Method for self optimizing value based data allocation across a multi-tier storage system

摘要

A method, apparatus, and article of manufacture are provided to support dynamic assignment of data from a continuous stream of data to one or more storage devices in a storage network. The storage network is configured with one or more tiers in a hierarchy, with at least one storage device in each tier. Similarly, the storage network is in communication with both a storage manager and a data manager. The storage manager sorts the storage devices, maintains a demand function of each device, and calculates a burn rate for each storage device. The data manager is in communication with the storage manager and assigns data from the received stream of data to at least one of the storage devices.
