A monitoring server includes a transmission and reception unit that receives information from a first storage device and a second storage device by performing polling to the first storage device and the second storage device at a certain interval, and transmits the received information to the first storage device and the second storage device at next polling. The first storage device and the second storage device includes a failover processing unit that inactivates a communication port when the failover processing unit determines that abnormality has occurred in a communication path between the first storage device and the second storage device and determines, based on the polling from the monitoring server, that abnormality has occurred in a communication path between the storage device and the monitoring server.
