Abstract

An apparatus and method to automatically activate a reserve resource when the load on a number of active resources (e.g., a number of CPUs or servers) meets a threshold. A resource usage policy specifying at least one threshold and having a corresponding task is compared to a monitored load on the active resource. When the monitored load meets the threshold as specified in the resource usage policy, the corresponding task is performed. For instance, the corresponding task can be to signal an event manager (e.g., a pager), to activate a reserve resource, etc. Once a reserve resource is activated, the load is balanced among the number of active resources and the activated reserve resource. When the load drops below the threshold, the processor can deactivate the reserve resource. In a preferred embodiment, the processor updates a configuration profile for tracking each of the resources. Another embodiment includes charging a fee for monitoring and activation.

Claims

1. A method to automatically activate a reserve hardware component, comprising:

monitoring a load on a number of active resources;

comparing said load to a threshold specified in a resource usage policy; and

automatically activating said reserve hardware component when dictated by said resource usage policy, wherein the threshold specified in said resource usage policy is a rate of active resource consumption.

2. The method of claim 1, further comprising updating said resource usage policy after said reserve hardware component is activated.

3. The method of claim 1, further comprising balancing said load among said number of active resources and said activated reserve hardware component.

4. The method of claim 1, further comprising:

a) monitoring a combined load on said number of active resources and said activated reserve hardware component;

b) comparing said combined load to a second threshold specified in a second resource usage policy;

c) deactivating a hardware component selected from said number of active resources and said activated reserve hardware component when dictated by said second resource usage policy; and

d) indicating that said selected hardware component is deactivated.

5. The method of claim 1, further comprising signaling an event manager based on said monitored load as dictated by said resource usage policy.

6. The method of claim 1, wherein said resource usage policy dictates activating said reserve hardware component when said monitored load exceeds said threshold for a predetermined occurrence.

7. The method of claim 1, wherein said resource usage policy dictates activating said reserve hardware component when said monitored load exceeds said threshold for a period of time.

8. The method of claim 1, wherein said resource usage policy triggers a number of alarms when said threshold is met, and wherein said resource usage policy dictates activating said reserve hardware component when a response to said number of alarms is not received.

9. The method of claim 1, further comprising updating a configuration profile to include said activated reserve hardware component, said update being made in response to said indication that said reserve hardware component is activated.

10. The method of claim 1 further comprising charging a user of said activated reserve hardware component a fee, said charge being made in response to said indication that said reserve hardware component is activated.

11. The method of claim 1, wherein activating said reserve hardware component comprises activating a reserve processor.

12. The method of claim 11, wherein said reserve processor is a component of an active server resource.

13. The method of claim 1, wherein activating said reserve hardware component comprises activating a reserve memory.

14. The method of claim 13, wherein said reserve memory is a component of an active server resource.

15. An apparatus for automatically activating a reserve hardware component, comprising:

at least one computer readable storage media;

a resource usage policy stored on said at least one computer readable storage media; and

computer readable program code stored on said at least one computer readable storage media, said computer readable program code comprising;

program code for monitoring a load on a number of active resources;

program code for comparing said monitored load to a threshold specified in said resource usage policy;

program code for activating said reserve hardware component when dictated by said resource usage policy; and

program code for selecting a reserve hardware component to activate based on a hierarchical resource deployment scheme.

16. The apparatus of claim 15, further comprising program code for indicating that said reserve hardware component has been activated.

17. The apparatus of claim 15, further comprising program code for signaling an event manager based on said monitored load when dictated by said resource usage policy.

18. The apparatus of claim 15, further comprising program code for selecting said reserve hardware component from a pool of reserve resources.

19. The apparatus of claim 15, further comprising:

a) program code for monitoring a combined load on said number of active resources and said activated reserve hardware component;

b) program code for comparing said combined load to a second threshold specified in a second resource usage policy;

c) program code for deactivating a hardware component selected from said number of active resources and said activated reserve hardware component when dictated by said second resource usage policy; and

d) program code for indicating that said selected hardware component is deactivated.

20. The apparatus of claim 19, further comprising program code for returning said deactivated reserve hardware component to a pool of reserve resources.

21. The apparatus of claim 15, further comprising:

a configuration profile stored on said at least one computer readable storage medium; and

program code for updating said configuration profile to track the availability of each said resource.

22. The apparatus of claim 15, wherein said program code for activating said reserve hardware component activates a reserve processor.

23. The apparatus of claim 22, wherein said reserve processor is a component of an active server resource.

24. The apparatus of claim 15, wherein said program code for activating said reserve hardware component activates a reserve memory.

25. The apparatus of claim 24, wherein said reserve memory is a component of an active server resource.

26. The apparatus of claim 15, wherein the threshold specified in said resource usage policy is a rate of active resource consumption.
