Abstract

In one general embodiment, a computer-implemented method is provided. The computer-implemented method includes identifying a first object in a tiered storage system, and identifying first metadata associated with the first object. The computer-implemented method also includes identifying a second object utilizing the first metadata of the first object. The second object is associated with second metadata. Moreover, the computer-implemented method includes, in response to an access of the first object, modifying a heat value associated with the second object.

Claims

1. A computer-implemented method, comprising:

identifying a first object in a tiered storage system;

identifying first metadata associated with the first object, the first metadata including a plurality of details of a creation of the first object;

identifying second metadata associated with a second object, the second metadata including a plurality of details of a creation of the second object;

determining a relationship between the first object and the second object when the second metadata meets predetermined criteria when compared to the first metadata; and

modifying a value associated with the second object in response to an access of the first object, based on the relationship between the first object and the second object.

2. The computer-implemented method of claim 1, wherein the plurality of details of the creation of the first object include an identification of a user that created the first object, a time of the creation of the first object, a date of the creation of the first object, and a geographic location of the creation of the first object.

3. The computer-implemented method of claim 1, comprising, based on the access of the first object, moving the first object from a first tier of storage to a second tier of storage.

4. The computer-implemented method of claim 3, comprising comparing the value associated with the second object to a threshold, and moving the second object from a third tier of storage to a fourth tier of storage when the value exceeds the threshold.

5. The computer-implemented method of claim 4, wherein the first tier of storage comprises the third tier of storage, and the second tier of storage comprises the fourth tier of storage, such that the first object and the second object are moved between the same tiers of storage based on the access of the first object.

6. The computer-implemented method of claim 4, wherein the first tier of storage is different than the third tier of storage.

7. The computer-implemented method of claim 1, wherein the second object is identified utilizing the first metadata of the first object and the second metadata of the second object.

21. The computer-implemented method of claim 1, further comprising determining a degree of the relationship, where the value associated with the second object is modified in proportion to the degree of the relationship in response to the access of the first object.

22. The computer-implemented method of claim 1, wherein the relationship has an associated degree that is determined based on a number of shared values between the first and second metadata.

23. The computer-implemented method of claim 1, wherein the first metadata further includes one or more keywords, one or more user defined descriptions of the first object, and an access history of the first object.

24. The computer-implemented method of claim 1, wherein the value associated with the second object includes a heat value that is calculated based on a number of times the second object is accessed.

25. The computer-implemented method of claim 1, further comprising indexing the first object and the second object in a database that tracks the relationship between the first object and the second object.

10. A computer program product for performing predictive object tiering based on object metadata, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a processor to cause the processor to:

identify, by the processor, a first object in a tiered storage system;

identify, by the processor, first metadata associated with the first object, the first metadata including a plurality of details of a creation of the first object;

identify, by the processor, second metadata associated with a second object, the second metadata including a plurality of details of a creation of the second object;

determine, by the processor, a relationship between the first object and the second object when the second metadata meets predetermined criteria when compared to the first metadata; and

modify, by the processor, a value associated with the second object in response to an access of the first object, based on the relationship between the first object and the second object.

11. The computer program product of claim 10, wherein the second object is stored in the tiered storage system.

12. The computer program product of claim 10, comprising, based on the access of the first object, moving the first object from a first tier of storage to a second tier of storage.

13. The computer program product of claim 12, comprising comparing the value associated with the second object to a threshold, and moving the second object from a third tier of storage to a fourth tier of storage when the value exceeds the threshold.

14. The computer program product of claim 13, wherein the first tier of storage comprises the third tier of storage, and the second tier of storage comprises the fourth tier of storage, such that the first object and the second object are moved between the same tiers of storage based on the access of the first object.

15. The computer program product of claim 13, wherein the first tier of storage is different than the third tier of storage.

16. The computer program product of claim 10, wherein the second object is identified utilizing the first metadata of the first object and the second metadata of the second object.

18. (canceled)

19. A system, comprising:

a processor and logic integrated with and/or executable by the processor, the logic being configured to;

identify a first object in a tiered storage system;

identify first metadata associated with the first object, the first metadata including a plurality of details of a creation of the first object;

identify second metadata associated with a second object, the second metadata including a plurality of details of a creation of the second object;

determine a relationship between the first object and the second object when the second metadata meets predetermined criteria when compared to the first metadata; and

modify a value associated with the second object in response to an access of the first object, based on the relationship between the first object and the second object.
