<font size=2 face="sans-serif">Are you looking at scaling the numbers
of tenants, Neutron routers, and tenant networks as you scale hosts and
guests? I think this is a plausible way to grow. The compartmentalizations
that comes with growing those things may make a difference in results.</font>

[neutron] Neutron scaling datapoints?</font>

<hr noshade>

<br>
<br><tt><font size=2>My team is working on experiments looking at how far
the Neutron server<br>
will scale, with increasing numbers of compute hosts and VMs. Does<br>
anyone have any datapoints on this that they can share? Or any clever<br>
hints?<br>
<br>
I'm already aware of the following ones:<br>

Icehouse<br>
118 compute hosts<br>
80 Neutron server processes (10 per core on each of 8 cores, on the<br>
controller node)<br>
27,000 VMs - but only after disabling all security/iptables<br>
<br>
</font></tt><a href="http://www.opencontrail.org/openstack-neutron-at-scale/"><tt><font size=2>http://www.opencontrail.org/openstack-neutron-at-scale/</font></tt></a><tt><font size=2><br>
1000 hosts<br>
5000 VMs<br>
3 Neutron servers (via a load balancer)<br>
But doesn't describe if any specific configuration is needed for this.<br>
(Other than using OpenContrail! :-))<br>
<br>
Many thanks!<br>
