US 2015/0178014 A1 · PARALLEL MIGRATION OF DATA OBJECTS TO CLUSTERED STORAGE

Abstract

Data objects can be migrated, while live, to virtualized clustered storage arrays in an efficient manner to allow for efficient transition from non-clustered storage to the virtualized clustered storage arrays. A data migration specification indicates data objects to be migrated and parameters for the migration. The parameters include a source of a data object, a destination of the data object in the virtualized clustered storage arrays, and a transfer space. A migration engine validates and parses the data migration specification. For each unique association of source, destination, and transfer space, the migration engine instantiates a migration process that drives and monitors migration of the corresponding data object. The migration processes operate in parallel for migration of the specified data objects into the virtualized clustered storage arrays.
