Patent number: 8386830Abstract: There is disclosed a high speed switching method for a disk image delivery system fail-over. A management server sends a disk image of an active server in advance to a standby server. When receiving a report that the active server has failed, the management server judges whether or not it is possible for the standby server to perform the service of the failed active server based on service provision management server information held by the management server and if possible, instructs the standby server to perform the service of the active server. Even if the disk image delivered in advance is different from the disk image of the failed active server, switching of the service to the standby server can be performed more quickly through resetting the setting values of unique information and installing the additional pieces of software on the standby server by the management server than redelivering an appropriate disk image.Type: GrantFiled: January 4, 2011Date of Patent: February 26, 2013Assignee: Hitachi, Ltd.Inventors: Takashi Tameshige, Yoshifumi Takamoto, Keisuke Hatasaki

Patent number: 8307242Abstract: In a computer system including server apparatuses such as an active server and a standby server connected to a storage apparatus, when the active server fails, a management server changes over connection to the storage apparatus from the active server to standby server to thereby hand over operation to the standby server. The management server refers to a fail-over strategy table in which apparatus information of the server apparatuses is associated with fail-over methods to select fail-over strategy in consideration of apparatus information of the active and standby servers.Type: GrantFiled: October 20, 2011Date of Patent: November 6, 2012Assignee: Hitachi, Ltd.Inventors: Shigeki Arata, Takashi Tameshige

Publication number: 20120215924Abstract: A resource distribution method capable of lending surplus resources among a plurality of services and reducing the maintenance cost of the surplus resources is provided. Computer resources in the standby system have a dead standby state in which at least an application is not installed. A plurality of services or a plurality of users share the computer resources in the standby system. As a result, improvement of the utilization factor of idle computer resources and server integration are implemented, and the cost required to maintain the computer resources is reduced. Furthermore, load prediction is conducted as regards individual services by using past operation history. Idle computer resources secured from services having surplus and maintained are thrown in according to a result of the prediction.Type: ApplicationFiled: May 2, 2012Publication date: August 23, 2012Inventors: Takashi TAMESHIGE, Yoshifumi TAKAMOTO

Publication number: 20120131379Abstract: High availability computer system and fault correction method. If a fault occurs in the current-system physical device allocated to the current-system virtual device of the virtual server, the virtualization mechanism of the physical server configures, for the standby-system virtual device of the virtual server, the standby-system physical device, as a physical device which is used at a high priority, and the virtualization mechanism distributes the request issued from the standby-system virtual device of another virtual server to a standby-system physical device, but, when such a standby-system physical device does not exist, the virtualization mechanism distributes the request to a standby-system physical device configured for high priority usage.Type: ApplicationFiled: March 5, 2010Publication date: May 24, 2012Applicant: HITACHI, LTD.Inventors: Takashi Tameshige, Yoshifumi Takamoto, Keisuke Hatasaki

Publication number: 20100332661Abstract: Even if software resources for a physical server are changed, log information about the physical server can be accurately matched against the software resources. If the need arises to migrate business applications in a physical server (migration source), from among a plurality of physical servers, to another physical server (migration destination), a management server collects log information, which has been collected by the migration source physical server, from the migration source physical server, collects identifiers for identifying the business applications at the migration source, and records the collected identifiers in the collected log information. Subsequently, when the business applications are migrated to the migration destination physical server, the management server records the identifiers for identifying the business applications in log information about the migration destination physical server.Type: ApplicationFiled: February 19, 2010Publication date: December 30, 2010Applicant: Hitachi, Ltd.Inventor: Takashi Tameshige
