  • Patent number: 9652340
    Abstract: A computer switching method to be performed by a computer system including a plurality of computers, a storage system, and a management computer, the plurality of computers including: a plurality of first computers and a plurality of second computers, the storage system providing a logical storage device to each of the plurality of first computers, the logical storage device including a first logical storage device which is a storage area for storing data, the computer switching method including: a step of transmitting, by the management computer, a generation request for instructing the storage system to generate a second logical storage device; a step of generating, by the management computer, change information for mapping the first logical storage device to the second logical storage device for the second computer, and transmitting a change request including the generated change information to the storage system.

  • Patent number: 8296601
    Abstract: 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.

  • Publication number: 20120192003
    Abstract: 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.
