OpenStack quotas
Most of the OpenStack resources you create in Cleura Cloud are subject to quotas. Once you hit a quota limit, the creation of new resources of that type will fail, until you either reduce your resource utilization or your quota is raised.
Cleura Cloud applies most quotas on a per-project basis. Your Cleura Cloud account can manage up to 3 projects.
The following quotas apply in any of your Cleura Cloud projects by default:
| Quota name | Value | Notes |
|---|---|---|
cores |
20 | Maximum number of virtual CPU cores allocatable across all servers (“instances”). |
floating_ips |
50 | Maximum number of public (“floating”) IPv4 addresses allocated in your project. The limit on floating IP addresses applies regardless of how many are “in use” (that is, associated with a port) at any given time. |
gigabytes |
1000 | Maximum total amount of persistent storage used by all volumes (in GiB). |
instances |
10 | Maximum number of servers in your project. This limit applies irrespective of whether the server is running, suspended, or shut down. |
networks |
100 | Maximum number of networks. |
ports |
500 | Maximum total number of ports (virtual network interfaces) across all servers, routers, and load balancers. |
ram |
51200 | Maximum total amount of RAM used by all servers (in MiB). |
rbac_policies |
10 | Maximum number of Role-Based Access Control (RBAC) rules defined for your networks. (Rarely used.) |
routers |
10 | Maximum number of virtual routers. |
secgroup_rules |
100 | Maximum number of security group rules (across all security groups). |
secgroups |
10 | Maximum number of security groups. |
server_group_members |
10 | Maximum number of servers allocated to one server group. |
server_groups |
10 | Maximum number of server groups. |
snapshots |
10 | Maximum number of volume snapshots. |
subnets |
100 | Maximum number of subnets. Note that subnets are either for IPv4 or IPv6, so in a dual-stack environment every network corresponds to two subnets. |
volumes |
50 | Maximum total number of persistent volumes. |
There is one other quota that applies per OpenStack API user, not per project:
| Quota name | Value | Notes |
|---|---|---|
key_pairs |
100 | Maximum number of secure shell key pairs. |
Reviewing your quota
Using the openstack CLI, you can always review the applicable quota settings for your project with the following command:
openstack quota show
Requesting a quota increase
If you find that you need to deploy more resources in one project than the default quota allows, or if you need to manage more than 3 projects in your account, please file a support request with our Service Center.
