Appendix D: Adaptec HostRAID Setup Guidelines
Adaptec Embedded SATA 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 effi ciency. By incorporating the Adaptec Embedded Serial ATA into the motherboard design, Supermicro's PDSMU offers the user the benefi ts of SATA RAID without the high costs associated with hardware RAID applications.
Using the Adaptec RAID Configuration 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 arrays.
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 during system boot. (Refer to the previous page for detailed instructions.)
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
