Figure 10-13 shows the Volumes window with a list of volumes, which are created in DRP. 
Only Capacity (which is virtual capacity that is available to a host) is shown. Real capacity, 
Used capacity, and Compression savings show as Not Applicable for volumes with capacity 
savings. Only fully allocated volumes display those parameters.
