Abstract

A method and apparatus for interfacing a client using a first communication protocol with a distributed file system using a second communication protocol is described. The apparatus has a client interface and a file system driver. The client interface communicates with the client using the first communication protocol. The file system driver is coupled to the client interface and receives a communication from the client using the first communication protocol. The file system driver communicates with the distributed file system using the second communication protocol. Files in the distributed file system are divided and stored amongst distinct physical storage locations.

Claims

1. A method for interfacing a client having a first communication protocol with a distributed file system having a second communication protocol, the method comprising:

receiving a communication directed to a file stored on the distributed file system from the client with the first communication protocol; and

communicating with the distributed file system using the second communication protocol on behalf of the client, wherein the file is divided and stored in a plurality of distinct physical storage locations.

2. The method of claim 1 wherein communicating further comprises:

locating the file on the plurality of storage locations; and

reconstructing the file.

3. The method of claim 1 wherein the first communication protocol comprises NFS, FTP, AFP, or Samba/CIFS.

4. The method of claim 1 wherein the second communication protocol is not compatible with the first communication protocol.

5. The method of claim 1 further comprising authenticating the client.

6. An apparatus for interfacing a client having a first communication protocol with a distributed file system having a second communication protocol, the apparatus comprising:

a client interface for receiving a communication from the client with the first communication protocol; and

a file system driver coupled to the client interface, and for communicating with the distributed file system using the second communication protocol on behalf of the client, wherein the file is divided and stored in a plurality of distinct physical storage locations.

7. The apparatus of claim 6 wherein the first communication protocol further comprises NFS, FTP, AFP, or Samba/CIFS.

8. The apparatus of claim 6 wherein the second communication protocol is not compatible with the first communication protocol.

9. The apparatus of claim 6 wherein the distributed file system includes an authentication server associated with the second communication protocol.

10. A system comprising:

a client communicating with a first communication protocol;

a switch coupled to the client;

a gateway server coupled to the switch; and

a distributed file system communicating with a second communication protocol, the distributed file system comprising an Ethernet switch, a content director, and a plurality of content servers, the plurality of content servers storing portions of files,

wherein the gateway server communicates with the distributed file system on behalf of the client using the second communication protocol.

11. The system of claim 10 wherein the distributed file system further comprises a metadata server for authenticating a communication between the client and the distributed file system.

12. The system of claim 10 wherein the first communication protocol comprises NFS, FTP, AFP, or Samba/CIFS.

13. The system of claim 10 wherein the second communication protocol is not compatible with the first communication protocol.

14. The system of claim 10 wherein the gateway server further comprises:

a client interface for receiving a communication from the client with the first communication protocol; and

a file system driver coupled to the client interface, and for communicating with the distributed file system using the second communication protocol on behalf of the client.

16. The method of claim 14 wherein the first communication protocol comprises NFS, FTP, AFP, or Samba/CIFS.

17. The method of claim 14 wherein the second communication protocol is not compatible with the first communication protocol.

18. The method of claim 14 further comprising authenticating the client.

15. A program storage device readable by a machine, tangibly embodying a program of instructions executable by the machine to perform a method for interfacing a client using a first communication protocol with a distributed file system using a second communication protocol, the method comprising:

receiving a communication directed to a file stored on the distributed file system from the client with the first communication protocol; and

communicating with the distributed file system using the second communication protocol on behalf of the client, wherein the file is divided and stored in a plurality of distinct physical storage locations.
