VV Summary
A virtual volume is a representation of a storage area that is not tied to any physical storage allocation. VVs are used in thin provisioning (also known as virtual provisioning) for SAN management. A virtual LUN is also sometimes called a thin LUN. HP 3PAR refers to these as virtual volumes.

# Allocated VVs
Number of virtual volumes on the array that have been mapped to a host. Links to the LUN Utilization Summary - Allocated report.
Alloc VV Capacity
Total storage capacity for the allocated virtual volumes.
# UnAllocated VVs
Number of virtual volumes that have yet to be allocated. This report links to LUN Utilization Summary - Unallocated.
