Create several RAID volumes
1 Verify that the Drive name matches the drive on
which to create the new volumes.
2Use the Free space slider bar to choose the
portion of the available free space that the new
volumes occupies.
You may use the keyboard to enter the portion
of free space, i.e.
xx MB, xx GB
.
3 Using the Number of volumes pull-down list,
select the number of RAID 0 volumes you wish
to create from the selected free space portion.
The number of volumes that can be created
depends on the disk free size and the space
remaining in the disk’s partition map.
4 Click on the Next button to configure the
volumes.
Specify properties
For each RAID 0 volume being created, you may
specify properties such as format type, name,
interleave and volume size. Also available in Express
Power Center v2.0, or later, is one click optimization.
This feature automatically detects and sets common
properties based on the applications that you specify.
1Use the Select Volume list box to view the
requested properties for a specific volume
being created. The properties for that volume
can then be modified.
2Use the Format list box to select the format of
the volume.
3In the Name text field, enter a name for the
volume.
4 If you are using Express Power Center v2.0, or
later, select the appropriate application in the
Application list box to automatically configure
the RAID 0 volume properties for optimal
performance. Use the Interleave list box only if
you are using Express Power Center version
older than v2.0, or if your application vendor
has recommended an interleave size different
than that displayed.
5Use the Size slider bar to adjust the size of the
volume, if necessary.
The graphical representation of the drive at the
left of the screen displays how much volume
space has been allocated and how much free
space remains.
6 Repeat the process for additional volumes.
7 Click on the Finish button.
8 Verify parameters before ATTO Express Power
Center for Mac OS X tries to create any
volumes. Click on the Back button to return to
the Create RAID 0 Volumes number of
volumes selection screen without making any
changes to your system.
9 Click on the OK button to accept your settings
and create a RAID 0 volume.
Successful completion
When the process you have chosen is
finished, a screen displays which
operations were completed or if
requested operations were not
completed.
Your desktop shows the ATTO RAID 0
volumes you have created.
Click
Quit
to end the program and use your new RAID
Level 0 volume or click
Continue
to create more
volumes.
Express Power Center RAID 0 groups are represented
on the desktop as an ATTO drive array and clipboard
labelled Express Power Center.
