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. <br>
<br>
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....<br>

<div class="moz-cite-prefix">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 !<br>
<br>
I have been struggling to find a solution out of it, can you
suggest some please ?<br>

<div>The Quantum Admin Guide indicates that you can choose to
combine all services onto a single node, or have separate
nodes: <a moz-do-not-send="true"

<div><br>
</div>
<div>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.</div>

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

<div>Hi Openers,</div>
<div> </div>
<div>One doubt i have is like, as we see in the
demo setup in the Quantum Admin guide available
in <a moz-do-not-send="true"
href="http://openstack.org" target="_blank">openstack.org</a>,
we have Network Node as a seperate physical node
connected to Controller Node and Compute Node.</div>
<div> </div>
<div>But i see that the openstack community who is
actively using Folsom is not discussing more on
this kind of setup.</div>
<div> </div>
<div>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.</div>
<div> </div>
<div>Open comments on this will be more helpful
for openstack community to understand better on
the features of folsom.</div>
