Yes, OpenStack definitely supports a multi-node deployment.  OpenStack has 
a lot of flexibility in what you deploy and how.  Which services you run 
on which node depends on what services you deploy in your system and what 
you want to do about high availability for the logical singletons.  You 
can start to get some clues in 
http://docs.openstack.org/havana/install-guide/install/apt/content/ch_overview.html 
--- but that does not attempt to be comprehensive.  For example, it does 
not show deployment of Cinder in the later pictures; Cinder is discussed 
in 
http://docs.openstack.org/havana/install-guide/install/apt/content/ch_cinder.html

Mike
