Patent number: 8607010Abstract: In an information processing system including a computer device, and a storage device storing data used by the computer device, the region in which the data is held is managed in association with a change, over the passage of time in the performance and availability required of the data holding region. The computer device includes a storage device managing unit for managing the storage device which stores data used by the computer device. The storage device managing unit periodically monitors temporal characteristics information, and moves data, if the storage region having functional characteristics corresponding to the temporal characteristics information is different from the storage region to which the data is currently assigned.Type: GrantFiled: March 11, 2011Date of Patent: December 10, 2013Assignee: Hitachi, Ltd.Inventors: Ryoji Furuhashi, Yasunori Kaneda, Masafumi Nozawa

Patent number: 7590664Abstract: This storage system collectively manages a plurality of types of file groups reaching storage time limit, and carries out data migration spanning a plurality of storage devices. Based on the respective file information, of the respective files distributed among the respective volumes, files, whose storage time limit arrives within a prescribed period of time, are grouped together as a migration group. The storage term of the group is made to coincide with the file having the most distant storage time limit of the respective files. A first migration is carried out on the basis of the priority of the respective storage devices. A second migration is executed on the basis of the device life of the respective storage devices and the storage term of the group.Type: GrantFiled: August 17, 2005Date of Patent: September 15, 2009Assignee: Hitachi, Ltd.Inventors: Toshiki Kamohara, Eiichi Sato, Masafumi Nozawa

Patent number: 7475131Abstract: A method for displaying an access path between a virtual volume of a storage controller that has an external storage connecting function, and an external volume of an external storage system. By this method, port connection information about an access path defined between the virtual volume and the external volume is collected. A first network address for identifying an access port of the storage controller on the access path is collected. Also, a second network address for identifying an access port of the external storage system on the access path is collected. Moreover, identification information for identifying the external volume is collected. Finally, the network topology between the virtual volume and the external volume is displayed based on the port connection information, the first network address, the second network address, and the identification information.Type: GrantFiled: June 20, 2005Date of Patent: January 6, 2009Assignee: Hitachi, Ltd.Inventors: Kyosuke Achiwa, Tomoki Shoji, Masafumi Nozawa

Patent number: 7395284Abstract: There is provided a technique in which such a configuration as to include storage apparatuses on a plurality of sites can reduce a burden of operation/management of backup of data stored in the storage apparatuses. The configuration includes a information processing system on each site to be a backup target, and an information processing system for executing a backup process. Through control of a management server and a process for a backup server at a backup execution point, backup data of the data stored in the storage apparatus of the information processing system is converged into the storage apparatuses of the information processing systems by a process using a remote copying function and stored in the backup device. Then, instructions are given from the management server to the respective sites with synchronized timing, and convergence and storage of said backup data are executed by obtaining a temporal synchronization.Type: GrantFiled: January 21, 2005Date of Patent: July 1, 2008Assignee: Hitachi, Ltd.Inventors: Eiichi Sato, Masafumi Nozawa, Kyosuke Achiwa

Patent number: 7373390Abstract: An asynchronous remote copy system which can ensure the data renewal order and data integrity of the disk subsystems. The system provides for data mirroring by a main center having a gateway and a remote center having a gateway, and storage systems in each center connected to the corresponding gateway. Data is mirrored through synchronous type remote copy between volumes of the storage systems of each center. The gateway of the main center sends the renewal data to the gateway of the remote center in accordance with the order of renewal of volumes, to make the gateway of the remote center reflect the renewal data upon the volumes thereof through asynchronous type remote copy.Type: GrantFiled: October 20, 2003Date of Patent: May 13, 2008Assignee: Hitachi, Ltd.Inventors: Hideo Tabuchi, Masafumi Nozawa, Akinobu Shimada
