Abstract

In general, in one aspect, the invention relates to a method for managing performances of services, the method comprising: generating subsystem groups, wherein each subsystem group of the subsystem groups comprises a plurality of subsystems, wherein each subsystem group is associated with one a plurality of services, wherein the subsystem groups are generated using per-service subsystem requirements; and performing at least one of the plurality of services using a subsystem group of the subsystem groups.

First claim

What is claimed is:

1. A method for managing performances of services, the method comprising:
generating subsystem groups, wherein each subsystem group of the subsystem groups comprises a plurality of subsystems, wherein each subsystem group is associated with one of a plurality of services, wherein the subsystem groups are generated using per-service subsystem requirements,
wherein the plurality of services are performed based on policies and service priorities specified by the policies;

performing, based on each subsystem's assigned concurrency, at least one of the plurality of services using a subsystem group of the subsystem groups, wherein a subsystem's concurrency specifies a number of concurrent services that the subsystem is able to perform; and
obtaining subsystem statistics for each of the plurality of subsystems,
wherein the subsystem statistics specify at least one selected from a group consisting of a number of operations per policy performed by each of the plurality of subsystems, and a resource allocation for each of the plurality of subsystems,
wherein the subsystem statistics and the service priorities are used to generate a feedback with respect to a service performance level of each of the plurality of subsystems by managing each subsystem's concurrency.

2. The method of claim 1 , wherein the plurality of subsystems comprises one selected from a group consisting of:
a host data subsystem,
a storages data subsystem,
a network subsystem,
a metadata subsystem, and
a compute subsystem.

3. The method of claim 2 , wherein the plurality of services comprises at least one selected from a group consisting of:
a backup service;
a replication service;
a tiering service; and
a disaster recovery service.

4. The method of claim 1 , further comprising:
determining a per-service performance metric for each service based on the subsystem statistics.

5. The method of claim 4 ,
wherein the per-service performance metric for a service of the plurality of services indicates that the service is operating below an expected performance level;
further comprising:
sending, a notification to a user, when the per-service performance metric for a service of the plurality of services indicates that the service is operating below an expected performance level.

6. The method of claim 5 , wherein the notification specifies a cause of the service is operating below an expected performance level.

7. The method of claim 6 , further comprising:
removing a subsystem from a subsystem group associated with the service, wherein the subsystem group is specified as the cause in the notification; and
allocating another subsystem to the subsystem group.

8. A non-transitory computer readable medium comprising computer readable program code, which when executed by a computer processor enables the computer processor to perform a method for managing performances of services, the method comprising:
generating subsystem groups, wherein each subsystem group of the subsystem groups comprises a plurality of subsystems, wherein each subsystem group is associated with one of a plurality of services, wherein the subsystem groups are generated using per-service subsystem requirements,
wherein the plurality of services are performed based on policies and service priorities specified by the policies;

performing, based on each subsystem's assigned concurrency, at least one of the plurality of services using a subsystem group of the subsystem groups, wherein a subsystem's concurrency specifies a number of concurrent services that the subsystem is able to perform; and
obtaining subsystem statistics for each of the plurality of subsystems,
wherein the subsystem statistics specify at least one selected from a group consisting of a number of operations per policy performed by each of the plurality of subsystems, and a resource allocation for each of the plurality of subsystems,

wherein the subsystem statistics and the service priorities are used to generate a feedback with respect to a service performance level of each of the plurality of subsystems by managing each subsystem's concurrency.

9. The non-transitory computer readable medium of claim 8 , wherein the plurality of subsystems comprises one selected from a group consisting of:
a host data subsystem,
a storages data subsystem,
a network subsystem,
a metadata subsystem, and
a compute subsystem.

10. The non-transitory computer readable medium of claim 9 , wherein the plurality of services comprises at least one selected from a group consisting of:
a backup service;
a replication service;
a tiering service; and
a disaster recovery service.

11. The non-transitory computer readable medium of claim 8 , the method further comprising:
determining a per-service performance metric for each service based on the subsystem statistics.

12. The non-transitory computer readable medium of claim 11 ,
wherein the per-service performance metric for a service of the plurality of services indicates that the service is operating below an expected performance level;
where the method further comprises:
sending, a notification to a user, when the per-service performance metric for a service of the plurality of services indicates that the service is operating below an expected performance level.

13. The non-transitory computer readable medium of claim 12 , wherein the notification specifies a cause of the service is operating below an expected performance level.

14. The non-transitory computer readable medium of claim 13 , further comprising:
removing a subsystem from a subsystem group associated with the service, wherein the subsystem group is specified as the cause in the notification; and
allocating another subsystem to the subsystem group.

15. A data protection manager, comprising:
a processor and memory, and configured to:
generate subsystem groups, wherein each subsystem group of the subsystem groups comprises a plurality of subsystems, wherein each subsystem group is associated with one of a plurality of services, wherein the subsystem groups are generated using per-service subsystem requirements,
wherein the plurality of services are performed based on policies and service priorities specified by the policies;
perform, based on each subsystem's assigned concurrency, at least one of the plurality of services using a subsystem group of the subsystem groups, wherein a subsystem's concurrency specifies a number of concurrent services that the subsystem is able to perform; and
obtaining subsystem statistics for each of the plurality of subsystems,
wherein the subsystem statistics specify at least one selected from a group consisting of a number of operations per policy performed by each of the plurality of subsystems, and a resource allocation for each of the plurality of subsystems,
wherein the subsystem statistics and the service priorities are used to generate a feedback with respect to a service performance level of each of the plurality of subsystems by managing each subsystem's concurrency.

16. The data protection manager of claim 15 , wherein the plurality of subsystems comprises one selected from a group consisting of:
a host data subsystem,
a storages data subsystem,
a network subsystem,
a metadata subsystem, and
a compute subsystem.

17. The data protection manager of claim 16 , wherein the plurality of services comprises at least one selected from a group consisting of:
a backup service;
a replication service;
a tiering service; and
a disaster recovery service.
