Adaptive QoS maximum latency for volume when IO is below its expected IO limit

Last Updated:

Applies to

  • ONTAP 9
  • Adaptive QoS (AQoS)


  • AQoS maximum latency seen when workload IO is less then configured maximum
  • Volumes in the cluster show a problem where AQoS should be granting more IO than it apparently is
  • Clients report filesysem mounting failures on NetApp volume (even for smaller volumes) associated with high latency reported from QOS limit
