Abstract
The present invention is directed to data migration, and particularly, Parity Group migration, between high performance data generating entities and data storage structure in which distributed NVM arrays are used as a single intermediate logical storage which requires a global registry/addressing capability that facilitates the storage and retrieval of the locality information (metadata) for any given fragment of unstructured data and where Parity Group Identifier and Parity Group Information (PGI) descriptors for the Parity Groups' members tracking, are created and distributed in the intermediate distributed NVM arrays as a part of the non-deterministic data addressing system to ensure coherency and fault tolerance for the data and the metadata. The PGI descriptors act as collection points for state describing the residency and replay status of members of the Parity Groups.
