Adaptec Embedded SATA with HostRAID Controller Driver
Adaptec's Embedded Serial ATA RAID with HostRAID controller adds RAID func-
tionality to the Serial ATA I/O controller by supporting RAID 0 (Striping) or RAID
1 (Mirroring) to enhance the industry's pioneer PCI-to-e host controller products.
RAID striping (RAID 0) can greatly improve hard disk I/O performance because
of its capability in striping data across multiple drives. RAID mirroring (RAID 1)
allows the data to be simultaneously written to two drives, so critical data is
always available even if a single hard disk fails. Due to the built-in functionality,
the X6DA8-G2 is specially designed to keep pace with the increasing perfor-
mance demands of computer systems by improving disk I/O throughput and
providing data accessibility regardless of a single disk failure. By incorporating
the Adaptec Embedded Serial ATA into the motherboard design, Supermicro's
X6DA8-G2 offers the user with the benefits of SATARAID without the high costs
associated with hardware RAID applications.
Note: For Adaptec's RAID Driver Installation Instructions, please refer to the
Adaptec RAID Controller User's Guide: "Emb_SA_RAID_UG.pdf" in the CD that
came with this motherboard. You can also download a copy of Adaptec's User's
Guide from our web site at www.supermicro.com.
The Adaptec RAID Configuration Utility is an embedded BIOS Utility,
including:
*Array Configuration Utility: Use this utility when you want to create,
configure and manage arrays.
* Disk Utilities: Use this option to format or verify disks.
To run the Adaptec RAID Configuration Utility, you will need to enable the
RAID function in the system BIOS (refer to Chapter 4 for System BIOS
Configurations), and then, press the <Ctrl> and <A> keys simultaneously
when prompted to do so during the system startup. (Refer to the previ-
ous page for detailed instructions.)
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.
Using the Adaptec RAID Configuration Utility (ARC)
The Array Configuration Utility (ACU) enables you to create, manage, and delete
arrays from the controller's BIOS, add and delete spare drives, and initialize
drives. During the system startup, press <Ctrl> and <A> key simultaneously,
and the main menu will appear.
