Abstract

In one embodiment, a host application may manage a data set maintained at a storage device using a token. A processor 220 of a host computer executing a host application may obtain a token representing a data set. The processor 220 may read a data set result based on the data set into a memory local to the host application. The data set result may be a data set copy, a data set digest, or a data set transformation.

Claims

1. A machine-implemented method for processing a data set, comprising:

obtaining in a host application a token representing the data set; and

using the token to execute a read of a data set result based on the data set into a memory location addressable by the host application.

2. The method of claim 1, wherein the data set result is at least one of a data set copy, a data set digest and an output token of a data set transformation.

3. The method of claim 1, further comprising:

creating the token in the host application; and

sending the token to the data storage system.

4. The method of claim 1, further comprising:

sending a data manipulation agent to a data storage system; and

directing the data storage system to execute the data manipulation agent to perform a transformation on the data set.

5. The method of claim 1, further comprising:

receiving the token from a token source.

6. The method of claim 1, wherein the token source is at least one of a data storage system and a source host application.

7. The method of claim 1, further comprising:

sending the token to a target host application.

8. The method of claim 1, further comprising:

sending the data set to a data storage system.

9. The method of claim 1, wherein a token is invalidated by a change to the data set.

10. A tangible machine-readable medium having a set of instructions detailing a method stored thereon that when executed by one or more processors cause the one or more processors to perform the method, the method comprising:

obtaining the token representing a data set; and

providing an output token of a data set transformation based on the data set to a memory local to the host application using the token.

11. The tangible machine-readable medium of claim 10, wherein the method further comprises:

creating the token in a data storage device.

12. The tangible machine-readable medium of claim 10, wherein the method further comprises:

executing a data manipulation agent to perform a transformation on the data set.

13. The tangible machine-readable medium of claim 12, wherein the method further comprises:

receiving the data manipulation agent from a host application.

14. The tangible machine-readable medium of claim 10, wherein the method further comprises:

receiving the token from a source host application.

15. The tangible machine-readable medium of claim 10, wherein the method further comprises:

generating a compressed token as the output token representing a compressed version of the data set.

16. The tangible machine-readable medium of claim 10, wherein the method further comprises:

generating a decompressed token as the output token representing a decompressed version of the data set.

17. The tangible machine-readable medium of claim 10, wherein the method further comprises:

obtaining an additional token representing an additional data set;

generating a concatenated token as the output token representing the data set and the additional data set.

18. A computer host executing a host application, comprising:

a communication interface to receive a token representing a data set; and

a processor to use the token to execute a read of a data set digest based on the data set into a memory local to the host application.

19. The computer host of claim 18, wherein the dataset digest is at least one of a logical zero check, a cyclical redundancy check, or a cryptographic hash message.

20. The computer host of claim 18, wherein the communication interface receives the token from at least one of a data storage system and a source host application.
