Abstract

A data packet is generated. An instruction relating to a selected data processing operation, and information indicating that additional processing of the data packet is required, are inserted into the data packet. For example, the information may comprise a predetermined bit or a predetermined sequence of bits. In one embodiment, the information is inserted at a predetermined location within the data packet. The data packet is inserted into a selected field of an iSCSI command. For example, the data packet may be inserted into a buffer field of the iSCSI command. The iSCSI command is transmitted.

Claims

1. A method of managing data, the method comprising:

inserting into a data packet an instruction relating to a selected data processing operation and information indicating that additional processing of the data packet is required;

inserting the data packet into a selected field of an iSCSI command; and

transmitting the iSCSI command.

2. The method of claim 1, further comprising:

inserting the information at a predetermined location within the data packet.

3. The method of claim 1, further comprising:

inserting the data packet into a buffer field of the iSCSI command.

4. The method of claim 1, further comprising:

compressing selected data, generating compressed data; and

inserting the compressed data into the data packet.

5. The method of claim 1, further comprising:

encrypting the data packet.

6. The method of claim 1, wherein the instruction relates to one of:

a compression operation, a decompression operation, a deduplication operation, a backup operation, a synchronization operation, a write operation, a copy operation, and a snapshot operation.

7. The method of claim 6, wherein the instruction relates to a write operation,

the method further comprising:

inserting into a selected field of the data packet second information indicating a start sector to which data is to be written.

8. The method of claim 6, wherein the instruction relates to a deduplication operation,

the method further comprising:

inserting into a first selected field of the data packet second information indicating a source sector from which data is to be deduplicated; and

inserting into a second selected field of the data packet third information indicating a start sector to which data is to be deduplicated.

9. The method of claim 1, wherein the information comprises one of:

a predetermined bit and a predetermined sequence of bits.

10. A method of managing data, the method comprising:

receiving an iSCSI command comprising a data packet;

detecting, in the data packet, first information indicating that additional processing of the data packet is required and second information relating to a specified data processing operation; and

performing the specified data processing operation, based on the second information.

11. The method of claim 10, wherein the data packet is within a buffer field of the iSCSI command.

12. The method of claim 10, wherein the first information is located at a predetermined location within the data packet.

13. The method of claim 10, wherein the first information comprises one of:

a predetermined bit and a predetermined sequence of bits.

14. The method of claim 10, wherein the data packet is encrypted,

the method further comprising:

decrypting the encrypted data packet.

15. The method of claim 10, wherein the specified data processing operation comprises one of a compression operation, a decompression operation, a deduplication operation, a backup operation, a synchronization operation, a write operation, a copy operation, and a snapshot operation.

16. The method of claim 15, wherein the second information comprises a first instruction relating to a decompression operation and a second instruction relating to a deduplication operation,

the method further comprising:

performing a decompression operation based on the first instruction; and

performing a deduplication operation based on the second instruction.

17. The method of claim 10, further comprising:

retrieving data from the data packet; and

performing the specified data processing operation with respect to the data, based on the second information.

18. An apparatus comprising:

a memory storing computer program instructions; and

a processor configured to execute the computer program instructions which, when executed on the processor, cause the processor to perform operations comprising;

inserting into a data packet an instruction relating to a selected data processing operation and information indicating that additional processing of the data packet is required;

inserting the data packet into a selected field of an iSCSI command; and

transmitting the iSCSI command.

19. The apparatus of claim 18, the operations further comprising:

inserting the information at a predetermined location within the data packet.

20. The apparatus of claim 18, the operations further comprising:

inserting the data packet into a buffer field of the iSCSI command.

21. The apparatus of claim 18, the operations further comprising:

compressing selected data, generating compressed data; and

inserting the compressed data into the data packet.

22. The apparatus of claim 18, the operations further comprising:

encrypting the data packet.

23. The apparatus of claim 18, wherein the instruction relates to one of:

a compression operation, a decompression operation, a deduplication operation, a backup operation, a synchronization operation, a write operation, a copy operation, and a snapshot operation.

24. The apparatus of claim 23, wherein the instruction relates to a write operation,

the operations further comprising:

inserting into a selected field of the data packet second information indicating a start sector to which data is to be written.

25. The apparatus of claim 23, wherein the instruction relates to a deduplication operation,

the operations further comprising:

inserting into a first selected field of the data packet second information indicating a source sector from which data is to be deduplicated; and

inserting into a second selected field of the data packet third information indicating a start sector to which data is to be deduplicated.

26. The apparatus of claim 18, wherein the information comprises one of:

a predetermined bit and a predetermined sequence of bits.

27. An apparatus comprising:

a memory storing computer program instructions; and

a processor configured to execute the computer program instructions which, when executed on the processor, cause the processor to perform operations comprising;

receiving an iSCSI command comprising a data packet;

detecting, in the data packet, first information indicating that additional processing of the data packet is required and second information relating to a specified data processing operation; and

performing the specified data processing operation, based on the second information.

28. The apparatus of claim 27, wherein the data packet is within a buffer field of the iSCSI command.

29. The apparatus of claim 27, wherein the first information is located at a predetermined location within the data packet.
