ABSTRACT:
A dynamic storage system allows storage servers to access spare data storage devices should an associated data storage device fail or become inaccessible. A sparing server receives requests for spare data storage devices from storage servers and allocates spare data storage devices, establishing and maintaining a communication channel between the storage server and the spare data storage device. Once the associated data storage device is returned to service, the spare data storage device is released by the storage server and returned to a spare storage pool by the sparing server.
