Appendix D: Adaptec HostRAID Setup Guidelines
The Adaptec Embedded Serial ATA with HostRAID Controller Driver
The Adaptec Embedded Serial ATA RAID Controller adds SATA/RAID functionality and performance enhancements to a motherboard. RAID striping (RAID 0) allows data to be written across multiple drives, greatly improving hard disk I/O perfor- mance. 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 Mirrors (RAID 10) provides multiple RAID 1 mirrors and a RAID 0 stripe, maximizing data security and system efficiency. By incorporating the Adaptec Embedded Serial ATA into the motherboard design, Supermicro's X7DB8/X7DBE offers the user the benefits of SATARAID without the high costs associated with hardware RAID applications.
Using the Adaptec RAID Configuration Utility (ARC)
The Adaptec RAID Configuration Utility, an embedded BIOS Utility, includes the following:
*Array Configuration Utility: Use this utility to create, configure and manage ar- rays.
* Disk Utilities: Use this option to format or verify disks.
To run the Adaptec RAID Configuration Utility, you will need to do the following:
1.Enable RAID functions in the system BIOS (refer to Chapter 4 for System BIOS Configurations).
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 Configuration Utility (ACU)
When you press <Ctrl> and <A> keys simultaneously at the prompt during system 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 (selected), press the <Delete> key to
