Abstract:
An information handling system includes first and second memories, and first, second, and third servers. The first server includes a first active application for servicing first input/output requests associated with a first disk, and for storing first state information in the first memory. 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.
