摘要: A storage apparatus for which a hierarchical data management system is adopted designed so that when receiving read request first logical area to of device in virtual volume allocated, whether or not migrate the device, second decided according an access frequency synchronization with request. When it stored should be migrated and thereof allocated volume.
