Abstract

An apparatus and method for configuring available storage capacity that is available on a network as a logical device for common use thereof. The invention is preferably embodied in computer readable program code. The available storage capacity may be identified by monitoring storage resources on the network (e.g., NAS, SAN, PC attached storage, server attached storage, etc.) and determining the available storage capacity thereof. The available storage capacity is allocated for common use as a logical device, and managed according to a management policy. For example, the logical device may be managed by translating between access protocols, routing data to the portion of the logical device best suited to store the data, etc.

Claims

1. ) A method of configuring available storage capacity on a network, comprising:

a) identifying said available storage capacity of at least two types of storage resources on said network;

b) allocating said indentified storage capacity as a logical device; and

c) managing access to said logical device.

2. ) A method, as in claim 1, wherein identifying said available storage capacity comprises:

a) monitoring said storage resources on said network; and

b) determining said available storage capacity thereon.

3. ) A method, as in claim 1, wherein allocating said available storage capacity comprises identifying a path for access thereto.

4. ) A method, as in claim 1, wherein allocating said available storage capacity comprises identifying access protocols for said available storage capacity.

5. ) A method, as in claim 4, wherein managing access comprises translating said access protocols when a request for access to said logical device so requires.

6. ) A method, as in claim 1, wherein allocating said available storage capacity comprises classifying said available storage capacity.

7. ) A method, as in claim 6, wherein managing access comprises routing data to a portion of said logical device best suited for handling said data based on said classification of said available storage capacity.

8. ) A method, as in claim 1, wherein said allocated storage capacity is accessible only via said logical device.

9. ) A method, as in claim 1, further comprising transparently reallocating at least a portion of said logical device for direct access thereto when needed by said storage resource from which said available storage capacity was originally allocated.

10. ) An apparatus for configuring available storage capacity on a network, comprising:

computer readable storage media;

computer readable program code stored on said computer readable storage media, comprising;

a) program code for identifying said available storage capacity of at least two types of storage resources on said network;

b) program code for allocating said available storage capacity as a logical device; and

c) program code for managing said logical device.

11. ) An apparatus, as in claim 10, further comprising program code for monitoring said storage resources on said network to determine said available storage capacity thereon that is available for allocating.

12. ) An apparatus, as in claim 10, further comprising program code for generating a management policy for managing said logical device.

13. ) An apparatus, as in claim 12, wherein said management policy includes at least a path and an access protocol each corresponding to said allocated storage capacity.

14. ) An apparatus, as in claim 12, wherein said management policy includes characteristics of, and restrictions for access to, said allocated storage capacity.

15. ) An apparatus, as in claim 10, further comprising program code for blocking direct access to said allocated storage capacity.

16. ) An apparatus, as in claim 10, further comprising program code for reallocating at least a portion of said allocated storage capacity from said logical device for direct access thereto by said storage resource from which said available storage capacity was originally allocated.

17. ) An apparatus, as in claim 10, further comprising program code for routing data to a portion of said logical device best suited for handling said data.

18. ) An apparatus, as in claim 10, further comprising program code for translating at least one access protocol of said allocated storage capacity to provide access to said logical device.

20. ) An apparatus, as in claim 19, further including means for routing data to a portion of said allocated storage best suited for handling said data.

19. ) An apparatus for configuring available storage capacity on a network for common use thereof, comprising:

means for identifying said available storage capacity on said network;

means for allocating said available storage capacity; and

means for managing said allocated storage capacity.
