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.

Abstract: A method, non-transitory computer readable medium and host device that monitors an active virtual storage controller. A determination of when a failure of the active virtual storage controller has occurred is made based on the monitoring. When the failure of the active virtual storage controller is determined to have occurred, one or more storage devices previously assigned to the active virtual storage controller are remapped to a passive virtual storage controller and one or more transactions in a transaction log are replayed.

Abstract: A system and method of testing, during development, the operation of a clustered storage server system and its associated storage operating system. The system includes at least one host computer having a host operating system, and at least one virtual computer having a simulated storage operating system, at least one simulated disk, a simulated NVRAM, and a simulated flashcard within a guest operating system hosted by the host operating system. The simulated storage operating system represents an actual storage operating system. Facilities of the simulated storage operating system including the simulated disk, the simulated NVRAM, and the simulated flashcard are mapped onto corresponding facilities of the host operating system via virtualization components of the virtual computer so that the simulated storage operating system operates substantially the same as the actual storage operating system on low cost host hardware platforms.
