The XC Family cluster for SAP HANA consists of dual-socket XC740xd nodes or quad-socket XC940 nodes. Dell Technologies recommends a minimum of four nodes. Mixing two-socket and four-socket nodes is allowed within a cluster. This approach provides flexibility because you can start small and scale up or out based on your requirements.
The configuration that is shown in the following figure represents one of the XC Family cluster configurations that is supported for SAP HANA deployments. The cluster architecture consists of a mix of dual-socket nodes and quad-socket nodes. In this example, one XC940 node and two XC740xd nodes are active nodes, with one SAP HANA production system per socket. The XC940 node hosted three production SAP HANA VMs and the XC740xd node hosted one production SAP HANA VM. The fourth node (XC940) is a stand-by node for HA. This stand-by node must have equivalent compute resources available to accommodate the SAP HANA VMs during node failure scenarios.
Note: Dell Technologies representatives are available to assist with sizing and designing the cluster configuration based on customer requirements.
