Hi,
You can't have two cluster on one phy node, but: 1. You may have one Pacemaker cluster and run all your apps as independent resources. 2. You may setup Proxmox VE on your two nodes, create 4 VMs and setup two clusters, one per your app. Extra virtualization layer will eat some resources, not so much, but provide you with better flexibility in every aspect. Also, one important note: consider the third node for arbiter. Two-node-cluster is always very, very bad idea. You may use a very small node for arbiter, but it is much better to have it. BTW, the same about 4 baremetal, it is much better then 2 bit in this case fifth arbiter node is a good idea.

I ask because for a SAP HA setup with pacemaker SAP/RHEL recommend a separate cluster for the application and server part. i.e SAP itself in one cluster and Hana and the other. We are trying to have only two baremetal servers in one site rather than four.
