Chapter 6: RAID configuration
6.1 
Setting up RAID
The motherboard comes with the Intel
®
 C602 chipset that supports the following 
SATA RAID solutions:
• 
LSI MegaRAID software RAID Configuration Utility (default) with RAID 0, 
RAID 1, and RAID 10 support (for both Linux and Windows OS).
• 
Intel
®
 Rapid Storage Technology Enterprise SCU / SATA Option ROM 
Utility with RAID 0, RAID 1, RAID 10, and RAID 5 support (for Windows OS 
only).
6.1.1
RAID 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 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 RAID 0 and RAID 1 configurations. Use four new hard disk 
drives or use an existing drive and three new drives for this setup.
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.
6.1.2 
Installing hard disk drives
The motherboard supports SATA hard disk drives for RAID set configuration. For 
optimal performance, install identical drives of the same model and capacity when 
creating a disk array.
