ABSTRACT:
A virtual user interface allows a collection or cluster of data storage devices (nodes of the cluster) to be managed remotely by providing access to cluster management software running on one or more nodes of the cluster. Moreover, the virtual user interface fails-over, such that, if a node hosting an instance of the virtual user interface is unable to continue hosting (e.g., communication becomes unreliable, hardware failure, etc.), the hosting duties are substantially automatically migrated to another node in the cluster. Further, failover rules are substantially automatically organized at an initiation of the cluster, and adjusted in accordance with ongoing events occurring in the cluster to provide an administrator with substantially seamless cluster management capabilities.
