Manage Quality of Service policies

Contributors amgrissino ntap-bmegan Download PDF of this page

A Quality of Service (QoS) policy enables you to create and save a standardized quality of service setting that can be applied to many volumes. You can create, edit, and delete QoS policies from the QoS Policies page on the Management tab.

If you are using QoS policies, do not use custom QoS on a volume. Custom QoS will override and adjust QoS policy values for volume QoS settings.

Create a QoS policy

You can create QoS policies and apply them when creating volumes.

  1. Select Management > QoS Policies.

  2. Click Create QoS Policy.

  3. Enter the Policy Name.

  4. Enter theMin IOPS, Max IOPS, and Burst IOPS values.

  5. Click Create QoS Policy.

Edit a QoS policy

You can change the name of an existing QoS policy or edit the values associated with the policy. Changing a QoS policy affects all volumes associated with the policy.

  1. Select Management > QoS Policies.

  2. Click the Actions icon for the QoS policy you want to edit.

  3. In the resulting menu, selectEdit.

  4. In the Edit QoS Policy dialog box, modify the following properties as required:

    • Policy Name

    • Min IOPS

    • Max IOPS

    • Burst IOPS

  5. Click Save Changes.

Delete a QoS policy

You can delete a QoS policy if it is no longer needed. When you delete a QoS policy, all volumes associated with the policy maintain the QoS settings but become unassociated with a policy.

If you are trying instead to disassociate a volume from a QoS policy, you can change the QoS settings for that volume to custom.
  1. Select Management > QoS Policies.

  2. Click the Actions icon for the QoS policy you want to delete.

  3. In the resulting menu, select Delete.

  4. Confirm the action.
