Chapter 8 SATA RAID Setup
8.1 Introduction
To support demanding disk I/O, Intel ICH8DO chipset integrates six
Serial ATA controllers with software RAID 0, 1, 5, 10 capabilities.
RAID 0 stripping increases the storage performance and is designed to
speed up data transfer rates for disk-intensive applications.
RAID 1 mirroring protects valuable data that might be lost in the event of
a hard drive failure.
RAID 5 array contains three or more hard drives where the data is divided
into manageable blocks called strips. Parity is a mathematical method for
recreating data that was lost from a single drive, which increases fault-tol-
erance. The data and parity are striped across all the hard drives in the
array. The parity is striped in a rotating sequence to reduce bottlenecks
associated with the parity calculations.
RAID 10 array uses four hard drives to create a combination of RAID
levels 0 and 1. The data is striped across a two-drive array forming the
RAID 0 component. Each of the drives in the RAID 0 array is then mir-
rored by a RAID 1 component.
8.2 SATA RAID Driver and Utility Setup
The driver is in the CD’s “RAID” folder.You may go to the directory of
the CD and follow Intel's installation guide to install the driver and Util-
ity.
Note: For the detail installation guide of SATA RAID
driver & utility please check the User Guide in
the driver CD. Path: \RAID\Manual
Note: Before you install the Intel(R) Matrix Storage
Manager Please read the "readme.txt" which is
in the folder “RAID”.
