How to setup multiple Neutron servers managed by a single controller?
All multi-node architecture information I could find was talking about: single machine for controller, single machine for neutron, single\multiple machine for Nova.
There is a basic thing I cant understand. this means that if I have for example 3 compute servers running Nova on each one - all data traffic of the VMs on those 3 servers, must pass first via the same neutron server. Am I right?
This doesnt make sense from scale point of view... Can I have architecture on which I have for example, 1 controller, managing 6 Nova servers, and 2 Neutron servers (one neutron per 3 Nova servers traffic)? In other words, can I have multiple neutron servers in the same setup managed by a single controller?
