Patent number: 9342456Abstract: A non-transitory computer readable storage medium that stores a storage control program causing a computer to execute a control process of a storage including a first storage device with first access speed, and a second storage device with second access speed that is slower than the first access speed, includes monitoring access frequency to data in the first and second storage devices; relocating data, the access frequency of which exceeds a first reference value, in the second storage device, to the first storage device; and conducting a overload processing of retaining, in the cache memory, at least a part of the data in the second storage device when the second storage device is in an overload state. the access frequency monitoring is executed in a state where the partial data is retained in the cache memory, and the relocating is executed based on the access frequency to the partial data.Type: GrantFiled: March 6, 2014Date of Patent: May 17, 2016Assignee: FUJITSU LIMITEDInventors: Eiichi Kobayashi, Sachiko Terai, Chunyou Shao, Pierre Ribault

Patent number: 8380823Abstract: Device component information (physical information, logical information) on each device such as a host computer, a switch, and storage on the SAN is acquired via an LAN 9. Element information is created from the acquired device component information. According to the element information, a link between element information is created. Furthermore, when a plurality of links are established for an element, information is stored in advance so as to be used for selecting one of the links. Thus, each element stored the minimum information for routing and it becomes possible to search an associated element more effectively.Type: GrantFiled: September 27, 2005Date of Patent: February 19, 2013Assignee: Fujitsu LimitedInventors: Sachiko Terai, Sawao Iwatani, Shigeru Honmura, Hideyuki Tanaka

Patent number: 7971089Abstract: When a server RM detects a failure in an operating server, a system resource manager selects a substitute server from a pool of a server domain to which a failed server belongs, based on information in a system resource DB, disconnects the failed server from a business network and a storage sub group and moves the failed server to a pool, and permits the substitute server to access a storage group to which the failed server had an access and to connect to the business network to which the failed server was connected, to boot up the substitute server from a SAN.Type: GrantFiled: April 17, 2007Date of Patent: June 28, 2011Assignee: Fujitsu LimitedInventors: Shigehiro Yoshikawa, Yoshinobu Hibi, Hideyuki Tanaka, Masayuki Naitou, Satoshi Iyoda, Sachiko Terai, Sawao Iwatani, Yuji Nomura

Patent number: 7752295Abstract: When information on a device such as a server, storage, and an FC switch constituting a SNA system is input, these devices are displayed and arranged properly on a screen (S1, S2). When information on a physical path is input by a designer by using this display screen, a virtual SAN system in which the devices are connected by a fiber channel is displayed on the screen (S3). Furthermore, when information on an access path is input by the designer by using the construction image, the access path is additionally displayed on the construction image of the virtual SAN system (S5). Since the construction image of the virtual SAN system is displayed on the screen, the designer can easily create a design drawing while visually checking the SAN system. This can reduce the work load and time required for construction of the SAN system.Type: GrantFiled: September 30, 2004Date of Patent: July 6, 2010Assignee: Fujitsu LimitedInventors: Sachiko Terai, Sawao Iwatani, Hideyuki Tanaka, Shigeru Honmura, Noriaki Matsuzaki, Yasushi Kisimoto, Fumikazu Fujimoto, Kenichi Matsumoto, Hiroki Ohashi, Hideaki Hasegawa, Keiko Usunaga, Soichi Takeuchi

Publication number: 20070233952Abstract: A computer program, method, and apparatus that can easily perform setting taken into account the reliability of and the load on a disk array. A logical volume requirement acquisition section acquires a logical volume requirement. An applied technique determination section then determines an applied technique for improving at least one of reliability and processing speed according to the logical volume requirement. A logical volume setting section then outputs instructions to generate a logical volume which is made up of a plurality of disk drives and which is used for realizing the determined applied technique and instructions to set an environment in which a server accesses the logical volume by using the applied technique to the server and a disk array.Type: ApplicationFiled: March 29, 2007Publication date: October 4, 2007Applicant: Fujitsu LimitedInventors: Hideyuki Tanaka, Sachiko Terai, Sawao Iwatani, Fumikazu Fujimoto, Shinji Hamaguchi, Hideaki Hasegawa, Noriaki Matsuzaki, Hiroki Ohashi, Keiko Usunaga, Souichi Takeuchi

Patent number: 7203770Abstract: On the screen of a computer, a server, a storage device and an FC switch are virtually provided and these devices are connected by a physical path. When an instance is generated in the server and the instance is dragged/dropped into the storage device, both the command to establish a multipath and the command to acquire a data area corresponding to the instance in the storage device are automatically generated. These commands are transmitted to the respective devices of an actually configured storage system.Type: GrantFiled: February 24, 2004Date of Patent: April 10, 2007Assignee: Fujitsu LimitedInventors: Sachiko Terai, Sawao Iwatani, Hideyuki Tanaka
