Abstract

A method and system of supporting a computer network resource pool. In one embodiment of the invention, a resource pool sparing-plan and a resource pool support-plan are selected; for the selected resource sparing-plan and resource support-plan, the probability that all resources in the resource pool are operating properly is determined. The method is repeated to generate results from which an acceptable support-plan and a sparing-plan is chosen for implementation.

Claims

1. A method of supporting a computer network resource pool, comprising:

a processor performing the steps of;

selecting a first and a second resource pool sparing-plans for said resource pool;

selecting a first and a second resource pool support-plans for said resource pool; and

determining a first probability that all resources in said resource pool are operating properly for said first resource sparing-plan and said first resource support-plan and a second probability that all resources in said resource pool are operating properly for said second resource sparing-plan and said second resource support-plan, wherein said first probability and said second probability enable implementation of a particular resource pool support-plan from said first resource pool support-plan and said second resource pool support-plan;

wherein said determining said first probability that all resources in said resource pool are operating properly for said first resource sparing-plan and said first resource support-plan, comprises applying a mathematical model for correlating resource availability in said resource pool, failure rates and recovery rates of said resources, reprovisioning time needed to swap a healthy spare resource for an unhealthy production pool resource, and a plurality of support-plans for said resources.

2. The method of claim 1, wherein said resource pool comprises a pool of production resources in said network.

3. The method of claim 1, wherein said sparing-plans comprise plans for the provisioning of spare resources in said network.

4. The method of claim 1, wherein said support-plans comprise plans for provisioning of support for said resource pool.

5. The method of claim 1, wherein said resource pool comprises application servers, database servers, data storage, disk drives, load balancers and processors communicatively coupled to said network.

6. The method of claim 1, wherein said mathematical model comprises applying a Markov chain steady-state solution analysis methodology.

7. The method of claim 1, wherein said selecting a first and a second resource pool sparing-plans, said selecting a first and a second resource pool support plan, said determining, and said implementation are performed automatically on a computer system.

8. The method of claim 1, wherein said computer network is communicatively coupled with a utility data center.

9. The method of claim 1, further comprising implementing said particular resource pool support-plan and a particular resource pool sparing-plan by selecting a probability that all resources in said resource pool are operating properly.

10. A computer data center comprising:

a bus for communicating information;

a processor coupled with said bus for processing said information; and

a computer readable media coupled with said bus and comprising instructions for implementing a method of supporting a computer network resource pool, said method comprising;

selecting a first and a second resource pool sparing-plans for said resource pool;

selecting a first and a second resource pool support-plans for said resource pool; and

determining a first probability that all resources in said resource pool are operating properly for said first resource sparing-plan and said first resource support-plan and a second probability that all resources in said resource pool are operating properly for said second resource sparing-plan and said second resource support-plan, wherein said first probability and said second probability enable implementation of a particular resource pool support-plan from said first resource pool support-plan and said second resource pool support plan;

wherein said determining said first probability that all resources in said resource pool are operating properly for said first resource sparing-plan and said first resource support-plan, comprises applying a mathematical model for correlating resource availability in said resource pool, failure rates and recovery rates of said resources, reprovisioning time needed to swap in healthy spare resource for an unhealthy production pool resource, and a plurality of support-plans for said resources.

11. The computer data center of claim 10, wherein said resource pool comprises a pool of production resources in said network.

12. The computer data center of claim 10, wherein said sparing-plans comprise plans for the provisioning of spare resources in said network.

13. The computer data center of claim 10, wherein said support-plans comprise plans for provisioning of support for said resource pool.

14. The computer data center of claim 10, wherein said resource pool comprises application servers, database servers, data storage, disk drives, load balancers and processors communicatively coupled to said network.

15. The computer data center of claim 10, wherein said mathematical model comprises applying a Markov chain steady-state solution analysis methodology.

16. The computer data center of claim 10 wherein said selecting a first and a second resource pool sparing-plans, said selecting a first and a second resource pool support plan, said determining, and said implementation are performed automatically on a computer system.

17. A computer-useable medium having computer readable code stored thereon for causing a utility data center to perform a method of supporting a computer network resource pool, said method comprising:

selecting a first and a second resource pool sparing-plans for said resource pool;

selecting a first and a second resource pool support-plans for said resource pool; and

determining a first probability that all resources in said resource pool are operating properly for said first resource sparing-plan and said first resource support-plan and a second probability that all resources in said resource pool are operating properly for said second resource sparing-plan and said second resource support-plan, wherein said first probability and said second probability enable implementation of a particular resource pool support-plan from said first resource pool support-plan and said second resource pool support-plan;

wherein said determining said first probability that all resources in said resource pool are operating properly for said first resource sparing-plan and said first resource support-plan, comprises applying a mathematical model for correlating resource availability in said resource pool, failure rates and recovery rates of said resources, reprovisioning time needed to swap in healthy spare resource for an unhealthy production pool resource, and a plurality of support-plans for said resources.

18. The computer-useable medium of claim 17, wherein said resource pool comprises a pool of production resources in said network.

19. The computer-useable medium of claim 17, wherein said sparing-plans comprise plans for the provisioning of spare resources in said network.

20. The computer-useable medium of claim 17, wherein said support-plans comprise plans for provisioning of support for said resource pool.

21. The computer-useable medium of claim 17, wherein said resource pool comprises application servers, database servers, data storage, disk drives, load balancers and processors communicatively coupled to said network.

22. The computer-useable medium of claim 17, where said mathematical model comprises applying a Markov chain steady-state solution analysis methodology.

23. The computer-useable medium of claim 17, wherein said computer network is communicatively coupled with a utility data center.
