Abstract
A method, computer program product, and system for rebalancing database table space in a hybrid storage environment of heterogeneous storage units used by a plurality of users to store associated extents. The storage units are ranked according to various performance characteristics such as IOPS rates and power consumption, and the users are ranked according to various characteristics such as whether they have subscribed to standard or premium storage subscriptions. Upon detection of a change in the relative ranking of the users or the storage units, the stored extents are mapped, characterized as standard or priority extents, and redistributed across the storage units if needed to provide higher ranked storage for priority extents and for higher ranked users.
