the selected
JBOD
,
SAFE
,
FAST
, or
BIG
storage policy. The SAFE33 and SAFE50
storage policies are not available in the Advanced Configuration Wizard (although the
equivalent SAFE and BIG volumes can be configured manually).
Using the Advanced Configuration Wizard, you can configure up to two volumes with the
same or different storage policies on the two hard drives. The following configuration
options are possible, where each of the two volumes is allocated some portion of the total
system capacity:
•
Two SAFE volumes that are mirrored from the first hard drive to the second drive.
•
Two FAST volumes that are striped across the two hard drives.
•
Two BIG volumes that are spread across the two hard drives (part of each drive is
concatenated, or added to, a portion of the second drive).
•
One
FAST
volume that is striped across the two hard drives and one
BIG
volume
that is allocated the remaining capacity on both drives. The reversed
configuration—one
BIG
volume and one
FAST
volume—is also possible.
•
One
FAST
volume that is striped across the two hard drives and one
SAFE
volume
that is allocated the remaining capacity (split between the volume and its mirror
twin). The reverse configuration (one
SAFE
volume and one
FAST
volume) is
also possible.
•
One
BIG
volume that is spread across the two hard drives (part of each drive is
concatenated, or added to, a portion of the second drive) and one
SAFE
volume
that is allocated the remaining capacity (split between the volume and its mirror
twin).
Note: You cannot combine the JBOD and SAFE storage policies. A JBOD volume consumes one
entire drive and a SAFE volume requires one drive for the volume and a second drive for its mirror
twin. You also cannot combine the JBOD and FAST storage policies. JBOD consumes an entire
drive and a FAST volume requires two drives for striping.
If multiple volumes are created for a subordinate node in a cascaded configuration, only the first
volume will be visible to the node above it. Similarly, if multiple volumes are created on a
standalone Storage Processor or the top-level node of a cascaded configuration with a SATA
host connection that is not PM-aware, only the first volume will be visible to the host.
A Look at the Advanced Configuration Wizard
The Advanced Configuration Wizard is an extension of Basic mode that allows you to create
up to two volumes (virtual drives) on each physical hard drive.
