Support for ONTAP QoS throughput floors

You can use storage quality of service (QoS) to guarantee that performance of critical workloads is not degraded by competing workloads. ONTAP has had the ability to create QoS policies in way to specify throughput ceilings on workloads so that they can effectively compete for the back-end storage. ONTAP 9.0 allows specifying "min" values for QoS specs alongside "max" values. You can set a throughput ceiling on a competing workload to limit its impact on system resources, or set a throughput floor for a critical workload, ensuring that it meets minimum throughput targets, regardless of demand by competing workloads. You can even set a ceiling and floor for the same workload.
