no, at the moment it does not. But as far as I know our group is one of several interested users, and I've just come home from OpenStack Summit in Tokyo where this was a hot topic for us. In short, we are researching a design where SR-IOV "VLAN channels" are used as Neutron subports - in our use case, this would be done by running a Felix daemon in the control pane of our Cumulus-based L3 switches. The idea is to then route all traffic using the hardware router on the switch. Calico or Felix does not support this configuration yet but as far as we can see the model supports it well, and implementing it should be possible even with limited resources. If you don't have the option of running Felix on the switch control pane it becomes a larger task, but still doable. A refactor of the Felix daemon into separated services would make this easier. A solution that uses SR-IOV to connect instances to a routed fabric seems like it will enable more latency-bound workloads for us. We got quite some interest from internal research/science projects on this. Really interested in any more information you could provide about your use case. best regards, Jan Ivar Beddari, UH IaaS (Norwegian academic community cloud) _______________________________________________ calico-tech mailing list calico-tech@lists.projectcalico.org http://lists.projectcalico.org/mailman/listinfo/calico-tech_lists.projectcalico.org
