Creating Virtual Disks
Does my controller support this feature? See Supported Features .
In order to implement RAID functions, you need to create a virtual disk. A
virtual disk refers to storage created by a RAID controller from one or more
physical disks. Although a virtual disk may be created from several physical
disks, it is seen by the operating system as a single disk. For more information,
see
What Is RAID?
Before creating a virtual disk, you should be familiar with the information in
Considerations Before Creating Virtual Disks.
Storage Management provides wizards to help you create a virtual disk:
• The Create Virtual Disk Express Wizard calculates an appropriate virtual
disk layout based on the available space and controller considerations.
Using the Express Wizard, you can quickly create a virtual disk using
recommended selections. For more information, see Create Virtual Disk
Express Wizard (Step 1 of 2).
•
The Create Virtual Disk Advanced Wizard allows you to specify the read,
write, and cache policy for the virtual disk. You can also select the physical
disks and the controller connector to be used. You need a good knowledge
of RAID levels and hardware to use the Advanced Wizard. For more
information, see Create Virtual Disk Advanced Wizard (Step 1 of 4).

capacity or change its RAID level.
