Workload planning with quality-of-service (‘QOS’) integration
Workload planning with quality-of-service (‘QoS’) integration, including: determining, for each of a plurality of entities, one or more QoS thresholds associated with the entity; determining, for each of the plurality of entities, one or more resource utilization levels associated with the entity; and determining, in dependence upon the one or more QoS thresholds associated with the plurality of entities, the one or more resource utilization levels associated with the plurality of entities, and one or more overprovisioning factors associated with the storage system, a risk factor that identifies the likelihood that one or more system resources will be overconsumed by the plurality of entities.
1. A method of workload planning with quality-of-service (‘QoS’) integration, the method comprising:
determining, for each of a plurality of entities, one or more QoS thresholds associated with the entity;
determining, for each of the plurality of entities, one or more resource utilization levels associated with the entity;
determining, in dependence upon the one or more QoS thresholds associated with the plurality of entities, the one or more resource utilization levels associated with the plurality of entities, and one or more overprovisioning factors associated with a storage system, a risk factor that identifies the likelihood that one or more system resources will be overconsumed by the plurality of entities; and
adjusting, in dependence upon the risk factor, one or more of the QoS thresholds until the risk factor falls within a desired risk tolerance.
2. The method of claim 1 further comprising:
generating, in dependence upon the risk factor, a recommendation; and
issuing the recommendation to a user.
3. The method of claim 1 further comprising:
receiving a request to support an additional entity;
determining, in dependence a projected risk factor, whether to support the additional entity.
4. The method of claim 1 further comprising receiving the desired risk tolerance.
5. The method of claim 1 further comprising migrating an entity from the storage system to a second storage system.
6. The method of claim 1 wherein determining one or more resource utilization levels associated with the entity further comprises:
identifying a similar entity; and
determining one or more resource utilization levels associated with the similar entity.
7. An apparatus for workload planning with quality-of-service (‘QoS’) integration, 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:
determining, for each of a plurality of entities, one or more QoS thresholds associated with the entity;
determining, for each of the plurality of entities, one or more resource utilization levels associated with the entity;
determining, in dependence upon the one or more QoS thresholds associated with the plurality of entities, the one or more resource utilization levels associated with the plurality of entities, and one or more overprovisioning factors associated with a storage system, a risk factor that identifies the likelihood that one or more system resources will be overconsumed by the plurality of entities; and
adjusting, in dependence upon the risk factor, one or more of the QoS thresholds until the risk factor falls within a desired risk tolerance.
8. The apparatus of claim 7 further comprising computer program instructions that, when executed by the computer processor, cause the apparatus to carry out the steps of:
generating, in dependence upon the risk factor, a recommendation; and
issuing the recommendation to a user.
9. The apparatus of claim 7 further comprising computer program instructions that, when executed by the computer processor, cause the apparatus to carry out the steps of:
receiving a request to support an additional entity;
determining, in dependence a projected risk factor, whether to support the additional entity.
10. The apparatus of claim 7 further comprising computer program instructions that, when executed by the computer processor, cause the apparatus to carry out the step of receiving the desired risk tolerance.
11. The apparatus of claim 7 further comprising computer program instructions that, when executed by the computer processor, cause the apparatus to carry out the step of migrating an entity from the storage system to a second storage system.
12. The apparatus of claim 7 wherein determining one or more resource utilization levels associated with the entity further comprises:
identifying a similar entity; and
determining one or more resource utilization levels associated with the similar entity.
13. A storage system for workload planning with quality-of-service (‘QoS’) integration, the storage system including a computer readable storage medium and a computer processor, the computer readable storage medium including computer program instructions that, when executed by the computer processor, cause the storage system to carry out the steps of:
determining, for each of a plurality of entities, one or more QoS thresholds associated with the entity;
determining, for each of the plurality of entities, one or more resource utilization levels associated with the entity;
determining, in dependence upon the one or more QoS thresholds associated with the plurality of entities, the one or more resource utilization levels associated with the plurality of entities, and one or more overprovisioning factors associated with the storage system, a risk factor that identifies the likelihood that one or more system resources will be overconsumed by the plurality of entities; and
adjusting, in dependence upon the risk factor, one or more of the QoS thresholds until the risk factor falls within a desired risk tolerance.
14. The storage system of claim 13 further comprising computer program instructions that, when executed by the computer processor, cause the storage system to carry out the steps of:
generating, in dependence upon the risk factor, a recommendation; and
issuing the recommendation to a user.
15. The storage system of claim 13 further comprising computer program instructions that, when executed by the computer processor, cause the storage system to carry out the steps of:
receiving a request to support an additional entity;
determining, in dependence a projected risk factor, whether to support the additional entity.
16. The storage system of claim 13 further comprising computer program instructions that, when executed by the computer processor, cause the storage system to carry out the steps of receiving the desired risk tolerance.
17. The storage system of claim 13 wherein determining one or more resource utilization levels associated with the entity further comprises:
identifying a similar entity; and
determining one or more resource utilization levels associated with the similar entity.
