Abstract

An approach is provided for determining disaster recovery capacity. A simulation hypervisor receives streaming metric data, which represents the current production workload of a primary site, from the primary site. The metric data is combined with production data of the backup site by the simulation hypervisor to simulate a recovery event. Using data from the simulating, disaster recovery planning can be performed.

Claims

1. A method for determining disaster recovery capacity, comprising:

receiving, by a simulation hypervisor, streaming metric data from a primary site, the streaming metric data representing a current production workload of the primary site;

simulating, by the simulation hypervisor, a recovery event on a backup site by combining the metric data with production data of the backup site; and

performing disaster planning based on the simulating.

2. The method of claim 1, wherein the receiving and the simulating are performed in real time.

3. The method of claim 1, wherein the streaming metric data is received from a hypervisor module on the primary site.

4. The method of claim 1, wherein the primary site and the backup site are geographically distant.

5. The method of claim 1, further comprising performing capacity planning based on the simulating.

6. The method of claim 1, wherein the simulating further comprises:

designating an application on the primary site as a lower priority application; and

assuming a dormant state for the lower priority application when performing the simulating.

7. The method of claim 1, further comprising:

configuring a hardware component to execute the simulation hypervisor; and

installing the hardware component on a site.

8. The method of claim 1, further comprising:

installing a simulation hypervisor on a backup site,

wherein the simulating is run in a background of the backup site.

9. A system for determining disaster recovery capacity, comprising:

a computer device having a simulation hypervisor installed theron, the simulation hypervisor performing a method, comprising;

receiving, by the simulation hypervisor, streaming metric data from a primary site, the streaming metric data representing a current production workload of the primary site;

simulating, by the simulation hypervisor, a recovery event on a backup site by combining the metric data with production data of the backup site; and

performing disaster planning based on the simulating.

10. The system of claim 9, wherein the receiving and the simulating are performed in real time.

11. The system of claim 9, wherein the streaming metric data is received from a hypervisor module on the primary site.

12. The system of claim 9, wherein the primary site and the backup site are geographically distant.

13. The system of claim 9, wherein the method further comprises performing capacity planning based on the simulating.

14. The system of claim 9, wherein the simulating further comprises:

designating an application on the primary site as a lower priority application; and

15. The system of claim 9, further comprising:

configuring a hardware component to execute the simulation hypervisor; and

installing the hardware component on a site.

16. The system of claim 9,

wherein the computer device is the backup site, and

wherein the simulating is run in a background of the backup site.

17. A computer program product embodied in a computer readable storage medium that implements a method for determining disaster recovery capacity, the method comprising:
