Assigning volumes to Storage QoS

You can limit the throughput of FlexVol volumes and FlexGroup volumes by assigning them to storage Quality of Service (QoS) policy groups. You can assign storage QoS for new volumes, or you can modify the storage QoS details of the volumes that are already assigned to a policy group by using Storage Manager.

About this task

  • You can assign storage QoS only to read/write (rw) volumes that are online.

  • You cannot assign storage QoS to a volume if the following storage objects are assigned to a policy group:

    • Parent storage virtual machine (SVM) of the volume

    • Child LUNs of the volume

    • Child files of the volume

  • You can assign storage QoS or modify the QoS details for a maximum of 10 volumes simultaneously.

  1. Click Storage > Volumes.
  2. Select the required volume and click the more icon .
  3. Select Edit.
  4. Select Enforce performance limits.
  5. Specify whether you want to use an existing limit or a new limit.

    • If you want to use an existing limit, select extreme, performance, or value.

    • If you want to create a new limit, specify the policy group name, IOPs guarantee, bandwidth limit, and IOPs limit.

  6. Click Save.
