Target IOPS start being smaller than maxIOPS when the system decides sacrificing maxIOPS to guarantee minIOPS of all volumes on a node. AIQ Collector is collecting last 500 ms of the throttle information every 60 seconds from SolidFire Storage Cluster. Please refer to NetApp SolidFire Quality of Service (QoS) for understanding how QoS works in Element Software.
