Creating a Separate High Performance Data Volume
As in the previous example, we’ll assume that you’ve purchased a computer with a
RAID card and four 500 GB disk drives. In this example, you want to take advantage of
RAID to create a fast data volume (for video editing, perhaps) and aren’t worried about
data protection. You’ll leave the current startup disk as is, and use a RAID 0 scheme to
create a separate volume on the remaining disks. RAID 0, which stripes data across the
drives in the RAID set, usually oers the highest performance. However, neither the
startup disk nor the data volume benet from any data protection.
To set up this example:
First, because you’re leaving the original startup disk untouched, there’s no need to
restart the computer from a dierent disc; just open RAID Utility and use the Create
RAID Set command to create a RAID 0 set using the three remaining disks. When
the RAID set appears in the left column of the RAID Utility window, select it and use
the Create Volume command to create the volume. The result is a fast 1,500 GB data
volume that’s independent of the computer’s startup disk.
Creating a New Startup Volume and Several Data Volumes
In this example, you’ll recreate a startup volume, add several data volumes, and save
some space for a future volume, all on a protected RAID set that has a spare drive
available. As in the previous examples, we’ll assume that you’ve purchased a computer
with a RAID card and four 500 GB disk drives.
To set up this example:
Because you’re going to recreate the current startup disk, you need to restart the
computer using the installation disc that comes with your computer and open RAID
Utility from the Utilities menu. Next, for the protection of the new startup disk and
the data volumes, you create a single RAID 5 set. To do so, choose the Create RAID
Set command, then choose RAID 5, select three of the four available disks, select the
“Use unassigned drives as spares” option, and click Create. Then, select the RAID set
and use the Create Volume command to create a 20 GB startup volume by changing
the default size in the volume creation dialog. Repeat the volume creation process
to add other data volumes with sizes that suit your needs. Finally, install Mac OS X or
Mac OS X Server on the new startup volume using the installation disc that comes
with your computer.
