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.
