An embodiment may utilize zoning capabilities to assign a subset of physical storage devices with each storage controller. One or more storage controllers may detect that a storage controller/server has failed and may reconfigure zoning of the physical storage devices originally zoned in with the failed storage controller such that the physical storage devices of the failed zone are zoned out of the failed zone and zoned in with at least one of the remaining functional storage controllers. A reverse process may be used on recovery. An embodiment may further represent each of the physical devices zoned in with a storage controller as at least one virtual storage device and configure an additional comprehensive zone incorporating the storage controllers such that each storage controller has access to all physical storage devices through the virtual storage devices."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"High availability raid using low-cost direct attached raid controllers","description":"A method and storage controller for providing active-active RAID functionality within storage controller device(s).
