Abstract
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.
