Abstract
A method and apparatus for managing data is described which includes determining the current state of a storage tier of a plurality of storage tiers within a storage system. Further, a prediction is made, using a prediction architecture comprising at least one predetermined variable, of the utilities of future expected states for at least two of a plurality of storage tiers involved with a data operation, wherein a future expected state of a corresponding storage tier is based on conditions expected to occur following the completion of the data operation. Finally, the data operation is performed if the predicted utility of the future expected state associated with the at least two of a plurality of storage tiers is more beneficial than the utility of the current state.
