Virtual volumes overview

Virtual volumes are created from pools of storage called common provisioning groups and can be exported to hosts. Virtual volumes are the only data layer in HPE 3PAR storage virtualization that is visible to hosts.

  • Virtual volume types include base, clone, and snapshot. Learn more: Virtual volume types.

  • Provisioning. A virtual volume can be provisioned as full or thin. Learn more: Virtual volume provisioning.

  • After a virtual volume is created, its size can be increased up to a maximum size. The maximum size depends on the version of the HPE Storage OS.

  • Other key properties of virtual volumes include expiration time, retention time, RAID, space types (user, copy, admin), and compression.
