Integrated Striping - Dell Precision Workstation 450 User Manual

Integrated Striping

Your Dell Precision 650 computer supports integrated striping for a minimum of two hard drives to a maximum of four hard drives on the Integrated Ultra320
SCSI channel. Integrated striping writes data across multiple hard drives rather than writing to one hard drive by partitioning each hard drive's storage space
into stripes. The stripe volume can be created and deleted through a SCSI BIOS configuration utility.
Creating a Stripe Volume
NOTICE: Creating a stripe volume deletes all information that is currently on your hard drives. Save all data before you begin this procedure.
1. Press <Ctrl><a> during system start-up when the following message appears: Press Cntl-A to start LSI Logic Configuration Utility.
NOTE: Key combinations for the utility are listed at the bottom of the configuration screen.
2. Select the drive controller and press <Enter>.
3. Use the arrow keys to select Add RAID Array and press <Enter>.
4. Use the <+> key to select YES for each drive that you want to be part of a stripe volume. Use the <-> key to select NO for each drive that you do not
want to be part of a stripe volume.
NOTE: Multiple warning screens may appear if you have a valid partition on the drives selected or if the drives selected to be part of the stripe are
different sizes.
5. Press <F3> to save the changes.
6. Press any key to continue.
7. If you do not want to create the stripe volume, select Discard Changes Then Exit this Menu.

8. Press <Esc>, exit the configuration utility, and then press <Enter>.
The stripe volume can be used as a boot volume or as a data volume. For more information, see your operating system documentation.
NOTE: If you choose unequal drive sizes to be part of the stripe volume, the available size of the stripe volume is equal to the number of drives in the
volume multiplied by the smallest drive size in the volume. The unused space in the larger drive is unusable.
