COOPERATIVE TIERING

Various systems and methods for cooperative tiering between an application and a storage device. One method can include receiving information from the application where the information identifies a storage object and identifies a location in a storage device. The location identifies one or more tiers of a plurality of tiers included in the storage device, and the storage object is assigned to the one or more tiers. The method also involves detecting whether the storage object is stored in the one or more tiers. If not, the storage device copies the storage object to the identified location. The information can also include an instruction by the application to move the storage object from a first tier to a second tier.
