Abstract

In accordance with the present disclosure, a system and method for providing an optimized distributed storage system is described. The method may comprise receiving a file at a processor of a first information handling system of the distributed storage system. A copy of the file may be stored in a second information handling system of the distributed storage system. A total accessibility value for the file may be determined. The method may further include storing a copy of the file in a third information handling system of the distributed storage system if the total accessibility value is less than a first threshold. Likewise, a copy of the file may be removed from the second information handling system if the total accessibility value is greater than or equal to a second threshold.

Claims

1. A method for providing an optimized distributed storage system, comprising:

receiving a file at a processor of a first information handling system of the distributed storage system;

storing a copy of the file in a second information handling system of the distributed storage system;

determining a total accessibility value for the file; and

storing a copy of the file in a third information handling system of the distributed storage system if the total accessibility value is less than a first threshold.

2. The method of claim 1, further comprising determining a separate accessibility value for each information handling system of the distributed storage system.

3. The method of claim 2, wherein determining at the processor the total accessibility value for the file comprises adding the separate accessibility value of each information handling system of the distributed storage system in which a copy of the file is stored.

4. The method of claim 2, wherein the separate accessibility value is determined, based at least in part, on an accessibility parameter of the corresponding information handling system.

5. The method of claim 4, wherein the accessibility parameter indicates at least one of:

the duration with which the corresponding information handling system is coupled to a network, and

a location of the corresponding information handling system relative to the first information handling system.

6. The method of claim 1, further comprising removing the copy of the file from the second information handling system if the total accessibility value is greater than or equal to a second threshold.

7. The method of claim 6, wherein the first threshold comprises a pre-determined minimum accessibility value for the distributed storage system.

8. The method of claim 7, wherein the second threshold comprises a pre-determined maximum accessibility value for the distributed storage system.

9. A non-transitory, tangible storage medium containing a set of instructions, wherein the set of instructions, when executed by a processor within a first information handling system of a distributed storage system, is operable to cause the processor to:

receive a file selected by a user;

store a copy of the file in a second information handling system of the distributed storage system;

determine a total accessibility value for the file; and

store a copy of the file in a third information handling system of the distributed storage system if the total accessibility value is lower than a first threshold.

10. The non-transitory, tangible storage medium of claim 9, wherein the set of instructions is further operable to cause the processor to determine a separate accessibility value for each information handling system of the distributed storage system.

11. The non-transitory, tangible storage medium of claim 10, wherein the set of instructions is further operable to cause the processor to determine the total accessibility value for the file by adding the separate accessibility values of each information handling system of the distributed storage system in which the copy of the file is stored.

12. The non-transitory, tangible storage medium of claim 10, wherein the separate accessibility value is based, at least in part, on an accessibility parameter of the corresponding information handling system.

13. The non-transitory, tangible storage medium of claim 12, wherein the accessibility parameter indicates at least one of:

the duration with which the corresponding information handling system is coupled to a network, and

a location of the corresponding information handling system relative to the first information handling system.

14. The non-transitory, tangible storage medium of claim 9, wherein the set of instructions is further operable to cause the processor to remove the copy of the file from the second information handling system if the total accessibility value is greater than or equal to a second threshold.

15. The non-transitory, tangible storage medium of claim 14, wherein the first threshold comprises a pre-determined minimum accessibility value for the distributed storage system.

16. The non-transitory, tangible storage medium of claim 15, wherein the second threshold comprises a pre-determined maximum accessibility value for the distributed storage system.

17. An information handling system, comprising:

a processor;

a network interface coupled to the processor, wherein the information handling system is operable to communicate within a distributed storage system through the network interface; and

a memory device coupled to the processor, wherein the memory device contains a set of instructions operable to cause the processor to;

receive a file selected by a user;

store a copy of the file in a first information handling system of the distributed storage system;

determine a total accessibility value for the file;

store a copy of the file in a second information handling system of the distributed storage system if the total accessibility value is lower than a first threshold; and

remove the copy of the file from the first information handling system if the total accessibility value is greater than or equal to a second threshold.

18. The information handling system of claim 17, wherein the first information handling system is a required storage location.

19. The information handling system of claim 18, wherein the first threshold comprises a pre-determined minimum accessibility value for the distributed storage system, and the second threshold comprises a pre-determined maximum accessibility value for the distributed storage system.

20. The information handling system of claim 17, wherein the set of instructions is further operable to cause the processor to:

determine a separate accessibility value for each information handling system of the distributed storage system; and

determine the total accessibility value for the file by adding the separate accessibility values of each information handling system of the distributed storage system in which the copy of the file is stored.
