Chapter 2. Requirements

This chapter outlines the main requirements for setting up an environment to provision Red Hat OpenStack Platform using the director. This includes the requirements for setting up the director, accessing it, and the hardware requirements for hosts that the director provisions for OpenStack services.

Note

Prior to deploying Red Hat OpenStack Platform, it is important to consider the characteristics of the available deployment methods. For more information, refer to the recommended best practices for installing Red Hat OpenStack Platform.

2.1. Environment Requirements

Minimum Requirements

  • 1 host machine for the Red Hat OpenStack Platform director
  • 1 host machine for a Red Hat OpenStack Platform Compute node
  • 1 host machine for a Red Hat OpenStack Platform Controller node

Recommended Requirements

  • 1 host machine for the Red Hat OpenStack Platform director
  • 3 host machines for Red Hat OpenStack Platform Compute nodes
  • 3 host machines for Red Hat OpenStack Platform Controller nodes in a cluster
  • 3 host machines for Red Hat Ceph Storage nodes in a cluster
Note the following:
  • It is recommended to use bare metal systems for all nodes. At minimum, the Compute nodes require bare metal systems.
  • All Overcloud bare metal systems require an Intelligent Platform Management Interface (IPMI). This is because the director controls the power management.
