Hi all, OVS is a software solution switch as i understand. It is able to utilize offloading features of the Ethernet adapter I read somewhere...
- What features are those? Is it desirable to invest in 10GB adapters with full TCP chimney support like Emulex (OCe11102) or Broadcom (57810S) ? Or is Intel intelligent offloading the same for OVS? - Is OVS using virtual function available on the adapter (now or in the future)? e.g. Intel x540 adaters support 64 VF's per port. Around the same for Emulex and Broadcom. But Solarflare (SFN5121T) supports 254 VF's. Will that have an effect on OVM? - For best performance and minimal CPU overhead is there something else (not mentioned above) I should look into when comparing 10GB nics? - If i use OVS on a compute node with KVM as hypervisor, what will decide the maximum number of virtual nic's supported? e.g. My goal is to have max 100 vps with each max 4 vnics = max 400 vnics on 1 10GB port/adapter... which is why i want the best adapter for this purpose...with maximum offloading of OVS. Thank you very much and keep up the great work! Atam
