For our smaller clusters, we typically do a 3 node setup. Control 
services are typically mirrored across two of the nodes we deem 
"controller nodes", and compute services go on all three. The two 
service nodes have some size reserved on them to prevent overrunning the 
services.

In this scenario we run Neutron in an HA mode on the control nodes. 
Neutron typically will run routing and gateway services on one of those 
nodes, with the ability to fail over to the other one.

This setup works quite well for many of our clients.
