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.

Described are a system and method of migrating data stored in logical units of storage (LUNs) at a plurality of source arrays into one destination storage array transparently with respect to a host communicating with the source storage arrays through a switch. During a data migration event, data stored in a LUN of a first source storage array are copied to a first corresponding LUN of the destination storage array and data stored in a LUN of a second source storage array are copied to a second corresponding LUN of the destination storage array.

Described is a system and method of migrating all data resident in disks at a source storage array to a plurality of destination storage arrays transparently with respect to a host communicating with the source storage array through a switch. During a data migration event, data stored in a first logical units of storage (LUN) of the source storage array is copied to a corresponding LUN of a first destination storage array, and data stored in a second LUN of the source storage array is copied to a corresponding LUN of a second destination storage array.
摘要:
A clustered storage array consists of several nodes coupled to one or more storage systems. The nodes provide a LUN-device for access by a client, the LUN-device mapping to a source logical unit corresponding to areas of storage on the one or more storage systems. A target logical unit corresponds to different areas of storage on the one or more storage systems. The source logical unit is migrated in parallel by the several nodes to the target logical unit.
