplies equipped with low-voltage power connectors. For more information, see: http://www.serialata.org/ For information about The location of the Serial ATA IDE connectors Refer to Figure 16, page 52 1.5.2.3 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. 1.5.2.4 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).

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.
1.5.2.4
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).
