System and method for managing storage networks and providing virtualization of resources in such a network using one or more ASICs

1. A system for managing a plurality of storage area networks including a plurality of data storage volumes and one or more hosts, the system comprising:

a virtualization application-specific integrated circuit (ASIC) having a storage and switch controller and at least one microprocessor embedded on it; and a disk for storing meta-data related to the plurality of data storage volumes such that the one or more data storage networks are managed by the virtualization ASIC using the meta-data and by controlling one or more switches between the one or more data storage networks; wherein the virtualization ASIC supports virtual Storage Area Networks (SAN)s by parsing between front-end SANs and back-end SANs regardless of physical configuration of the SANs, to enable mapping from virtual volumes to back-end storage elements across virtual SANs.

2. The system of claim 1 , wherein the ASIC running as a storage and switch controller forms a storage area network management entity that is separate from a host or the plurality of data storage volumes.

3. The system of claim 2 , wherein a switch abstraction layer agent embedded on the controller is provided for managing switches in the data storage network.

4. The system of claim 1 , wherein the plurality of storage area networks are represented by a plurality of virtual storage area networks.

5. The system of claim 4 , wherein the plurality of virtual storage area networks includes a plurality of virtual storage volumes.

6. The system of claim 1 , wherein a switch abstraction layer is embedded on the ASIC for managing switches in the storage network.

7. The system of claim 6 , wherein the plurality of storage area networks are represented by a plurality of virtual storage area networks.

8. The system of claim 7 , wherein the plurality of virtual storage area networks includes a plurality of virtual storage volumes.

9. A method for managing a plurality of storage area networks including a plurality of data storage volumes and one or more hosts, the method comprising the steps of:

using a virtualization application-specific integrated circuit (ASIC) having a storage and switch controller and at least one microprocessor embedded on it to manage one or more data storage networks using meta-data related to the plurality of data storage volumes; wherein the virtualization ASIC supports virtual Storage Area Networks (SAN)s by parsing between front-end SANs and back-end SANs regardless of physical configuration of the SANs, to enable mapping from virtual volumes to back-end storage elements across virtual SANs and

using the ASIC to manage switches between the one or more data storage networks.

10. The method of claim 9 , wherein the ASIC running as a storage and switch controller forms a storage area network management entity that is separate from a host or the plurality of data storage volumes.

11. The method of claim 10 , wherein a switch abstraction layer agent embedded on the controller is provided for managing switches in the data storage network.

12. The method of claim 9 , wherein the plurality of storage area networks are represented by a plurality of virtual storage area networks.

13. The method of claim 12 , wherein the plurality of virtual storage area networks includes a plurality of virtual storage volumes.

14. The method of claim 9 , wherein a switch abstraction layer is embedded on the ASIC for managing switches in the storage network.

15. The method of claim 14 , wherein the plurality of storage area networks are represented by a plurality of virtual storage area networks.

16. The method of claim 15 , wherein the plurality of virtual storage area networks includes a plurality of virtual storage volumes.
