Abstract

A method may include detecting, by a computing device based on a problem signature, that a system has experienced a problem that is associated with the problem signature, wherein the problem signature comprises a specification of a pattern of events indicative of the particular problem experienced by at least one other system; determining that the particular problem violates an operational policy of the system; and deploying, without user intervention, one or more corrective measures that modify the system to resolve the problem.

First claim

What is claimed is:

1. A method comprising:
detecting, by a cloud based storage system services module based on a problem signature, that a system has experienced a problem that is associated with the problem signature, wherein the problem signature comprises a specification of a pattern of events indicative of the particular problem experienced by at least one other system;
determining that the particular problem violates an operational policy of the system; and
deploying, without user intervention, one or more corrective measures that modify the system to resolve the problem.

2. The method of claim 1 , wherein the operational policy specifies at least one requirement for an operational metric of the system, and wherein the operational policy of the system further comprises a specification of a requirement for high availability.

3. The method of claim 1 , wherein the operational policy specifies at least one requirement for an operational metric of the system, and wherein the operational policy of the system further comprises a specification of a requirement for failover availability.

4. The method of claim 1 , wherein the operational policy specifies at least one requirement for an operational metric of the system, and wherein the operational policy of the system further comprises a specification of a requirement for a minimum data reduction ratio.

5. The method of claim 1 , wherein the operational policy specifies at least one requirement for an operational metric of the system, and wherein the operational policy of the system further comprises a specification of a requirement for a minimum input/output latency.

6. The method of claim 1 , wherein the operational policy specifies at least one requirement for an operational metric of the system, and wherein the operational policy of the system further comprises a specification of a requirement for a minimum replication throughput.

7. The method of claim 1 , wherein the operational policy specifies at least one requirement for an operational metric of the system, and wherein the operational policy of the system further comprises a specification of a requirement for data retention.

8. An apparatus, the apparatus comprising a computer processor, a computer memory operatively coupled to the computer processor, the computer memory having disposed within it computer program instructions that, when executed by the computer processor, cause the apparatus to carry out the steps of:
detecting, by a cloud based storage system services module based on a problem signature, that a system has experienced a problem that is associated with the problem signature, wherein the problem signature comprises a specification of a pattern of events indicative of the problem experienced by at least one other system;
determining that the problem violates an operational policy of the system; and
deploying, without user intervention and based on the detecting and the determining, one or more corrective measures that modify the system to resolve the problem.

9. The apparatus of claim 8 , wherein the operational policy of the system further comprises a specification of a requirement for high availability.

10. The apparatus of claim 8 , wherein the operational policy of the system further comprises a specification of a requirement for failover availability.

11. The apparatus of claim 8 , wherein the operational policy of the system further comprises a specification of a requirement for a minimum data reduction ratio.

12. The apparatus of claim 8 , wherein the operational policy of the system further comprises a specification of a requirement for a minimum input/output latency.

13. The apparatus of claim 8 , wherein the operational policy of the system further comprises a specification of a requirement for a minimum replication throughput.

14. The apparatus of claim 8 , wherein the operational policy of the system further comprises a specification of a requirement for data retention.

15. A non-transitory computer-readable medium storing a cloud based storage system services module that comprises instructions that, when executed, direct a processor to carry out the steps of:
detecting that a system has experienced a problem that is associated with a problem signature, wherein the problem signature comprises a specification of a pattern of events indicative of the problem experienced by at least one other system;
determining that the problem violates an operational policy of the system; and
deploying, without user intervention, one or more corrective measures that modify the system to resolve the problem.

16. The non-transitory computer-readable medium of claim 15 , wherein the operational policy of the system further comprises a specification of a requirement for high availability.

17. The non-transitory computer-readable medium of claim 15 , wherein the operational policy of the system further comprises a specification of a requirement for failover availability.

18. The non-transitory computer-readable medium of claim 15 , wherein the operational policy of the system further comprises a specification of a requirement for a minimum data reduction ratio.

19. The non-transitory computer-readable medium of claim 15 , wherein the operational policy of the system further comprises a specification of a requirement for a minimum input/output latency.

20. The non-transitory computer-readable medium of claim 15 , wherein the operational policy of the system further comprises a specification of a requirement for a minimum replication throughput.
