View and manage quotas

View and manage quotas

To prevent system capacities from being exhausted without notification, you can set up quotas. Quotas are operational limits. For example, the number of gigabytes allowed for each project can be controlled so that cloud resources are optimized. Quotas can be enforced at both the project and the project-user level.

Typically, you change quotas when a project needs more than ten volumes or 1 TB on a compute node.

Using the Dashboard, you can view default Compute and Block Storage quotas for new projects, as well as update quotas for existing projects.

Note

Using the command-line interface, you can manage quotas for the OpenStack Compute service, the OpenStack Block Storage service, and the OpenStack Networking service (For CLI details, see OpenStackClient CLI reference). Additionally, you can update Compute service quotas for project users.

The following table describes the Compute and Block Storage service quotas:

View default project quotas

  1. Log in to the dashboard and select the admin project from the drop-down list.

  2. On the Admin tab, open the System tab and click the Defaults category.

  3. The default quota values are displayed.

Note

You can sort the table by clicking on either the Quota Name or Limit column headers.

Update project quotas

  1. Log in to the dashboard and select the admin project from the drop-down list.

  2. On the Admin tab, open the System tab and click the Defaults category.

  3. Click the Update Defaults button.

  4. In the Update Default Quotas window, you can edit the default quota values.

  5. Click the Update Defaults button.
