Used RAID Disk
Space
This property displays how much of the physical disk space is
being used by the virtual disks on the controller. This property
is not applicable for physical disks attached to non-RAID
controllers.
In certain circumstances, the Used RAID Disk Space displays
a value of zero (0) even though a portion of the physical disk is
actually being used. This occurs when the used space is 0.005
GB or less. The algorithm for calculating the used disk space
rounds off a figure of 0.005 GB or less to 0. Used disk space
that is between 0.006 GB and 0.009 GB is rounded off to 0.01
GB.
