The Ready Stack for Red Hat OpenShift Container Platform 4.3 design requires a minimum of seven servers, each comprising three worker nodes. The maximum configuration that the customized Dell Technologies deployment tools support is 210 servers.
This design guide uses a server-node base configuration for the PowerEdge R640 and PowerEdge R740xd server nodes that can be used in each node role. For worker nodes that require add-in devices such as GPUs, we strongly recommend PowerEdge R740xd servers. Appendix A shows the PowerEdge server baseline configurations that we used in the design. The following table shows the hardware configuration that is required to build the cluster design that we used for our validation:

*During installation, one node is used to create the bootstrap node that is needed to deploy the master nodes. The bootstrap node can be converted to a worker node afterwards.
