Abstract

A method and apparatus for managing a community of storage resource devices are provided. Management of each storage resource device within a community may be performed through a connection established between an administrator computer and a proxy storage resource device established over an out-of-band network. The proxy storage resource device may collect information related to other members of the community of storage resource devices, and provide such information to the administrator computer. The administrator computer may also obtain information from, and provide commands to, members of the community of storage resource devices through the proxy storage resource device. Information between members of a community of storage resource devices may exchange information using an in-band network.

Claims

1. A method for managing a number of storage resource devices, comprising:

interconnecting a number of storage resource devices to one another to form a community of said storage resource devices;

exchanging information of a first type between said interconnected storage resource devices, wherein said information of said first type includes identification information related to said interconnected storage devices;

nominating a first storage resource device included in said number of interconnected storage resource devices to serve as a proxy; and

providing from said first storage resource device to a first administrator computer at least some of said first information.

2. The method of claim 1, further comprising:

receiving at said first storage resource device a request for information from said first administrator computer related to a second storage resource device.

3. The method of claim 2, further comprising:

said first storage resource device responding to said request for information by forwarding said request for information to said second storage resource device, receiving said requested information from said second storage resource device, and providing said requested information related to said second storage resource device to said first administrator computer.

4. The method of claim 1, further comprising:

said first storage resource device maintaining a list of said interconnected storage devices comprising said community.

5. The method of claim 1, further comprising maintaining on each of said interconnected storage resource devices a list including each of said other interconnected storage resource devices included in said community.

6. The method of claim 1, further comprising:

maintaining a list on each of said interconnected storage resource devices of a subset of said storage resource devices included in said community, wherein a selection of said subset of storage resource devices is received by said proxy storage resource device from said first administrator computer.

7. The method of claim 1, further comprising:

interconnecting an additional storage resource device to said number of interconnected storage devices;

after said interconnecting an additional storage resource device, exchanging said information of said first type between said interconnected storage resource devices, wherein said information of said first type includes identification information related to said interconnected storage devices.

8. The method of claim 1, wherein said first administrator computer is interconnected to said first storage resource device by a first network, said method further comprising:

receiving data for storage from a second network at any one of said storage resource devices included in said community.

9. The method of claim 8, wherein said first and second storage resource devices are interconnected to one another by said second network and are not interconnected to one another by said first network.

10. The method of claim 8, wherein said first network comprises an Internet Protocol network, and wherein said first administrator computer is interconnected to said first storage resource device using an Internet Protocol address of said first storage resource device.

11. The method of claim 10, further comprising:

interconnecting said first administrator computer to said second storage resource device using an Internet Protocol address of said second storage resource device;

receiving at said second storage resource device a request for information related to any storage resource device included in said community;

said second storage resource device responding to said request for information by providing said requested information to said first administrator computer.

12. The method of claim 10, further comprising:

interconnecting a second administrator computer to said first storage resource device using said Internet Protocol address of said first storage resource device;

receiving at said first storage resource device a request for information related to any storage resource device included in said community;

said first storage resource device responding to said request for information by providing said requested information to said second administrator computer.

13. The method of claim 8, wherein said second network comprises one of a Fibre Channel network, an iSCSI network, an Ethernet Network or an SCSI bus, and wherein said first network is not an iSCSI network.

14. A storage system, comprising:

a number of storage resource devices, each including;

at least one storage device;

at least one controller, wherein said controller maintains a list of all other storage resource devices in a storage resource device community;

a first network, wherein any one of said storage resource devices within said storage resource device community is in communication with at least one of;

     1) any other of said other storage resource devices in said storage resource device community; and

     2) a host over said first network.

15. The system of claim 14, wherein one of said storage resource devices is a proxy storage resource device, and wherein said proxy is in communication with said host over said first network.

16. The system of claim 15, further comprising:

a second network, wherein for each of said storage resource devices said at least one storage device is in communication with at least one controller over said second network.

17. The system of claim 16, wherein said controller of at least one of said storage resource devices further includes:

a management controller interconnected to said first network; and

a storage controller interconnected to said second network.

18. The system of claim 17, wherein said proxy includes a management controller, and wherein said management controller of said proxy storage resource device is interconnected to said second network through said storage controller of said proxy storage resource device.

19. The system of claim 17, wherein said management controller and said storage controller of at least one of said number of storage resource devices are implemented in connection with a shared processor.

20. The system of claim 16, wherein at least one of said storage resource devices comprises a number of storage devices.

21. The system of claim 16, wherein said second network interconnects said proxy storage resource device to at least one other of said number of storage resource devices.

22. A data storage system, comprising:

first network means for interconnecting computer devices;

second network means for interconnecting computer devices;

a plurality of means for data storage interconnected to one another by at least said second network means;

means for administering said means for distributed data storage, wherein said means for administering is interconnected to at least one of said means for distributed data storage by said first network means, wherein information related to any of said plurality of means for distributed data storage is obtained by said means for administering by requesting said information from one of said means for distributed data storage; and

means for sending or receiving data, wherein said means for sending or receiving data is interconnected to said means for distributed data storage by said second network means.

23. The system of claim 22, wherein at least one of said plurality of means for distributed data storage is interconnected to other of said means for distributed data storage through said second network means only.

24. The system of claim 22, wherein each of said plurality of means for distributed data storage includes:

means for storing data;

means for controlling a distribution of data on said means for storing data.

25. The system of claim 24, wherein each of said plurality of means for distributed data storage further includes:

means for managing information related said means for distributed data storage, wherein said means for managing information maintains a list identifying each of said means for distributed data storage interconnected to one another.
