Abstract

A method for managing data includes obtaining, by a management module, a workload generation request, wherein the workload generation request specifies a plurality of resource devices, identifying available resource devices in a resource device pool based on the plurality of resource devices, performing a latency analysis on the available resource devices to obtain a plurality of resource device combinations and a total latency cost of each resource device combination, and selecting a resource device combination of the plurality of resource device combinations based on the total latency cost of each resource device combination, wherein the resource device combination comprises a second plurality of resource devices and wherein each of the second plurality of resource devices is one of the plurality of resource devices.

First claim

What is claimed is:

1. A method for managing data, the method comprising:
obtaining, by a management module, a workload generation request, wherein the workload generation request specifies a plurality of resource devices;
identifying available resource devices in a resource device pool based on the plurality of resource devices;
performing a latency analysis on the available resource devices to obtain a plurality of resource device combinations and a total latency cost of each resource device combination,
wherein the total latency cost of each resource device combination comprises a number of units of latency,
wherein the number of units of latency is associated with a number of switch fabrics used to connect a first resource device of a resource device combination to a second resource device of the resource device combination,
wherein each switch fabric comprises a series of crossbar switches; and

selecting the resource device combination of the plurality of resource device combinations based on the total latency cost of each resource device combination, wherein the resource device combination comprises a second plurality of resource devices and wherein each of the second plurality of resource devices is one of the plurality of resource devices.

2. The method of claim 1 , further comprising:
allocating the second plurality of resource devices based on the selecting; and
updating a resource allocation master list based on the allocating.

3. The method of claim 1 , wherein performing the latency analysis comprises:
identifying the resource device combination;
identifying a latency cost of a pair of resource devices in the resource device combination; and
calculating a total latency cost of the resource device combination based at least on the latency cost of the pair of resource devices.

4. The method of claim 1 , wherein the second plurality of resource devices implement a workload.

5. The method of claim 4 , wherein the workload is associated with an infrastructure persona.

6. The method of claim 1 , wherein selecting the resource device combination comprises:
identifying a lowest total latency cost; and
making a determination that the resource device combination is associated with the lowest total latency cost.

7. A non-transitory computer readable medium comprising computer readable program code, which when executed by a computer processor enables the computer processor to perform a method for managing data, the method comprising:
obtaining, by a management module, a workload generation request, wherein the workload generation request specifies a plurality of resource devices;
identifying available resource devices in a resource device pool based on the plurality of resource devices;
performing a latency analysis on the available resource devices to obtain a plurality of resource device combinations and a total latency cost of each resource device combination,
wherein the total latency cost of each resource device combination comprises a number of units of latency,
wherein the number of units of latency is associated with a number of switch fabrics used to connect a first resource device of a resource device combination to a second resource device of the resource device combination,
wherein each switch fabric comprises a series of crossbar switches; and

selecting the resource device combination of the plurality of resource device combinations based on the total latency cost of each resource device combination, wherein the resource device combination comprises a second plurality of resource devices and wherein each of the second plurality of resource devices is one of the plurality of resource devices.

8. The non-transitory computer readable medium of claim 7 , the method further comprising:
allocating the second plurality of resource devices based on the selecting; and
updating a resource allocation master list based on the allocating.

9. The non-transitory computer readable medium of claim 7 , wherein performing the latency analysis comprises:
identifying the resource device combination;
identifying a latency cost of a pair of resource devices in the resource device combination; and
calculating a total latency cost of the resource device combination based at least on the latency cost of the pair of resource devices.

10. The non-transitory computer readable medium of claim 7 , wherein the second plurality of resource devices implement a workload.

11. The non-transitory computer readable medium of claim 10 , wherein the workload is associated with an infrastructure persona.

12. The non-transitory computer readable medium of claim 7 , wherein selecting the resource device combination comprises:
identifying a lowest total latency cost; and
making a determination that the resource device combination is associated with the lowest total latency cost.

13. A system, comprising:
a processor; and
memory comprising instructions, which when executed by the processor, perform a method, the method comprising:
obtaining, by a management module, a workload generation request, wherein the workload generation request specifies a plurality of resource devices;
identifying available resource devices in a resource device pool based on the plurality of resource devices;
performing a latency analysis on the available resource devices to obtain a plurality of resource device combinations and a total latency cost of each resource device combination,
wherein the total latency cost of each resource device combination comprises a number of units of latency,
wherein the number of units of latency is associated with a number of switch fabrics used to connect a first resource device of a resource device combination to a second resource device of the resource device combination,
wherein each switch fabric comprises a series of crossbar switches; and

selecting the resource device combination of the plurality of resource device combinations based on the total latency cost of each resource device combination, wherein the resource device combination comprises a second plurality of resource devices and wherein each of the second plurality of resource devices is one of the plurality of resource devices.

14. The system of claim 13 , the method further comprising:
allocating the second plurality of resource devices based on the selecting; and
updating a resource allocation master list based on the allocating.

15. The system of claim 13 , wherein performing the latency analysis comprises:
identifying the resource device combination;
identifying a latency cost of a pair of resource devices in the resource device combination; and
calculating a total latency cost of the resource device combination based at least on the latency cost of the pair of resource devices.

16. The system of claim 13 , wherein the second plurality of resource devices implement a workload.

17. The system of claim 13 , wherein selecting the resource device combination comprises:
identifying a lowest total latency cost; and
making a determination that the resource device combination is associated with the lowest total latency cost.
