Appendix B. Intel HostRAID Setup Guidelines
After all the hardware has been installed, you must first configure Intel's IOH-36D
SATA RAID before you install the Operating System and other software drivers.
Important Note to the User:
This chapter describes RAID Configuration Instructions for the Intel IOH-36D
•
RAID Controller designed for the Windows OS.
B-1 Introduction to Serial ATA and Parallel ATA
To configure the SATA RAID functions, you must first use the Intel IOH-36D SATA
RAID Utility program to configure the RAID Level that you desire before installing
the Windows XP/2000/2003 operating system and other software drivers. (The
necessary drivers are all included in the NovaScale R423-E2 Resources CD that
came with your motherboard.) The current version of the IOH-36D SATA RAID
Utility can only support the Windows XP/2000/2003 Operating Systems.
Serial ATA (SATA)
Serial ATA (SATA) is a physical storage interface that uses a single cable with a
minimum of four wires to create a point-to-point connection between devices. It
is a serial link, which supports transfer rates up to 3.0 Gbps. Because the serial
cables used in SATA are thinner than the traditional cables used in Parallel ATA
(PATA), SATA systems have better airflow and can be installed in smaller chassis
than Parallel ATA. In addition, the cables used in PATA are limited to a length of
40cm, while Serial ATA cables can be up to one meter in length. Overall, SATA
provides better functionality than PATA.
Introduction to the Intel IOH-36D Serial RAID
Located in the South Bridge of the 5520 chipset, the I/O Controller Hub (ICH10R)
provides the I/O subsystem with access to the rest of the system. It supports
an 1-channel UltraATA/100 Bus Master IDE controller (PATA) and six Serial ATA
(SATA) ports. The IOH-36D supports the following PATA and SATA device con
