Create Virtual Disk Express Wizard (Step 1 of 2)
Does my controller support this feature? See Supported Features.
The Create Virtual Disk Express Wizard calculates an appropriate virtual
disk configuration based on the available space and controller considerations.
When using the Express Wizard, you select the RAID level and size for the
virtual disk. The wizard selects a recommended disk configuration for you
that matches your RAID and size selection.
Before creating a virtual disk, you should be familiar with the information in
Considerations Before Creating Virtual Disks. You may also want to review
Choosing RAID Levels and Concatenation.
If you want to make your own selections for the virtual disk configuration,
click Go To Advanced Wizard.

Click the radio button to select the correct RAID level.
– Depending on the controller,
Concatenated
enables you to combine
the storage capacity of several disks or to create a virtual disk using
only a single physical disk. For information on whether the controller
supports a single physical disk or two or more when using
Concatenated,
see Number of Physical Disks per Virtual Disk. Using
Concatenated
does not provide data redundancy nor does it affect
the read and write performance.
– Select
RAID 0
for striping. This selection groups n disks together as
one large virtual disk with a total capacity of n disks. Data is stored to
the disks alternately so that they are evenly distributed. Data
redundancy is not available in this mode. Read and write performance
is enhanced.
– Select
RAID 1
for mirroring disks. This selection groups two disks
together as one virtual disk with a capacity of one single disk. The data
is replicated on both disks. When a disk fails, the virtual disk
continues to function. This feature provides data redundancy and
good read performance, but slightly slower write performance. Your
system must have at least two disks to use RAID 1.
