Abstract
A system for managing data includes providing at least one logical device having a table of information that maps sections of the logical device to sections of at least two storage areas. Characteristics of data associated with a one section of the logical device may be evaluated. The section of the data may moved between the at least two storage areas according to a policy and based on the characteristics of the data. The table of information is updated according to the movement of data between the at least two storage areas. Each of the at least two storage areas may correspond to a different storage tier, and each of the storage tiers may have different characteristic, such as speed of pools of storage devices within the tiers. A write target policy may be applied to store initial writes in a preferred location of the at least two storage areas.
