  • Multiple computer system and method for assigning logical computers on the same system
    Patent number: 7062674
    Abstract: High reliability is achieved against hardware failures by use of logical computers. In plural logical computers using computers comprising plural physical processors, in cases where a highly reliable system is built using the plural logical computers, the logical computers are assigned to different physical processors. During failure recovery, reduction in service is prevented by increasing processor amounts of other active logical computers of the highly reliable system.
