System managing a plurality of virtual volumes and a virtual volume management method for the system
Patent number: 8122214Abstract: This invention provides a control technique of a data processing system, in which functions of a highly-functional high-performance storage system are achieved in an inexpensive storage system so as to effectively use the existing system and reduce the cost of its entire system. This system has a RAID system, an external subsystem, a management server, a management client and the like. The management server includes an information management table for storing mapping information of the RAID system and the external subsystem. When performing copy process, the pair creation in which a logical volume of the RAID system is set as a primary volume of copy source and a logical volume of a mapping object of the RAID system mapped from the logical volume of the external subsystem is set as a secondary volume of copy destination is executed from the management client by using the information management table.Type: GrantFiled: October 20, 2010Date of Patent: February 21, 2012Assignee: Hitachi, Ltd.Inventor: Shoko Umemura -

Publication number: 20100131469Abstract: A storage management device is interposed between a file management device and a plurality of storage resources which are possessed by a storage system. The storage management device receives a file access request from the file management device, and, in response to the file access request, accesses any one of files stored in any one of the plurality of storage resources possessed by the storage system. And the storage management device includes a file copy module and a deletion processing module. The file copy module performs file copy processing in which files are copied between the storage resources. And if the result of the file copy processing is that, among the plurality of storage resources, there is some storage resource which can be deleted, which is a storage resource upon which only files which can be deleted are stored, the deletion processing module performs deletion processing of that storage resource which can be deleted.Type: ApplicationFiled: February 2, 2009Publication date: May 27, 2010Inventor: Shoko Umemura

Patent number: 7725650Abstract: A storage system where storage areas are provided to host systems using a conventional AOU technique, the storage system being able to reduce power consumption by the storage resources allocated to pools and prevent the shortening of the life expectancy of the storage resources. In the storage system, data storage devices defined as belonging to the pools are allocated to virtual volumes. Allocation is performed in accordance with access by the hosts. The data storage devices are powered off before being allocated to the virtual volumes and powered on after being allocated.Type: GrantFiled: June 21, 2006Date of Patent: May 25, 2010Assignee: Hitachi, Ltd.Inventors: Shoko Umemura, Eiichi Sato
