Priority Optimization overview

HPE 3PAR Priority Optimization software provides I/O performance optimization features on HPE 3PAR Storage systems.

These features are installed as part of the HPE Storage OS but require an HPE 3PAR Priority Optimization software license to use. For information about HPE 3PAR Storage platform support, see the HPE SSMC Administrator Guide.

Priority Optimization policies can be created for a storage system, the virtual volume sets on a storage system, and the virtual domains on a storage system. Each policy can specify a priority, latency goal, maximum performance limits and minimum performance goals for the IOPS and bandwidth of the virtual volumes that are covered by the policy. When the limits and goals of a higher priority policy are not met, the storage system automatically throttles (reduces) the IOPS and bandwidth of the virtual volumes that are covered by the lower-priority policies.

Other policy concepts:

• Individual policies can be enabled and disabled.

• A policy for a virtual domain applies to all of the virtual volumes in the domain.

• A policy for a virtual volume set applies to all of the virtual volumes in the set.

• To create a policy for a single virtual volume, the virtual volume must be the only member of a virtual volume set.

• Priority Optimization policies are also known as quality-of-service (QoS) rules.

You can use HPE SSMC to perform many Priority Optimization tasks. Learn more: Storage Optimization screens, views, and actions summary.
