Chapter 8 SATA RAID Setup
8.1 Introduction
To support demanding disk I/O, Intel ICH7R chipset integrates four
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 put in the CD's path: \\Drv_RAID\ICH7R\Driver\32bit for
32bits Windows OS and path: \\ Drv_RAID\ICH7R\Driver\64bitXP for
64bits Windows OS.
You may go to the directory of the CD and follow Intel's installation
guide for install the driver and Utility.
Note: For the detail installation guide of SATA RAID
driver & utility please check the User Guide in
the driver CD. Path: \\MANUAL\SATA_RAID
Note: Operating system support list: Windows* XP,
Windows 2000, Windows Server 2003, Win-
dows XP x64 Edition, and Windows Server
2003 x64 Edition.
