- * **Node 1**: This node has MongoDB and Controller roles. The controller
- node runs the Identity service, Image Service, management portions of
- Compute and Networking, Networking plug-in and the dashboard. The
- Telemetry service which was designed to support billing systems for
- OpenStack cloud resources uses a NoSQL database to store information.
- The database typically runs on the controller node.
-
- * **Node 2**: This node has Controller and Ceph-osd roles. Ceph is a
- massively scalable, open source, distributed storage system. It is
- comprised of an object store, block store and a POSIX-compliant distributed
- file system. Enabling Ceph, configures Nova to store ephemeral volumes in
- RBD, configures Glance to use the Ceph RBD backend to store images,
- configures Cinder to store volumes in Ceph RBD images and configures the
- default number of object replicas in Ceph.
-
- * **Node 3**: This node has Controller role in order to achieve high
- availability.
-
- * **Node 4**: This node has Compute role. The compute node runs the
- hypervisor portion of Compute that operates tenant virtual machines
- or instances. By default, Compute uses KVM as the hypervisor.
-
- * **Node 5**: This node has compute role.
