Red Hat validated the following hardware configuration for a bare-metal deployment of SAP Data Intelligence 3.1 on Dell EMC Ready Stack for Red Hat OpenShift Container Platform 4.6 and OpenShift Container Storage 4.6 for production environments. The validation was conducted in Dell Technologies labs.
The production-level bare-metal cluster is listed on the OpenShift Container Platform validation version matrix and is confirmed and supported by SAP.
Note: The validation by Red Hat enables bare-metal deployments for SAP Data Intelligence 3.1 with OpenShift Container Platform 4.6 and OpenShift Container Storage 4.6 on the Dell Ready Stack for any supported cluster size for SAP Data Intelligence. The validation is not limited to the cluster configuration shown in the following table.
This solution uses a server-node base configuration for the PowerEdge R640 and PowerEdge R740xd server nodes that can be used in each node role. For compute nodes that require add-in devices such as GPU accelerators we strongly recommend choosing PowerEdge R740xd servers. Appendix A shows the PowerEdge server baseline configurations that we used in the design.
