METHOD AND APPARATUS FOR APPLYING STORAGE FUNCTIONALITY TO EACH SUBSIDIARY VOLUME

摘要

Exemplary embodiments apply storage functionality to a subsidiary volume of a logical unit group. In one aspect, a storage system comprises a plurality of storage devices to store data, and a controller operable to manage a plurality of logical volumes, each of which is a unit for setting a storage function. The controller is operable to manage a logical unit group, which is mapped to one of the logical volumes and includes an administrative logical unit and one or more subsidiary logical units. The controller is operable to manage a virtual logical unit group which includes a plurality of virtual subsidiary logical units and a virtual administrative logical unit that is mapped to the administrative logical unit, each of which is provided to one of a plurality of virtual machines of a server, at least one virtual subsidiary logical unit being mapped to the one or more subsidiary logical units.
