Abstract
A redundant controller storage virtualization subsystem performing host-side IO rerouting and dynamic logical media unit reassignment. In one embodiment, when a host IO request is received by a storage virtualization controller that is not a logical media unit owner of the logical media unit addressed by the IO request, the IO can be rerouted to the alternate storage virtualization controller, the logical media unit owner, to be executed. In another embodiment, the assignment of logical media unit owner can be dynamically reassigned to the receiving storage virtualization controller which was originally not the logical media unit owner such that the receiving storage virtualization controller becomes new logical media unit owner to execute the IO request. In a further embodiment, the dynamic logical media unit reassignment can be performed according to the operating condition(s) of the storage virtualization system so as to improve the performance of the storage virtualization system.
