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:
