Create and manage volume QoS policies

Contributors netapp-pcarriga netapp-dbagwell

A QoS (Quality of Service) policy enables you to create and save a standardized quality of service setting that can be applied to many volumes. The selected cluster must be Element 10.0 or later to use QoS policies; otherwise, QoS policy functions are not available.

Using the plug-in extension point, you can configure and manage QoSSIOC by completing the following tasks:

Create a QoS policy

You can create QoS policies and apply them to volumes that should have equivalent performance.

Note QoSSIOC automation and QoS policies should not be used together. If you are using QoS policies, do not enable QoSSIOC. QoSSIOC will override and adjust QoS values for volume QoS settings.
Steps

  1. From the vCenter Plug-in, open the Management tab:

    • Beginning with Element vCenter plug-in 5.0, select NetApp Element Remote Plugin > Management > Management.

    • For Element vCenter plug-in 4.10 and earlier, select NetApp Element Management > Management.

    Note If two or more clusters are added, ensure that the cluster you intend to use for the task is selected in the navigation bar.

  2. Click the QoS Policies sub-tab.

  3. Click Create QoS Policy.

  4. Enter the Policy Name.

    Tip Use descriptive naming best practices. This is especially important if multiple clusters or vCenter Servers are used in your environment.

  5. Enter the minimum IOPS, maximum IOPS, and burst IOPS values.

  6. Click OK.

Apply a QoS policy to volumes

You can apply an existing QoS policy to multiple volumes. Use this process when you want to bulk apply a policy to one or more volumes.

What you'll need

The QoS policy you want to bulk apply has been created.

Steps

  1. From the vCenter Plug-in, open the Management tab:

    • Beginning with Element vCenter plug-in 5.0, select NetApp Element Remote Plugin > Management > Management.

    • For Element vCenter plug-in 4.10 and earlier, select NetApp Element Management > Management.

    Note If two or more clusters are added, ensure that the cluster you intend to use for the task is selected in the navigation bar.

  2. Click the Volumes sub-tab.

  3. Select the check box for each volume to which you want to apply a QoS policy.

  4. Click Actions.

  5. In the resulting menu, select Apply QoS Policy.

  6. In the dialog box, select the QoS policy from the drop-down list to apply to the selected volumes.

  7. Click OK.

Change the QoS policy association of a volume

You can remove a QoS policy association from a volume or select a different QoS policy or custom QoS.

What you'll need

The volume you want to modify is associated with a QoS policy.

Steps

  1. From the vCenter Plug-in, open the Management tab:

    • Beginning with Element vCenter plug-in 5.0, select NetApp Element Remote Plugin > Management > Management.

    • For Element vCenter plug-in 4.10 and earlier, select NetApp Element Management > Management.

    Note If two or more clusters are added, ensure that the cluster you intend to use for the task is selected in the navigation bar.

  2. Click the Volumes sub-tab.

  3. Select the check box for a volume that contains a QoS policy you want to modify.

  4. Click Actions.

  5. In the resulting menu, select Edit.

  6. In the dialog box under Quality of Service, select a new QoS policy or custom settings to apply to the volume.

  7. If you chose custom settings, modify the Min IOPS, Max IOPS, and Burst IOPS values.

    Note You can also click Reset Default QoS to restore default IOPS values.

  8. Click OK.

Edit a QoS policy

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

Steps

  1. From the vCenter Plug-in, open the Management tab:

    • Beginning with Element vCenter plug-in 5.0, select NetApp Element Remote Plugin > Management > Management.

    • For Element vCenter plug-in 4.10 and earlier, select NetApp Element Management > Management.

    Note If two or more clusters are added, ensure that the cluster you intend to use for the task is selected in the navigation bar.

  2. Click the QoS Policies sub-tab.

  3. Select the check box for the QoS policy you want to edit.

  4. Click Actions.

  5. In the resulting menu, select Edit.

  6. In the Edit QoS Policy dialog box, modify the following properties as needed:

    • Policy Name: The user-defined name for the QoS policy.

    • Min IOPS: The minimum number of IOPS guaranteed for the volume.

    • Max IOPS: The maximum number of IOPS allowed for the volume.

    • Burst IOPS: The maximum number of IOPS allowed over a short period of time for the volume. Default = 15,000.

      Note You can also click Reset Default QoS to restore default IOPS values.

  7. Click OK.

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 values previously defined by the policy but as individual volume QoS. Any association with the deleted QoS policy is removed.

Steps

  1. From the vCenter Plug-in, open the Management tab:

    • Beginning with Element vCenter plug-in 5.0, select NetApp Element Remote Plugin > Management > Management.

    • For Element vCenter plug-in 4.10 and earlier, select NetApp Element Management > Management.

    Note If two or more clusters are added, ensure that the cluster you intend to use for the task is selected in the navigation bar.

  2. Click the QoS Policies sub-tab.

  3. Select the check box for the QoS policy you want to delete.

  4. Click Actions.

  5. In the resulting menu, select Delete.

  6. Confirm the action.
