Abstract

Methods and systems described herein implement an SLA-based dynamic provisioning of storage for virtualized applications or virtual machines (VMs) on shared storage. The shared storage can be located behind a storage area network (SAN) or on a virtual distributed storage system that aggregates storage across direct attached storage in the server or host, or behind the SAN or a WAN.

Claims

1. A method for provisioning of storage for virtualized applications by meeting at least one service level agreement (SLA), wherein the SLA pertains to the operation of an application, the method comprising:

identifying at least one resource requirement in the SLA for a first application;

quantifying the at least one resource associated with the at least one resource requirement that is used by a first application when the first application is running; and

adding a second application when the difference between the resource requirement of the SLA for the first application and the at least one resource used by the first application accommodates a resource requirement for the second application.

2. The method of claim 1 and further comprising quantifying the first resource used by the second application when the second application is running.

9. The method of claim 1, wherein the at least one resource is memory.

10. The method of claim 1, wherein the at least one resource is storage capacity.

11. The method of claim 1, wherein the at least one resource is storage performance.

12. The method of claim 1, wherein the SLA is enforced in a hypervisor.

13. The method of claim 1, wherein the SLA is enforced in a storage network.

14. The method of claim 1, wherein the SLA is enforced in a storage system.

15. The method of claim 1 wherein the at least one resource is at least one property of a logical storage volume associated with the first application.

16. The method of claim 1 and further comprising modifying the resource allocation of a logical storage volume associated with the first application in order to accommodate the second application.

17. The method of claim 1 and further comprising moving a logical storage volume associated with the first application when the SLA associated with the first application cannot be met.

3. A method for dynamic provisioning of storage for virtualized applications by meeting at least one SLA, wherein the SLA pertains to the operation of the applications, the method comprising:

running a first application on a shared data storage;

identifying at least one resource requirement of the SLA for the first application;

quantifying a resource required by the SLA used by the first application when the first application is running; and

adding a second application on the shared data storage when the difference between the resource requirement of the SLA for the first application and the resources used by the first application accommodates a resource requirement for the second application.

4. The method of claim 21, wherein the SLA is enforced in a hypervisor.

5. The method of claim 21 wherein the SLA is enforced in a storage network.

6. The method of claim 21, wherein the SLA is enforced in a storage system.

7. The method of claim 3 and further comprising modifying at least one property of a logical storage volume associated with the first application, wherein the logical storage volume is associated with the shared data storage.

8. The method of claim 3 and further comprising moving the logical storage volume associated with the first application.

21. The method of claim 3 and further comprising enforcing the SLA.

18. A method for dynamic provisioning of storage for virtualized applications running a first application on a virtual machine, the method comprising:

locating a shared data storage on which a logical storage volume can be created for a first application;

identifying a SLA associated with the first application;

provisioning the logical storage volume on which to run the first application;

monitoring the SLA;

enforcing the SLA.

19. The method of claim 18, wherein the enforcing comprises allocating additional resources in the shared data storage to the logical storage volume on which the first application is running.

20. The method of claim 18, wherein the enforcing of the SLA comprises allocating resources from a second application to the first application.
