  <title>View and manage quotas</title>
  <para>As an administrative user, you can set quotas when you <xref
      linkend="dashboard_create_project"/> or update quotas for an
    existing project. Quotas are operational limits that prevent
    system capacities from being exhausted without notification. For
    example, to optimize cloud resources, you can control the number
    of gigabytes allowed for each project. You enforce quotas at the
    project, or tenant, level rather than at the user level.</para>
  <para>Typically, you change quotas when a project needs more than 10
    volumes or 1 TB on a Compute node.</para>
  <para>The following tables describe the Compute and Block Storage
    service quotas:</para>
