    摘要: Described are a system and method of migrating data stored logical units of storage (LUNs) at a source storage array to a plurality of destination storage arrays transparently with respect to a host in communication with the source storage array through a switch. The source storage array is divided into a plurality of source virtual arrays including a first source virtual array and a second source virtual array. Each destination storage array is divided into one or more destination virtual arrays. During a data migration event, data stored in a LUN of the first source virtual array are copied to a corresponding LUN of a destination virtual array of a first one of the destination storage arrays, and data stored in a LUN of the second source virtual array are copied to a corresponding LUN of a destination virtual array of a second one of the destination storage arrays.

    摘要: Failover is provided between groups of logical units of storage presented as virtual arrays. A primary virtual array has at least one primary virtual port coupled to a fabric, each primary virtual port having a source virtual port name and a source virtual port address. A secondary virtual array has one or more secondary virtual ports coupled to the fabric, each secondary virtual port having a secondary virtual port name and a secondary virtual port address. All data resident on the primary virtual array is copied to the secondary virtual array. If a failure occurs in the primary virtual array, the secondary virtual port names and LUN names and numbers are replaced with the primary virtual port names and LUN names and numbers. The fabric then updates its name server database so that the database associates the primary virtual port names and LUN names and numbers with the secondary virtual port addresses.

    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: Described are systems and methods of migrating data from a source array to a destination array transparently with respect to a management application program executing on a host system and using management information to send management messages to the storage arrays. Data are copied from the source array to the destination array during a data migration event. A first array management interface is associated with the source array and a second array management interface is associated with the destination array. Each array management interface includes management information that a management application executing on the host can use to communicate with the storage array. The first and second array management interfaces are exchanged during the data migration event so that the array management interface associated with the destination array becomes associated with the source array and the array management interface associated with the source array becomes associated with the destination array.

    摘要: Source and destination fiber channel devices are coupled to a fiber channel fabric. Hosts communicate with the fiber channel devices using fiber channel addresses. All data is copied from the source fiber channel device to the destination fiber channel device. Source port names and LUN names are exchanged with destination port names and LUN names so that the source device has the destination port and LUN names and the destination device has the source port and LUN names. The fabric reloads its name server database for use by the host(s) so that the database associates the source port and LUN names with the destination port and LUN names and the destination port and LUN names with the source port and LUN names. The names known to the host have not changed and the destination fiber channel device now appears to the host as the source fiber channel device.

    摘要: Described are systems and methods of migrating data and metadata from a source storage array to a destination storage array transparently with respect to a storage application executing on a host. The storage application provides particular storage functionality at the source storage array while using metadata during its execution. During a data migration event in which data resident in disks at the source storage array are fully copied to the destination storage array, metadata stored at the source storage array are copied to the destination storage array. After the data migration event, the destination storage array assumes the personality of the source storage array.
