Abstract: A passive state storage controller monitors a plurality of active state storage controllers to determine when a failure of at least one of the active state storage controllers occurs. Based on a determination of a failure, the passive state storage controller remaps storage devices to the passive state storage controller from the failed storage controller. The passive state storage controller may also remap network interfaces. The passive state storage controller retrieves a transaction log of the failed storage controller from a transaction log database, and replays transactions in the retrieved transaction log. The passive state storage controller switches to operating in an active state.

Abstract: A method, non-transitory computer readable medium, and apparatus that monitors with a passive storage controller a plurality of active storage controllers. A determination is made with the passive storage controller when a failure of one of the active storage controllers has occurred based on the monitoring. Storage device(s) previously assigned to the one of the active storage controllers are remapped to the passive storage controller. A transaction log associated with the one of the active storage controllers is retrieved with the passive storage controller from a transaction log database. Transaction(s) in the transaction log are replayed with the passive storage controller, when the failure of the one of the active storage controllers is determined to have occurred.
