<title>View and manage quotas</title>
|
|
<para>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 tenant can be controlled so that
|
|
cloud resources are optimized. Quotas can be enforced at both the tenant
|
|
(or project) and the tenant-user level.</para>
|
|
<para>Typically, you change quotas when a project needs more than ten
|
|
volumes or 1 TB on a compute node.</para>
|
|
<para>Using the Dashboard, you can view default Compute and Block Storage
|
|
quotas for new tenants, as well as update quotas for existing tenants.</para>
|
|
<note>
|
|
<para>Using the command-line interface, you can manage quotas for the
|
|
OpenStack Compute service, the OpenStack Block Storage service, and
|
|
the OpenStack Networking service (see <xref linkend="cli_set_quotas"/>).
|
|
Additionally, you can update Compute service quotas for
|
|
tenant users.</para>
|
|
</note>

<para>The following table describes the Compute and Block Storage
|
|
service quotas:</para>
