Parallel migration of data objects to clustered storage

摘要

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.

1. A method comprising:
determining a plurality of data objects to be migrated via a plurality of migration data paths, wherein each of the plurality of migration data paths indicates a source, a destination, and an intermediate storage and each of the plurality of migration data paths is unique among the plurality of migration data paths; for each of the plurality of migration data paths, associating the migration data path and a corresponding one of the plurality of data objects with a different migration process; each of the migration processes,
configuring a space in the intermediate storage indicated by the associated migration data path to receive data;causing replication of the associated data object from the source indicated by the associated migration data path to the configured intermediate storage space;causing replication of data in the configured intermediate storage space to the destination indicated by the associated migration data path.
