Link-Virtualization™ Software with RPM Distribution of OpenStack (RDO)

RDO introduction

RDO is an OpenStack packaged by the open source community for users running Red Hat based Linux distributions, such as CentOS, Fedora and Red Hat Enterprise Linux. This configuration example describes how to deploy RDO using OpenStack on OpenStack (TripleO). TripleO is used mainly in installations for production environments.

For more information on the TripleO deployment architecture and process, refer to the documentation at: https://docs.openstack.org/project-deploy-guide/tripleo-docs/latest/features/network_isolation.html.

Director

Undercloud runs on a 'director' which requires a provisioning network and an IPMI network. The provisioning network is used for PXE boot of servers and deploying installation images. The IPMI network is used for communicating with the BMC of servers which provides remote management features including power management and server monitoring.

Undercloud can be deployed either in a bare-metal server or a virtual machine. The system requirements are similar for a bare-metal server or a virtual machine.

Controller

The controller node determines how to deploy guest instances on compute nodes. The controller node also manages the connection of guest instances to the external network.

Compute

The compute nodes (nova) run guest instances. They have access to the internal network and the provider network (tenant, DPDK).
