Quotas set to a value of -1 are disabled, meaning they are ignored.

Not all of the above quotas are of importance to all customers. Those quotas highlighted in the above list, are the ones that are relevant for most customers. Here is an explanation of what they mean:

cores

The total number of cores assigned to all VMs of the project. This includes cores assigned to shelved VMs.

instances

The total number of VMs in the given project. This includes shelved VMs. This does not include VMs that are part of load balancers created through the OpenStack Octavia LBaaS service.

ram

The total amount of RAM (in GiB) assigned to all VMs of the project. This includes RAM assigned to shelved VMs.

networks

The number of networks created in the project.

volumes

The total number of volumes (virtual disks) in the project. This includes volumes attached to shelved VMs as well as volumes that are not currently attached to any VM at all.

gigabytes

The total size of all volumes in the project.

ports

The total number of ports or network interfaces in a project. This includes the ports on OpenStack routers, as well as the DHCP/DNS instances which are part of every newly created network.

routers

The number of OpenStack routers in the project.

subnets

The number of subnets in the project. By default, each network has one subnet, but it is possible to create a network that contains several subnets.

floating-ips

The number of public IPv4 addresses assigned to the project. This includes IPv4 addresses that are assigned to the project but not currently assigned to any VM.

secgroups

The number of security groups in the project.

secgroup-rules

The number of security group rules accross all security groups in the project.

per-volume-gigabytes

The maximum size any single volume can be.
