Configuring the NVRAID BIOS. Shuttle SN27P2, SN27P2 V2 | Manualzz

Configuring the NVRAID BIOS

The NVRAID BIOS setup lets you choose the RAID array type and which hard drives you want to make part of the array.

w Entering the RAID BIOS Setup

1. After rebooting your computer, wait until you see the RAID software prompting you to press F10 .

The RAID prompt appears as part of the system POST and boot process prior to loading the OS. You have a few seconds to press F10 before the window disappears.

2. Press F10 .

The NVIDIA RAID Utility— Define a New Array window appears (Figure 2.4).

Figure 2.4 NVIDIA RAID Utility

By default, RAID Mode is set to Mirroring and Striping Block is set to Optimal.

w Understanding the Define a New Array Window

Use the Define a New Array window to

• Select the RAID Mode

• Set up the Striping Block

• Specify which disks to use for the RAID Array

The SATA ports are called channels and they are associated with adapters. The first digit in the Location field defines the adapter that the port is associated with. The 2nd diigit defines the channel. (The “M” field, which used to specify Master or

Slave, is obsolete.)

If necessary, press the tab key to move from field to field until the appropriate field is highlighted.

• Selecting the RAID Mode

By default, this is set to Mirroring. To change to a different

RAID mode, press the down arrow key until the mode that you want appears in the RAID Mode box— either Mirroring, Striping,

Spanning, Stripe Mirroring or RAID 5.

• Selecting the Striping Block Size

Striping block size is given in kilobytes, and affects how data is arranged on the disk. It is recommended to leave this value at the default Optimal, which is 64KB, but the values can be between 4 KB and 128 KB (4,8,16,32,64, and 128KB).

• Assigning the Disks

The disks that you enabled from the RAID Config BIOS setup page appear in the Free Disks block. These are the drives that are available for use as RAID array disks.

To designate a free disk to be used as a RAID array disk.

1. Tab to the Free Disks section.

The first disk in the list is selected.

2. Move it from the Free Disks block to the Array Disks block by pressing the rightarrow key ( ).

The first disk in the list is moved, and the next disk in the list is selected and ready to be moved.

3. Continue pressing the right-arrow key ( ) until all the disks that you want to use as RAID array disks appear in the

Array Disks block.

Figure 2.6 illustrates the Define a New Array window after two disks have been assigned as RAID1 array disks.

w Completing the RAID BIOS Setup

1. After assigning your RAID array disks, press F7 .

The Clear disk data prompt appears.

Figure 2.7 Clear Disk Data Prompt

2. Press Y if you want to wipe out all the data from the RAID array, otherwise press N . You must choose Yes if the drives were previously used as RAID drives.

The Array List window appears, where you can review the RAID arrays that you have set up.

3. Use the arrow keys to select the array that you want to set up,then press Enter

Th e Array Detai l window appears.

Figure 2.9 Array Detail Window

The Array Detail window shows information about the array that you selected, such as Striping Block used, RAID Mode, Striping

Width, Disk Model Name, and disk capacity.

4. If you want to mark this disk as empty and wipe out all its contents then press C .

5. At the prompt, press Y to wipe out all the data, otherwise press N .

6. Press Enter again to go back to the previous window and then press [Ctrl+X] to exit the RAID setup.

Now that the RAID setup has been configured from the RAID BIOS, the next step is to configure and load NVRAID drivers under Windows, as explained in “Installing the NVIDIA RAID Software Under Windows” on page 19.
