We used two 2-socket PowerEdge servers as the two-node RAC servers, with each running Oracle Linux 7.8. Each RAC node had two dedicated 25 GbE network ports (Linux-network-bonded) for the Oracle public traffic, two dedicated 25 GbE network ports for the two Oracle private interconnect networks and two dedicated 25 GbE network ports (Linux-network-bonded) for the shared-storage data traffic. Each database server had 768 GB of physical memory and two Intel Xeon Scalable 18 core processors. We installed a two-node Oracle Grid Infrastructure 19c and RAC database on these two servers.
