摘要： Described are a storage network and method of migrating data from a source virtual array to a destination virtual array transparently with respect to a storage application executing on a host. The storage application provides particular storage functionality at a source storage array while using metadata during its execution. The metadata used by the storage application are associated with the source virtual array and forwarded, during a data migration event in which data resident in logical units of storage (LUNs) of the source virtual array are copied to LUNs of the destination virtual array, to a destination storage array where the metadata is associated with the destination virtual array.

摘要： Failover is provided from a primary Fiber Channel device to a secondary Fiber Channel device. Source and secondary Fiber Channel devices are coupled to a Fiber Channel fabric having a database that associates Fiber Channel names and Fiber Channel addresses of Fiber Channel ports coupled to it. All data is copied from the primary Fiber Channel device to the secondary Fiber Channel device. In response to a failure, secondary port names and LUN names are replaced with the primary port names and LUN names, and the fabric updates its database so that the database associates the secondary port and LUN addresses with the primary port and LUN names. The secondary Fiber Channel device thereby assumes the primary Fiber Channel device's identity.

摘要： Described are systems and methods of migrating data from a source virtual array to a destination virtual array transparently with respect to a management application program executing on a host and using management information to send management messages to the virtual arrays. Data from the source virtual array are copied to the destination virtual array during a data migration event. First and second virtual array management interfaces are associated with the source and destination virtual arrays, respectively. The first and second virtual array management interfaces are exchanged during the data migration event so that the virtual array management interface associated with the destination virtual array becomes associated with the source virtual array and the virtual array management interface associated with the source virtual array becomes associated with the destination virtual array.

摘要： Described are a storage network and method of presenting a virtual array in the storage network. The storage network includes a first storage array and a second storage array. At least one of the first and second storage arrays has one or more logical units of storage assigned to a virtual array that spans the first and second storage arrays. In addition, at least one of the first and second storage arrays has one or more physical ports coupled to the virtual array. The virtual array is assigned a unique virtual port identifier (ID) for each physical port coupled to the virtual array. A host coupled to a switch can communicate with the virtual array using a virtual port ID assigned to the virtual array.

摘要： A storage array presents virtual arrays to hosts through use of virtual port IDs. The storage array includes groups of logical units of storage. The groups are coupled to a switch through at least one physical port. Each group is assigned a unique virtual port ID for each physical port to which it is coupled. The virtual port IDs are assignable by the switch. The virtual port IDs are used by hosts coupled to the switch to exchange data with the groups to which the virtual port IDs are assigned. Further, a zoning table in the switch can associate each virtual port ID to a host facing port on the switch. In this case each host can communicate only with groups of logical units that are assigned virtual IDs associated with the host facing port to which it is coupled.

摘要： Non-disruptive data migration from a source array to a destination array entails generating a virtual array spanning at least one destination array for receiving a copy of all data at the source array. The virtual array has at least as many virtual ports as physical source ports of the source array and at least as many logical units (LUNs) as the source array. Each source array LUN corresponds to a virtual array LUN and equals the storage capacity of that corresponding LUN. Each virtual port has a virtual port address. All data resident in the LUNs of the source array are copied to corresponding LUNs in the virtual array. A name server database is reconfigured to associate port names of the physical source ports with the virtual port addresses of the virtual ports such that the virtual array appears to a host as the source array.
