PROBLEM TO BE SOLVED: To provide an I/O device controller and a method for a check point/ rollback type computer capable of preventing the issue of an I/O request to a disk from being delayed. SOLUTION: Since a computer system 10 connected to hard disks 11, 12 having partitions A, B and consisting of a processor 15, a main memory 13, a control table 14, and a disk controller 16 can issue an I/O request to a secondary storage device without waiting for a check point and distribute access frequency to respective disk drives 11, 12, the performance of the system at normal processing time can be improved. |
