ABSTRACT:
Embodiments of the invention include first storage mediums having first storage characteristics for making up a first pool of capacity of a first tier of storage, and second storage mediums having second storage characteristics for making up a second pool of capacity of a second tier of storage. Free capacity of the first and second pools is shared between the first and second tiers of storage. When the first pool has an amount of free capacity available over a reserved amount of free capacity reserved for first tier data, a first quantity of second tier data is moved from the second tier to the first tier. In exemplary embodiments of the invention, the first and second storage mediums are contained within one or more thin provisioning storage systems, and data is moved between the first and second tiers by allocating thin provisioning chunks to the data being moved.
