Abstract

Techniques and mechanisms described herein facilitate the transmission of a data stream to a networked storage system. According to various embodiments, a request to transfer the data stream to the networked storage system may be received at a data mover located at a client device. The data mover may be configured to transfer data to the networked storage system via two different communications protocol interfaces. The data stream may be transmitted to the networked storage system over a network via a first one of the interfaces when a first characteristic associated with the data stream meets a designated criterion.

Claims

1. A method comprising:

receiving a request to transfer a data stream to a networked storage system, the request received at a data mover located at a client device comprising a processor and memory, the data mover configured to transfer data to the networked storage system via a first communications protocol interface and a second communications protocol interface; and

transmitting the data stream to the networked storage system over a network via the first communications protocol interface when a first characteristic associated with the data stream meets a designated communications protocol criterion.

2. The method recited in claim 1, wherein the designated communications protocol criterion identifies a file size threshold, and wherein the data stream is transmitted to the networked storage system via the first communications protocol interface when a file associated with the data stream has a file size that exceeds the file size threshold.

3. The method recited in claim 1, wherein the designated communications protocol criterion identifies an encryption status, and wherein the data stream is transmitted to the networked storage system via the first communications protocol interface when it is determined that the data stream is encrypted.

4. The method recited in claim 1, wherein the designated communications protocol criterion identifies a data sequentialness threshold, and wherein the data stream is transmitted to the networked storage system via the first communications protocol interface when it is determined that the data stream meets the data sequentialness threshold.

5. The method recited in claim 1, wherein transmitting the data stream to the networked storage system via the first communications protocol interface comprises deduplicating the data stream at the client device.

6. The method recited in claim 5, wherein deduplicating the data stream comprises:

parsing the data stream to produce a plurality of data chunks,

and fingerprinting each of the data chunks to produce a plurality of chunk fingerprints.

7. The method recited in claim 6, wherein deduplicating the data stream further comprises:

for each fingerprint, determining whether a chunk corresponding with the fingerprint is stored on the networked storage system, and

when it is determined that the chunk is not stored at the networked storage system, transmitting the chunk to the networked storage system for storage.

8. The method recited in claim 5, wherein the second communications protocol interface is not operable to deduplicate the data stream at the client device.

9. The method recited in claim 1, wherein the request to transfer the data stream conforms to the Open Storage (OST) protocol.

10. The method recited in claim 1, wherein the request to transfer the data stream conforms to a communications protocol selected from the group consisting of:

the Network File System (NFS) protocol, and the Common Internet File System (CIFS) protocol.

11. The method recited in claim 1, wherein the networked storage system is operable to store deduplicated data based on storage requests received via the network.

12. A device comprising:

memory configured to store a request to transfer a data stream to a networked storage system, the request received at a data mover located at a client device comprising a processor and memory, the data mover configured to transfer data to the networked storage system via a first communications protocol interface and a second communications protocol interface; and

a processor configured to issue an instruction to transmit the data stream to the networked storage system over a network via the first communications protocol interface when a first characteristic associated with the data stream meets a designated communications protocol criterion.

13. The device recited in claim 12, wherein the designated communications protocol criterion identifies a file size threshold, and wherein the data stream is transmitted to the networked storage system via the first communications protocol interface when a file associated with the data stream has a file size that exceeds the file size threshold.

14. The device recited in claim 12, wherein the designated communications protocol criterion identifies an encryption status, and wherein the data stream is transmitted to the networked storage system via the first communications protocol interface when it is determined that the data stream is encrypted.

15. The device recited in claim 12, wherein the designated communications protocol criterion identifies a data sequentialness threshold, and wherein the data stream is transmitted to the networked storage system via the first communications protocol interface when it is determined that the data stream meets the data sequentialness threshold.

16. The device recited in claim 12, wherein transmitting the data stream to the networked storage system via the first communications protocol interface comprises deduplicating the data stream at the client device.

17. The device recited in claim 16, wherein deduplicating the data stream comprises:

parsing the data stream to produce a plurality of data chunks,

and fingerprinting each of the data chunks to produce a plurality of chunk fingerprints.

18. The device recited in claim 17, wherein deduplicating the data stream further comprises:

for each fingerprint, determining whether a chunk corresponding with the fingerprint is stored on the networked storage system, and

when it is determined that the chunk is not stored at the networked storage system, transmitting the chunk to the networked storage system for storage.

19. The device recited in claim 16, wherein the second communications protocol interface is not operable to deduplicate the data stream at the device.

20. One or more non-transitory computer readable media having instructions stored thereon for performing a method, the method:

receiving a request to transfer a data stream to a networked storage system, the request received at a data mover located at a client device comprising a processor and memory, the data mover configured to transfer data to the networked storage system via a first communications protocol interface and a second communications protocol interface; and

transmitting the data stream to the networked storage system over a network via the first communications protocol interface when a first characteristic associated with the data stream meets a designated communications protocol criterion.
