Confirming the multinode setup
We can divide our physical setup into the following two categories:
OpenStack node role assignment: The number of nodes as well as the services that will be running into each one
OpenStack node provisioning: The way we will conduct the installation of each one from the bare metal level
By combining our multinode setup with a bare metal provisioning that configures the physical servers on a hardware level and a services categorization by using a group of nodes, we have an end-to-end approach that can quickly install a primary OpenStack private cloud in a wide range of hardware.
Assigning physical nodes
Depending on the number of physical machines that you would like to deploy, take into consideration the best practices and recommendations that were discussed in the previous chapters while building your first OpenStack production environment. In the current example, the following nodes need to be installed:
Three controller nodes
Three compute nodes
Three Ceph OSD...
