The feature enables the following functions for the storage type:
• Easy Tier application
• Easy Tier heat map transfer
• The capability to migrate volumes for logical volumes

• The dynamic extent relocation with an Easy Tier managed extent pool
Operating environment license
The operating environment model and features establish the extent (capacity) that is authorized to use
the product operating environment.
To determine the operating environment license support function, see “Machine types overview” on page

Thin provisioning
Thin provisioning defines logical volume sizes that are larger than the usable capacity installed on the
system. The volume allocates capacity on an as-needed basis as a result of host-write actions.
The thin provisioning feature enables the creation of extent space efficient logical volumes. Extent space
efficient volumes are supported for FB and CKD volumes and are supported for all Copy Services
functionality, including FlashCopy targets where they provide a space efficient FlashCopy capability.
