Dan,
I see your point about throughput and I/O, but if you have a multi-core
server, greater than say 4 cores, and thus likely you would have
multiple NICs, 2 or More, your assumptions fall apart about the cpu
usage and I/o. For example, using XEN or Qemu or in the older systems
where this concept originated - VMS OS (from Digital Equipment Corp. -
see Galaxy product and similar) you can assign affinity to CPUs or even
dedicate CPU's to tasks or VM's. In addition, using Cisco networking or
similar you can dedicated I/O paths, and within a system, you can even
dedicated a NIC Card or Port to a path. So the deployment of OpenStack
on one physical server or several should not even be a consideration
except to the installer and their budget; and whether or not High
Availability is a concern. What I think is important is the consistency
of the network design, I/O design for multiple VM's and the related load
and intended usage of the individual cores of a server. But the most
important consistency is having installation guides that work over and
over for installations on different hardware and OS's.
Myself, if I can get past my current nova and horizon issues, I will
then be in a position to contribute in this and many other areas....
Regards,
Robert

Thank you Dan for shedding light on this matter. However, there is
something concerns me and a lot of other people trying to deploy
OpenStack is that most Servers has 2 NICs which creates a problem
because your Demo is a great one but the necessary hardware is just
not always met !
I have been struggling to find a solution out of it, can you suggest
some please ?

Hi,
The Quantum Admin Guide indicates that you can choose to combine all
services onto a single node, or have separate nodes:
http://docs.openstack.org/trunk/openstack-network/admin/content/services.html
I will update the text to indicate that that the main reason to use a
dedicated network gateway node is if you plan on having VMs send
substantial amounts of traffic through that node, and thus would not
want that CPU usage to conflict with other openstack services running
on your controller node.

Can someone please enlighten us about the goods of having a
separated network node ?
I honestly work in production envirnoments (over 30 nodes) and i
really give computing resources more credit than networking ones !
Am i doing it the wrong way here ?

Hi Openers,
One doubt i have is like, as we see in the demo setup in the
Quantum Admin guide available in openstack.org
<http://openstack.org>, we have Network Node as a seperate
physical node connected to Controller Node and Compute Node.
But i see that the openstack community who is actively using
Folsom is not discussing more on this kind of setup.
Not sure if iam missing any key information on this like that
the Network Node setup may not be widely used in current
deployment scenarios or it is too early to use Network Node as a
seperate physical host for openstack.
Open comments on this will be more helpful for openstack
community to understand better on the features of folsom.
regards,
balaji

Hi Skible,
Can you please send me below configuration files of three
setups you have mentioned.
* ovs_quantum_plugin.ini (For controller and node)
* nova.conf (For controller and node)
Thanks in advance
Regards,
Veera.

Hello Stackers !
I am currently trying to create pictures of my
OpenStack deployment architecture as a part of my
OpenStack Folsom install guide
<https://github.com/mseknibilel/OpenStack-Folsom-Install-guide/blob/master/OpenStack_Folsom_Install_Guide_WebVersion.rst>
and i would like to ask a favorite.
Could you be kind and please take a look at these Pics
below and report back if there is a missing or wrong thing.
Thank you.
