Abstract
Managing data includes providing at least one logical device that maps sections of the logical device to sections of at least two physical storage areas, where the at least two physical storage areas have different physical storage properties, evaluating characteristics of data associated with at least one of the sections of the logical device, where at least some of the characteristics depend upon predictions as a function of time of future data usage based on past data usage and on heuristic values, and moving the at least one of the sections of the logical device between the at least two storage areas from a first location to a second location according to the characteristics of the data. Each of the at least two physical storage areas may correspond to a different storage tier. Predictions of future data usage may be provided by a state space model.
