What is the DPO license and how does it affect QoS policies and latency?

Last Updated:

Applies to    

  • ONTAP 9.3 or higher
  • Data Protection Optimized (DPO) License


  • Data Protection Optimized (DPO) functionality increases the amount of concurrent SnapMirror sessions per node, as well as improving SnapMirror performance to the cluster
    • DPO is not intended for use on systems containing production data
  • After upgrading to ONTAP 9.3+ OR creating a new vserver in ONTAP 9.3+ with DPO licensing, new QoS policies with the naming convention <vserver>_dpo_default are generated and applied to the correspondingly named vservers
    • In the example output below, vserver vs4 has a DPO default QoS policy that was automatically generated:
cluster11::> qos policy-group show
Name             Vserver     Class        Wklds Throughput
---------------- ----------- ------------ ----- ------------
vs4_dpo_default  vs4         user-defined 1     100000 IOPS
pg2              vs2         user-defined 2     0-500IOPS
pg5              vs1         user-defined 4     0-300IOPS
pg6              vs0         user-defined 1     0-INF
4 entries were displayed.
  • ONTAP 9.3+ Data Protection Optimized (DPO-licensed or also called DP_Optimized) SnapMirror destination clusters auto-create a <vserver>_dpo_default QoS policy with an auto-configured IOPs limit
    • The intent of these auto-generated QoS policies is to limit the impact of client workload on SnapMirror relationships
  • The QoS policies are applied when a new vserver in a DPO-licensed cluster is created in ONTAP 9.3, or to any vserver without a pre-existing QoS policy applied in a cluster that is subsequently upgraded to ONTAP 9.3
