Patent number: 9170750Abstract: A storage apparatus comprises a storage controller and multiple storage devices. The storage controller sends, to either a storage device which is a copy source of copy-target data, or a storage device which is a copy destination of the copy-target data, a copy indication showing areas of the copy source and the copy destination, and the storage device, which receives the copy indication, copies data of the copy-source area to the copy-destination area based on the copy indication without going through the storage controller.Type: GrantFiled: April 22, 2013Date of Patent: October 27, 2015Assignee: Hitachi, Ltd.Inventors: Hiroshi Abei, Koji Sonoda

Patent number: 8713266Abstract: A storage apparatus having a plurality of logical volumes includes a storage device, and a storage controller that operates each of the logical volumes as a virtual volume. A primary volume and a secondary volume are configured as a copy pair in which data in the primary volume can be copied to the secondary volume. If the primary volume receives a discard request for a unit physical storage area, the storage controller determines whether or not a unit physical storage area exists configuring the secondary volume corresponding to the unit physical storage area, which is a target of the discard request. If the unit physical storage area configuring the secondary volume exists, an instruction is transmitted to the secondary volume to discard the page or unit physical storage area assigned to the secondary volume.Type: GrantFiled: April 15, 2010Date of Patent: April 29, 2014Assignee: Hitachi, Ltd.Inventors: Michio Suetsugu, Hiroshi Abei, Haruaki Watanabe, Youichi Gotoh

Patent number: 8112362Abstract: A storage system and a license management method that can simplify license management are proposed. In a storage system in which a first storage apparatus is connected to one or a plurality of second storage apparatuses and the first storage apparatus virtualizes each of the second storage apparatuses, the first storage apparatus checks, based on this license key, which targets the license key input from the outside for setting a predetermined optional function has been issued for, and transmits the license key to the corresponding second storage apparatus when the target to which the license key has been issued is the second storage apparatus, and the second storage apparatus sets the corresponding optional function in its own storage apparatus based on the license key transmitted from the first storage apparatus.Type: GrantFiled: December 21, 2005Date of Patent: February 7, 2012Assignee: Hitachi, Ltd.Inventor: Hiroshi Abei

Publication number: 20070214294Abstract: The present invention provides a method, a system and code for backing up information on a storage system, for example, a disk system, connected to a storage area network. The host or server system off loads the task of backing up its data to the storage system that stores the data. In an exemplary embodiment a server sends an E-Copy command to a disk system. Next, the disk system finds an available back-device, for example a tape or DLT library, and then backups the information indicated in the E-Copy command to the back-up device. A user interface is provided so that one or more path groups, comprising at least a target port and an initiator port, on a disk system may be designated.Type: ApplicationFiled: May 15, 2007Publication date: September 13, 2007Applicant: Hitachi, Ltd.Inventors: Keishi Tamura, Yoshinori Okami, Hiroshi Abei, Mikito Ogata

Patent number: 7246214Abstract: Two data centers located in the vicinity are connected using a synchronous transfer copy function, and one of the data centers is coupled with a third data center disposed at a remote location by an asynchronous remote copying function. The order whereat a storage sub-system located in the vicinity has received data from a host is consistently guaranteed, and the third data center holds the data. Further, each storage sub-system includes a function whereby, during normal operation, data can be exchanged and the data update state can be obtained by the storage sub-systems located in the two data centers that do not directly engage in data transmission.Type: GrantFiled: August 4, 2004Date of Patent: July 17, 2007Assignee: Hitachi, Ltd.Inventors: Toshio Nakano, Katsunori Nakamura, Mikito Ogata, Yoshinori Okami, Seiichi Higaki, Hiroshi Abei, Shigeru Kishiro, Akira Yamamoto
