Abstract

Embodiments for managing resources in a tiered data storage system, by a processor device. In response to differing business priorities for executing workloads by a workload manager, a resource plan is generated by an administrator of the workload manager. The resource plan defines what resources of the storage system are allocated to a particular group of tenants and at what time the workloads of the particular group are executed, thereby optimizing utilization of the resources of the storage system. A time period of which a particular one of a plurality of storage tiers of the tiered data storage system is allocated for use by the respective one of the tenants is defined by an administrator, where a peak demand summed over all of tenants is allowed to exceed a total capacity of each individual one of the plurality of storage tiers.

Claims

1. A method for managing resources in a tiered data storage system, by a processor device, comprising:

generating a resource plan by an administrator of a workload manager, wherein the resource plan defines what resources of the storage system are allocated to a particular group of tenants and at what time the workloads of the particular group are executed, thereby optimizing utilization of the resources of the storage system; and

defining, by the administrator, a time period of which a particular one of a plurality of storage tiers of the tiered data storage system is allocated for use by the respective one of the tenants, wherein a peak demand summed over all of tenants is allowed to exceed a total capacity of each individual one of the plurality of storage tiers.

2. The method of claim 1, wherein the administrator defines a quantity of the particular one of the plurality of storage tiers to be allocated for use by the respective one of the tenants.

3. The method of claim 1, further including submitting a storage portion of the resource plan to an optimization policy generator, wherein the optimization policy generator, over a predetermined timeframe, translates the storage portion of the resource plan into placement and migration policies to be executed for data stored in the storage system.

4. The method of claim 3, further including migrating or initially placing the data, by the storage system, in at least one of the plurality of storage tiers in accordance with the placement and migration policies received by the optimization policy generator.

5. The method of claim 1, further including dispatching each of the workloads by the workload manager to at least one of a plurality of computers, wherein the storage system provides capacity of each of the plurality of storage tiers aligned with the resource plan maintained by the workload manager.

6. The method of claim 1, wherein the resources are selected from a list comprising at least Central Processing Unit (CPU), memory, and storage resources;

and

the resource plan is associated with business requirements or a Service Level Agreement (SLA).

7. A system for managing resources in a tiered data storage system, the system comprising:

a processor device executing instructions stored in a memory, wherein the processor device;

generates a resource plan by an administrator of a workload manager, wherein the resource plan defines what resources of the storage system are allocated to a particular group of tenants and at what time the workloads of the particular group are executed, thereby optimizing utilization of the resources of the storage system; and

defines, according to input by the administrator, a time period of which a particular one of a plurality of storage tiers of the tiered data storage system is allocated for use by the respective one of the tenants, wherein a peak demand summed over all of tenants is allowed to exceed a total capacity of each individual one of the plurality of storage tiers.

8. The system of claim 7, wherein the administrator defines a quantity of the particular one of the plurality of storage tiers to be allocated for use by the respective one of the tenants.

9. The system of claim 7, wherein the processor device submits a storage portion of the resource plan to an optimization policy generator, wherein the optimization policy generator, over a predetermined timeframe, translates the storage portion of the resource plan into placement and migration policies to be executed for data stored in the storage system.

10. The system of claim 9, wherein the processor device migrates or initially places the data, by the storage system, in at least one of the plurality of storage tiers in accordance with the placement and migration policies received by the optimization policy generator.

11. The system of claim 7, wherein the processor device dispatches each of the workloads by the workload manager to at least one of a plurality of computers, wherein the storage system provides capacity of each of the plurality of storage tiers aligned with the resource plan maintained by the workload manager.

12. The system of claim 7, wherein the resources are selected from a list comprising at least Central Processing Unit (CPU), memory, and storage resources;

and

the resource plan is associated with business requirements or a Service Level Agreement (SLA).

13. A computer program product for managing resources in a tiered data storage system, by a processor device, the computer program product embodied on a non-transitory computer-readable storage medium having computer-readable program code portions stored therein, the computer-readable program code portions comprising:

an executable portion that generates a resource plan by an administrator of a workload manager, wherein the resource plan defines what resources of the storage system are allocated to a particular group of tenants and at what time the workloads of the particular group are executed, thereby optimizing utilization of the resources of the storage system; and

an executable portion that defines, according to input by the administrator, a time period of which a particular one of a plurality of storage tiers of the tiered data storage system is allocated for use by the respective one of the tenants, wherein a peak demand summed over all of tenants is allowed to exceed a total capacity of each individual one of the plurality of storage tiers.

14. The computer program product of claim 13, wherein the administrator defines a quantity of the particular one of the plurality of storage tiers to be allocated for use by the respective one of the tenants.

15. The computer program product of claim 13, further including an executable portion that submits a storage portion of the resource plan to an optimization policy generator, wherein the optimization policy generator, over a predetermined timeframe, translates the storage portion of the resource plan into placement and migration policies to be executed for data stored in the storage system.

16. The computer program product of claim 15, further including an executable portion that migrates or initially places the data, by the storage system, in at least one of the plurality of storage tiers in accordance with the placement and migration policies received by the optimization policy generator.

17. The computer program product of claim 13, further including an executable portion that dispatches each of the workloads by the workload manager to at least one of a plurality of computers, wherein the storage system provides capacity of each of the plurality of storage tiers aligned with the resource plan maintained by the workload manager.

18. The computer program product of claim 13, wherein the resources are selected from a list comprising at least Central Processing Unit (CPU), memory, and storage resources;

and

the resource plan is associated with business requirements or a Service Level Agreement (SLA).
