{rh-openstack-first} deployments do not have a single implementation of failure domains. Instead, availability zones are defined individually for each service, such as the compute service, Nova; the networking service, Neutron; and the storage service, Cinder.
1116
-
1117
-
Beginning with {product-title} 4.13, there is a unified definition of failure domains for {rh-openstack} deployments that covers all supported availability zone types. You can use failure domains to control related aspects of Nova, Neutron, and Cinder configurations from a single place.

In {rh-openstack}, a port describes a network connection and maps to an interface inside a compute machine. A port also:
1120
-
1121
-
* Is defined by a network or by one more or subnets
1122
-
* Connects a machine to one or more subnets
1123
-
1124
-
Failure domains group the services of your deployment by using ports. If you use failure domains, each machine connects to:
1125
-
1126
-
* The `portTarget` object with the ID `control-plane` while that object exists.
1127
-
* All non-control-plane `portTarget` objects within its own failure domain.
1128
-
* All networks in the machine pool's `additionalNetworkIDs` list.
1129
-
1130
-
To configure failure domains for a machine pool, edit availability zone and port target parameters under `controlPlane.platform.openstack.failureDomains`.
|The ID of an individual port target. To select that port target as the first network for machines, set the value of this parameter to `control-plane`. If this parameter has a different value, it is ignored.
|Subnets to allocate fixed IP addresses to. These subnets must exist within the same network as the port.
1173
-
|A list of `subnet` objects.

NOTE: You cannot combine zone fields and failure domains. If you want to use failure domains, the `controlPlane.zone` and `controlPlane.rootVolume.zone` fields must be left unset.
