Abstract

A method, system, and computer program product for facilitating deduplication product testing in a computing environment is provided. At least one deduplication test file is generated. The at least one deduplication test file is adapted for, when processed through the deduplication product testing, exhibiting a predefined deduplication factor. A definition file is initialized. The definition file defines at least one file characteristic addressed during the generating the at least one deduplication test file to obtain the predefined deduplication factor. The file characteristic may include a file pattern, a file/pattern ratio, and a pattern across multiple files.

Claims

1. A method for facilitating deduplication product testing in a computing environment by a processor in communication with a memory device, comprising:

generating at least one deduplication test file, wherein the at least one deduplication test file is adapted for, when processed through the deduplication product testing, exhibiting a predefined deduplication factor.

2. The method of claim 1, wherein generating the at least one deduplication test file includes generating the at least one deduplication test file adapted for, when processed through the deduplication product testing, exhibiting a deduplication ratio representative of a ratio of first data before a deduplication operation to second data obtained from the deduplication operation.

3. The method of claim 1, further including initializing a definition file defining at least one file characteristic addressed during the generating the at least one deduplication test file to obtain the predefined deduplication factor.

4. The method of claim 2, wherein the defining the at least one file characteristic includes defining at least one of a file pattern, a file/pattern ratio, and a pattern across multiple files.

5. The method of claim 4, wherein the defining the at least one file characteristic includes defining at least one of a file data redundancy characteristic, rate of data change characteristic, and precompressed data characteristic.

6. The method of claim 1, further including providing the at least one deduplication test file to a testing environment in the computing environment, wherein the at least one deduplication test file is accessed by the testing environment.

7. The method of claim 6, further including incorporating the at least one deduplication test file into a deduplication fileset, wherein the deduplication fileset includes a plurality of additional deduplication test files, each of the plurality of additional deduplication test files exhibiting an additional predefined deduplication factor.

8. The method of claim 7, further including testing the deduplication fileset, including the at least one deduplication test file and the plurality of additional deduplication test files, in the testing environment to generate a plurality of data points corresponding to the deduplication factor and each additional deduplication factor.

9. A utility for facilitating deduplication product testing in a computing environment by a processor in communication with a memory device, comprising:

a deduplication module associated with the processor and memory device in the computing environment, wherein the deduplication module is adapted for;

generating at least one deduplication test file, wherein the at least one deduplication test file is adapted for, when processed through the deduplication product testing, exhibiting a predefined deduplication factor.

10. The utility of claim 9, wherein the predefined deduplication factor includes a deduplication ratio representative of a ratio of first data before a deduplication operation to second data obtained from the deduplication operation.

11. The utility of claim 9, wherein the deduplication module is further adapted for initializing a definition file defining at least one file characteristic addressed during the generating the at least one deduplication test file to obtain the predefined deduplication factor.

12. The utility of claim 11, wherein the deduplication module is further adapted for, pursuant to the defining at least one file characteristic, defining at least one of a file pattern, a file/pattern ratio, and a pattern across multiple files.

13. The utility of claim 9, wherein the deduplication module is further adapted for providing the at least one deduplication test file to a testing environment in the computing environment, wherein the at least one deduplication test file is accessed by the testing environment.

14. The utility of claim 13, wherein the deduplication module is further adapted for incorporating the at least one deduplication test file into a deduplication fileset, wherein the deduplication fileset includes a plurality of additional deduplication test files, each of the plurality of additional deduplication test files exhibiting an additional predefined deduplication factor.

15. The utility of claim 14, further including testing module in communication with the deduplication module, wherein the testing module is adapted for testing the deduplication fileset, including the at least one deduplication test file and the plurality of additional deduplication test files, in the testing environment to generate a plurality of data points corresponding to the deduplication factor and each additional deduplication factor.

16. The utility of claim 9, wherein the processor comprises a storage management processor responsible for management of a data storage environment associated with the computing environment.

20. The computer program product of claim 15, further including:

a second executable portion for providing the at least one deduplication test file to a testing environment in the computing environment, wherein the at least one deduplication test file is accessed by the testing environment,

a third executable portion for incorporating the at least one deduplication test file into a deduplication fileset, wherein the deduplication fileset includes a plurality of additional deduplication test files, each of the plurality of additional deduplication test files exhibiting an additional predefined deduplication factor, and

a fourth executable portion for testing the deduplication fileset, including the at least one deduplication test file and the plurality of additional deduplication test files, in the testing environment to generate a plurality of data points corresponding to the deduplication factor and each additional deduplication factor.

17. A computer program product for facilitating deduplication product testing in a computing environment by a processor in communication with a memory device, the computer program product comprising a computer-readable storage medium having computer-readable program code portions stored therein, the computer-readable program code portions comprising:

a first executable portion for generating at least one deduplication test file, wherein the at least one deduplication test file is adapted for, when processed through the deduplication product testing, exhibiting a predefined deduplication factor.

18. The computer program product of claim 17, wherein the predefined deduplication factor includes a deduplication ratio representative of a ratio of first data before a deduplication operation to second data obtained from the deduplication operation.

19. The computer program product of claim 17, further including a second executable portion for initializing a definition file defining at least one file characteristic addressed during the generating the at least one deduplication test file to obtain the predefined deduplication factor.
