摘要
An apparatus comprising a first of a plurality of array modules and a second of a plurality of array modules. The first of the plurality of array modules may be configured to connect a first one or more of a plurality of host devices to a first one or more of a plurality of storage arrays. The first array module may comprise a primary controller and a secondary controller. The second of the plurality of array modules may be configured to connect a second one or more of the plurality of host devices to a second one or more of the plurality of storage arrays. The second array module may comprise a primary controller and a secondary controller. Control of access to the storage arrays may be transferred to the secondary controller of the first array module during a failure of the primary controller of the first array module.
