PCE-3032/4132 User Manual 70
9.1 Introduction
To support demanding disk I/O, PCE-4132 with Intel chipset integrates Serial ATA
controllers with software RAID 0, 1, 5, 10 capabilities.
RAID 0 striping 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 man
-
ageable blocks called strips. Parity is a mathematical method for recreating data that
was lost from a single drive, which increases fault-tolerance. 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 mirrored by a RAID 1 component.
9.2 SATA RAID Driver and Utility Setup
The driver is in the CD’s "06_Intel RAID_AHCI" folder. Go to the directory and follow
Intel's installation guide to install the driver and utility.
Note!
For the detailed installation instructions for the SATA RAID driver and
utility, please check the User Guide in the driver CD.
Note! Before you install the Intel Rapid Storage Technology, please read the
"readme.txt".
