[openstack][neutron] OpenStack deployment

Hi,

I planning to deploy OpenStack for production zed release, OVS with DVR when I went through the reference architectures I can see

- 3 controller, 3 network and x compute nodes or - 3 controllers + network and x computes nodes

I want to understand what happens if I go with the below configuration OVS with DVR

- 3 controller node - x compute + network nodes

For example I have 13 nodes, 3 controllers, 10 compute + network nodes what is the advantage/disadvantage for this configuration

Thanks & Regards, Dhana
