INPUT/OUTPUT DEMAND INTERRUPTION SYSTEM, INPUT/OUTPUT DEMAND INTERRUPTION METHOD AND RECORDING MEDIUM HAVING INPUT/OUTPUT DEMAND INTERRUPTION PROGRAM RECODED THEREON

摘要

PROBLEM TO BE SOLVED: To provide an input/output demand interruption system for interrupting an input/output demand when operation of an OS is delayed owing to a high load. SOLUTION: In a cluster system having a shared disc and a plurality of computers, for executing mutual state monitoring by the plural computers with heart beat, each of the plurality of computers is equipped with a reception means for receiving the input/output demand to the shared disc, and an interruption means for interrupting the received input/output demand to the shared disc when a high load is applied to the OS mounted on the computer itself.
