5.1RAID configurations
The motherboard supports the following SATA RAID solutions:
•Intel® Rapid Storage Technology with RAID 0, RAID 1, RAID 10 and RAID 5 support.
•Marvell® RAID utility with RAID 0 and RAID 1 support.
•You must install Windows® XP Service Pack 3 or later versions before using Serial ATA hard disk drives. The Serial ATA RAID feature is available only if you are using Windows® XP SP3 or later versions.
•Due to Windows® XP limitation, a RAID array with the total capacity over 2TB cannot be set as a boot disk. A RAID array over 2TB can only be set as a data disk only.
•If you want to install a Windows® operating system to a hard disk drive included in a RAID set, you have to create a RAID driver disk and load the RAID driver during OS installation. Refer to section 5.2 Creating a RAID driver disk for details.
5.1.1RAID definitions
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 |
| |
configuration 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 configuration include better HDD performance, fault tolerance, and |
| |
higher storage capacity. The RAID 5 configuration 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 configuration you get all the benefits of both | 5 | |
RAID 0 and RAID 1 configurations. Use four new hard disk drives or use an existing drive | ||
Chapter | ||
and three new drives for this setup. | ||
