|
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.
|
|
|
|
Typically, you change quotas when a project needs more than ten
|
|
volumes or 1 |nbsp| TB on a compute node.
|
|
|
|
Using the Dashboard, you can view default Compute and Block Storage
|
|
quotas for new tenants, as well as update quotas for existing tenants.
|
|
|
|
.. 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 (see `OpenStack Administrator Guide
|
|
<http://docs.openstack.org/admin-guide/cli_set_quotas.html>`_).
|
|
Additionally, you can update Compute service quotas for
|
|
tenant users.
|
|
|
|
The following table describes the Compute and Block Storage service quotas:
