Abstract
The present disclosure relates to a data storage device having a hypervolume accessible by a plurality of servers operating on two or more data storage systems, a first physical volume, associated with the hypervolume, located at a first data storage system, and a second physical volume, associated with the hypervolume, located at a second storage system. The hypervolume directs input/output (I/O) from the servers to a primary physical volume comprising either the first or second physical volume, and the primary physical volume may be changed, transparently to the servers, to the other of the first or second physical volume. The present disclosure, in another embodiment, relates to a method for moving operation of a storage device from one data storage location to a second data storage location. A hypervolume is used to redirect input/output (I/O) from the a plurality of servers from the one physical volume to another.
