The second server includes a second active application for servicing second input/output requests associated with a second disk, and for storing second state information in the second memory. The third server includes first and second standby applications, and is configured to monitor the first and second active applications, to detect a failure of the first active application, to suspend the second standby application and to activate the first standby application in response to the failure of first active application.
