摘要： Described is non-disruptive data migration from a source array to a heterogeneous destination array. A name server database is queried to obtain port names for each source array port. The source array is queried to obtain information about each source array LUN. A target array is generated at the destination array for receiving a copy of data resident at the source array. The target array has at least as many ports and at least as many LUNs as the source array. Each source array LUN corresponds to a target array LUN and is equal in storage capacity as that corresponding LUN. All data resident in the source array LUNs are copied to corresponding target array LUNs. The name server database is reconfigured to associate source port names with the port addresses of the target array such that the target array appears to a host as the source array.

摘要： A system, method and computer program product for detecting an additional storage device within an “n” device array. The “n” device array is configured to store “n” device array formatted data. The “n” device array is reconfigured into an “n+m” device array. The “n” device array formatted data is written to the “n+m” device array in an “n+m” device array format. Reconfiguring the “n” device array may include converting the “n” device array formatted data into “n+m” device array formatted data. The “n+m” device array may comprise two storage devices including a mirrored storage device, or may include at least three storage devices including a coded target storage device such as a parity storage device. The coded target storage device may be a distributed coded target as in a RAID array.

摘要： A method and computer program product for receiving a newly-received data portion for storing within a cache memory system. A determination is made concerning whether the newly-received data portion corresponds with at least one data portion previously written to a non-volatile, memory system. If the newly-received data portion does not correspond with at least one previously-written data portion, the newly-received data portion is stored within the cache memory system using a protected data storage methodology.

摘要： Described are a system and method of migrating data stored in logical units of storage (LUNs) at a plurality of source storage arrays into one destination storage array transparently with respect to a host in communication with the source storage arrays through a switch. First and second source storage arrays and a destination storage array are each partitioned into a plurality of source virtual arrays. The destination virtual arrays include a first destination virtual array and a second destination virtual array. Data stored in a LUN of a first source virtual array of the first source storage array are copied to a corresponding LUN of the first destination virtual array of the destination storage array, and data stored in a LUN of a second source virtual array of the second source storage array are copied to a corresponding LUN of the second destination virtual array of the destination storage 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.
