Appendix G. Red Hat OpenStack Platform for POWER
For a fresh Red Hat OpenStack Platform installation, overcloud Compute nodes can now be deployed on POWER (ppc64le) hardware. For the Compute node cluster, you can choose to use the same architecture, or have a mix of x86_64 and ppc64le systems. The undercloud, Controller nodes, Ceph Storage nodes, and all other systems are only supported on x86_64 hardware. The installation details for each system are covered in previous sections within this guide.
G.1. Ceph Storage
When configuring access to external Ceph in a multi-architecture cloud, set the CephAnsiblePlaybook
parameter to /usr/share/ceph-ansible/site.yml.sample
along with your client key and other Ceph-specific parameters.
For example:
parameter_defaults: CephAnsiblePlaybook: /usr/share/ceph-ansible/site.yml.sample CephClientKey: AQDLOh1VgEp6FRAAFzT7Zw+Y9V6JJExQAsRnRQ== CephClusterFSID: 4b5c8c0a-ff60-454b-a1b4-9747aa737d19 CephExternalMonHost: 172.16.1.7, 172.16.1.8
G.2. Composable Services
The following services typically part of the controller node are available for use in custom roles as Technology Preview, and therefore, not fully supported by Red Hat:
-
Cinder
-
Glance
-
Keystone
-
Neutron
-
Swift
For more details please see the documentation for composable services and custom roles for more information. Below would be one way to move the listed services from the Controller node to a dedicated ppc64le node:
