The Adaptec Embedded Serial ATA with HostRAID Controller
Driver
The Adaptec Embedded Serial ATA RAID Controller adds SATA/RAID functional-
ity and performance enhancements to a motherboard. RAID striping (RAID 0)
allows data to be written across multiple drives, greatly improving hard disk I/O
performance. RAID mirroring (RAID 1) allows data to be simultaneously written to
two drives, improving data security even if a single hard disk fails. A Stripe of Mir-
rors (RAID 10) provides multiple RAID 1 mirrors and a RAID 0 stripe, maximizing
data security and system effi ciency. By incorporating the Adaptec Embedded Se-
rial ATA into the motherboard design, Supermicro's X7DBX-8/X7DBX-i offers the
user the benefi ts of SATARAID without the high costs associated with hardware
RAID applications.
Using the Adaptec RAID Confi guration Utility (ARC)
The Adaptec RAID Confi guration Utility, an embedded BIOS Utility, includes the
following:
*Array Confi guration Utility: Use this utility to create, confi gure and manage ar-
rays.
* Disk Utilities: Use this option to format or verify disks.
To run the Adaptec RAID Confi guration Utility, you will need to do the following:
1. Enable RAID functions in the system BIOS (refer to Chapter 4 for System
BIOS Confi gurations).
2. Press the <Ctrl> and <A> keys simultaneously when prompted to do so during
system boot. (Refer to the previous page for detailed instructions.)
A. Using the Array Confi guration Utility (ACU)
When you press <Ctrl> and <A> keys simultaneously at the prompt during sys-
tem bootup, the main menu will appear.
(*Note: To select an option, use the arrow keys to highlight the item and then
press the <Enter> key to select it. To return to the previous menu, press the
<ESC> key. Press the <Insert> key to select a drive. When a drive is highlighted
