Hi Folks,
Did anyone experienced some performance limitations in Labs with the virtual switch function as the bottleneck when dealing with network overlays? I mean with the tunnel end point located on the hypervisor (virtual switch), setting up Tagging, QoS, ACL, encryption/decryption, etc. require significant CPUs. I know there is not yet official nvo3 implementation there, though VSphere 5 announced it with VXLAN recently but at any chance if some studies have been done, I would be glad to read those. I know STT has been built to overcome such challenges thanks to the NIC offload capabilities… These studies may also drive the brainstorming about which protocol we may use/build? Thank you! david le goff.
