Chapter 2. Requirements

This chapter outlines the main requirements for setting up an environment to provision Red Hat Enterprise Linux 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.

2.1. Environment Requirements

Minimum Requirements

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

Recommended Requirements

  • 1 host machine for the Red Hat Enterprise Linux OpenStack Platform director
  • 3 host machines for Red Hat Enterprise Linux OpenStack Platform Compute nodes
  • 3 host machines for Red Hat Enterprise Linux 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.
