This means the Ceiling is the greater of 1) Expected IOPS, 2) Peak IOPS, or 3) Absolute Minimum IOPS Example: A 10 GB Volume with a default Adaptive QoS "value" policy group will have a Floor of 75 IO...This means the Ceiling is the greater of 1) Expected IOPS, 2) Peak IOPS, or 3) Absolute Minimum IOPS Example: A 10 GB Volume with a default Adaptive QoS "value" policy group will have a Floor of 75 IOPs, not 1.28 IOPs Expected. Above the CPU headroom optimal point on ONTAP 9.7 and above, deadline IOPS will get the same values as below the optimal point and Best Effort IOPS are throttled heavier
