Patent number: 8296601Abstract: A proposed fail over method for taking over task that is preformed on an active server to a backup server, even when the active server and the backup server have different hardware configuration. The method for making a backup server take over task when a fault occurs on a active server, comprises steps of acquiring configuration information on the hardware in the active server and the backup server, acquiring information relating the hardware in the backup server with the hardware in the active server, selecting a backup server to take over the task that is executed on the active server where the fault occurred, creating logical partitions on the selected backup server, and taking over the task executed on the active server logical partitions, in the logical partitions created on the selected backup server.Type: GrantFiled: September 21, 2011Date of Patent: October 23, 2012Assignee: Hitachi, LtdInventors: Keisuke Hatasaki, Masayoshi Kitamura, Yoshifumi Takamoto

Publication number: 20120192003Abstract: In order to monitor the status of a computer by monitoring the power consumption of the computer, a monitoring server (300) is equipped with: a power status database (400) in which power consumption patterns for each status of a computer (500) are stored; and a computer status detection unit (220) that determines which pattern stored in the power status database resembles the transition pattern of the measurement data obtained by the data acquisition unit (205), and then detects the status corresponding to the pattern which is deemed to be similar to the status of the computer being monitored.Type: ApplicationFiled: August 19, 2010Publication date: July 26, 2012Applicant: Hitachi, Ltd.Inventors: Kenichi Akiyama, Keisuke Hatasaki, Yoshifumi Takamoto, Masayoshi Kitamura
