Mobility and management layer for multi-platform enterprise data storage

A multi-platform data storage system for accessing a plurality of storage platforms that use different storage access or storage management protocols, the multi-platform data storage system comprising:

• a storage mobility and management layer providing virtual management of data stored in the plurality of storage platforms;
• and
• a storage protocol converter operatively coupled between the storage mobility and management layer and the plurality of storage platforms, wherein during access or management communication from the storage mobility and management layer to a particular one of the storage platforms, the storage protocol converter operates to convert the access and/or management communication from a layer protocol used by the storage mobility and management layer to the storage access protocol used by the particular one of the storage platforms,
• wherein the storage mobility and management layer comprises a composition service that forms a virtual storage resource (VSR) from a plurality of virtual data blocks (VDB), and maintains a mapping of the virtual data blocks to the virtual storage resource, and wherein mapping data pertaining to the mapping is stored in a virtual data block.
