You can create the following types of virtual volumes:
•
Fully provisioned virtual volumes: Volume size is fixed. Creating fully provisioned virtual
volumes does not require a separate license.
•
Thinly Provisioned Virtual Volumes: Also known as Thin volumes, these volumes allocate space
on demand in small increments. Creating Thin volumes requires the HP 3PAR Thin Provisioning
Software license.
•
Physical copies: A full copy of a volume. Creating physical copies does not require a separate
license.
•
Virtual copies: A snapshot of a base volume that only records changes to the base volume.
Creating virtual copies requires the HP 3PAR Virtual Copy license.
