6-2 Chapter 6: RAID conguration
6.1 Setting up RAID
The motherboard comes with the Intel
®
ICH10R southbridge controller that
supports the following SATA RAID solutions:
LSIMegaRAIDsoftwareRAIDCongurationUtility
(default) with RAID 0
and RAID 1 support (for both Linux and Windows OS).
Intel Matrix Storage Manager
with RAID 0, RAID 1, and RAID 5 support (for
Windows OS only).
6.1.1 RAIDdenitions
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 conguration 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 conguration include better HDD
performance, fault tolerance, and higher storage capacity. The RAID 5 conguration
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 conguration. For
optimal performance, install identical drives of the same model and capacity when
creating a disk array.
See section
2.4 Hard disk drives
for SATA hard disk drive installation.
