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. Thanks, Mike From: Neil Jerram <Neil.Jerram at metaswitch.com> To: <openstack-dev at lists.openstack.org> Date: 04/08/2015 12:29 PM Subject: [openstack-dev] [neutron] Neutron scaling datapoints? My team is working on experiments looking at how far the Neutron server will scale, with increasing numbers of compute hosts and VMs. Does anyone have any datapoints on this that they can share? Or any clever hints? I'm already aware of the following ones: https://javacruft.wordpress.com/2014/06/18/168k-instances/ Icehouse 118 compute hosts 80 Neutron server processes (10 per core on each of 8 cores, on the controller node) 27,000 VMs - but only after disabling all security/iptables http://www.opencontrail.org/openstack-neutron-at-scale/ 1000 hosts 5000 VMs 3 Neutron servers (via a load balancer) But doesn't describe if any specific configuration is needed for this. (Other than using OpenContrail! :-)) Many thanks!
