Abstract
In a computer system, storage controllers disposed in different data centers form a pair via a communication path between the data centers. When a communication failure occurs in the communication path between the paired storage controllers, a tie breaker takes over the data input/output from one of the storage controllers forming the pair to the other storage controller based on the statistical information of the communication characteristics of the storage controller generated by the I/O monitor, and determines failure control to stop the storage node having the one storage controller, and the storage cluster controller executes the failure control.
