hierarchical storage management

The automated migration of data objects among storage devices, usually based on inactivity.

Hierarchical storage management (HSM) is based on the concept of a cost-performance storage hierarchy. By accepting lower access performance (higher access times), one can store objects less expensively. By automatically moving less frequently accessed objects to lower levels in the hierarchy, higher cost storage is freed for more active objects, and a better overall cost to performance ratio is achieved.
