Abstract

A method, computer program product, and computing system for receiving a shred command from a host on a storage device associated with a main storage copy within a redundant storage system. The shred command with respect to the main storage copy is processed on the storage device associated with the main storage copy.

Claims (30)

1. A computer-implemented method, executed on a computing system, comprising:

receiving a shred command from a host on a first storage subsystem associated with a main storage copy within a redundant storage system, wherein the first storage subsystem includes a first storage processor and a first set of storage targets, wherein the main storage copy is stored on at least one storage target of the first set of storage targets;

determining a media type for the at least one storage target storing the main storage copy;

processing, via the first storage processor of the first storage subsystem, the shred command with respect to the main storage copy on the at least one storage target storing the main storage copy based, at least in part, upon a shredding procedure specific to the media type for the at least one target storing the main storage copy;

forwarding the shred command to at least a second storage subsystem associated with at least one protection copy within the redundant storage system, wherein each storage subsystem of the at least a second storage subsystem includes a storage processor and a set of storage targets; and

processing, via the storage processor of the at least a second storage subsystem, the shred command with respect to the at least one protection copy on at least one storage target of the at least a second storage subsystem storing the at least one protection copy.

2. The computer-implemented method of claim 1 further comprising:

determining a media type for the at least one storage target of the at least a second storage subsystem storing the at least one protection copy.

3. The computer-implemented method of claim 2 wherein processing the shred command with respect to the at least one protection copy includes:

processing, via the storage processor of the at least a second storage subsystem, the shred command with respect to the at least one protection copy on at least one storage target of the at least a second storage subsystem storing the at least one protection copy based, at least in part, upon the media type for the at least one storage target of the at least a second storage subsystem storing the at least one protection copy.

4. A computer program product residing on a non-transitory computer readable medium having a plurality of instructions stored thereon which, when executed by a processor, cause the processor to perform operations comprising:

receiving a shred command from a host on a first storage subsystem associated with a main storage copy within a redundant storage system, wherein the first storage subsystem includes a first storage processor and a first set of storage targets, wherein the main storage copy is stored on at least one storage target of the first set of storage targets;

determining a media type for the at least one storage target storing the main storage copy;

processing, via the first storage processor of the first storage subsystem, the shred command with respect to the main storage copy on the at least one storage target storing the main storage copy based, at least in part, upon a shredding procedure specific to the media type for the at least one target storing the main storage copy;

forwarding the shred command to at least a second storage subsystem associated with at least one protection copy within the redundant storage system, wherein each storage subsystem of the at least a second storage subsystem includes a storage processor and a set of storage targets; and

processing, via the storage processor of the at least a second storage subsystem, the shred command with respect to the at least one protection copy on at least one storage target of the at least a second storage subsystem storing the at least one protection copy.

5. The computer program product of claim 4 further comprising:

determining a media type for the at least one storage target of the at least a second storage subsystem storing the at least one protection copy.

6. The computer program product of claim 5 wherein processing the shred command with respect to the at least one protection copy includes:

processing, via the storage processor of the at least a second storage subsystem, the shred command with respect to the at least one protection copy on at least one storage target of the at least a second storage subsystem storing the at least one protection copy based, at least in part, upon the media type for the at least one storage target of the at least a second storage subsystem storing the at least one protection copy.

7. A computing system including a processor and memory configured to perform operations comprising:

receiving a shred command from a host on a first storage subsystem associated with a main storage copy within a redundant storage system, wherein the first storage subsystem includes a first storage processor and a first set of storage targets, wherein the main storage copy is stored on at least one storage target of the first set of storage targets;

determining a media type for the at least one storage target storing the main storage copy;

processing, via the first storage processor of the first storage subsystem, the shred command with respect to the main storage copy on the at least one storage target storing the main storage copy based, at least in part, upon a shredding procedure specific to the media type for the at least one target storing the main storage copy;

forwarding the shred command to at least a second storage subsystem associated with at least one protection copy within the redundant storage system, wherein each storage subsystem of the at least a second storage subsystem includes a storage processor and a set of storage targets; and

processing, via the storage processor of the at least a second storage subsystem, the shred command with respect to the at least one protection copy on at least one storage target of the at least a second storage subsystem storing the at least one protection copy.

8. The computing system of claim 7 further configured to perform operations comprising:

determining a media type for the at least one storage target of the at least a second storage subsystem storing the at least one protection copy.

9. The computing system of claim 8 wherein processing the shred command with respect to the at least one protection copy includes:

processing, via the storage processor of the at least a second storage subsystem, the shred command with respect to the at least one protection copy on at least one storage target of the at least a second storage subsystem storing the at least one protection copy based, at least in part, upon the media type for the at least one storage target of the at least a second storage subsystem storing the at least one protection copy.
