The Red Hat OpenShift Container Platform 4.6 Reference Architecture design requires a minimum of four servers for a three-node cluster, with each node running as both a control-plane node and a compute node. If required, a three-node cluster can be expanded to a standard cluster. You can also expand the standard cluster with more compute nodes at any time. The maximum configuration that the customized Dell Technologies deployment tools support is 210 servers.
