## Abstract

A multi-platform data storage system configured to accessing a plurality of storage platforms that use different storage access and/or storage management protocols. The multi-platform data storage system can, for example, include 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. During access and/or management communication from the storage mobility and management layer to a particular one of the storage platforms, the storage protocol converter can operate 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.

## Claims

### Claim 1

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.

### Claim 2 (depends on 1)

A multi-platform data storage system as recited in claim 1, wherein the composition service manages storage of the virtual data blocks to one or more of the plurality of storage platforms via the storage protocol converter, and wherein the format of the virtual data blocks at the composition service is independent of the format of such data which persistently stored in the one or more of the plurality of storage platforms via the storage protocol converter.

### Claim 3 (depends on 1)

A multi-platform data storage system as recited in claim 1, wherein the composition service is able to store data to and retrieve data from the virtual data blocks independent of whether the corresponding virtual data blocks store actual data or mapping data for the mapping.

### Claim 4 (depends on 1)

A multi-platform data storage system as recited in claim 1, wherein the composition service hashes the virtual data blocks and stores the hashed virtual data blocks as content-addressable virtual data blocks.

### Claim 5 (depends on 4)

A multi-platform data storage system as recited in claim 4, wherein the composition service removes virtual data blocks that are duplicates based on comparing corresponding hash values.

### Claim 6 (depends on 4)

A multi-platform data storage system as recited in claim 4, wherein the composition service manages storage of the virtual data blocks to one or more of the plurality of storage platforms via the storage protocol converter, and wherein the format of the virtual data blocks at the composition service is independent of the format of such data which persistently stored in the one or more of the plurality of storage platforms via the storage protocol converter.

### Claim 7 (depends on 4)

A multi-platform data storage system as recited in claim 4, wherein the composition service is able to store data to and retrieve data from the virtual data blocks independent of whether the corresponding virtual data blocks store actual data or mapping data for the mapping.

### Claim 8 (depends on 1)

A multi-platform data storage system as recited in claim 1, wherein the composition service creates a snapshot of a specified one of the virtual storage resources by creating a new, standalone virtual storage resource that maps to the same existing virtual data blocks as does the specified one of the virtual storage resources.

### Claim 9 (depends on 8)

A multi-platform data storage system as recited in claim 8, wherein the new, standalone virtual storage resource for the snapshot does not refer to the specified one of the virtual storage resources.

### Claim 10 (depends on 8)

A multi-platform data storage system as recited in claim 8, wherein the new, standalone virtual storage resource for the snapshot is formed without copying the virtual data blocks mapped to the specified one of the virtual storage resources.

### Claim 11 (depends on 8)

A multi-platform data storage system as recited in claim 8, wherein the new, standalone virtual storage resource for the snapshot is immutable and portable.

### Claim 12 (depends on 1)

A multi-platform data storage system as recited in claim 1, wherein the composition service creates a clone of a specified one of the virtual storage resources by creating a new, standalone virtual storage resource that maps to the same existing virtual data blocks as the specified one of the virtual storage resources.

A multi-platform data storage system as recited in claim 12, wherein the new, standalone virtual storage resource for the clone is mutable.

### Claim 14 (depends on 1)

### Claim 15 (depends on 14)
