Patent ID: 7606892

Claim:
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.
