Adaptec HostRAID Setup Guidelines
(For the C2SBA+II Only)
After all the hardware has been installed, you must rst congure the Adaptec
Embedded Serial ATA RAID before you install the Windows operating system.
The necessary drivers are all included on the Supermicro bootable CDs that came
packaged with your motherboard. Note 1: The following section provides information
on the Adaptec SATA RAID Driver based on the Intel ICH9R Controller.
D-1 Introduction to the Adaptec Embedded SATA RAID
Controller Driver
Serial ATA (SATA)
Serial ATA(SATA) is a physical storage interface. It 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 SATA Transfer rates up to 3.0 Gbps. Because the
serial cables used in SATA are thinner than the traditional cables used in Paral-
lel ATA(PATA), SATA systems have better airow and can be installed in smaller
chassis than Parallel ATA. In addition, the cables used in PATA can only extend
to 40cm long, while Serial ATA cables can extend up to one meter. Overall, Serial
ATA provides better functionality than Parallel ATA.
Introduction to the Intel ICH9R Controller Hub
Located in the South Bridge of the Intel G33 Chipset, the ICH9R Controller Hub
provides the I/O subsystem with access to the rest of the system. It supports the
Adaptec's rmware, which support up to six Serial ATA drives, up to two RAID
volumes and up to six drives in RAID Congurations.
* Adaptec’s SATA HostRAID Controller Firmware supports:
Drives supported
Number of RAID Volumes supported Two
To tal Drives in RAID Configurations Four
Examples of Valid RAID Configurations:
Two drives of RAID 1 + two drives of RAID 0
Two drives of RAID 1 + two drives of RAID 1
Three drives of RAID 0
Four drives of RAID 0
Examples of Invalid RAID Configurations:
Three drives of RAID 0 + two drives of RAID 1
