  • 1.  NSX-T Load testing Edge Transport Nodes (VMs)

    Posted Jan 05, 2021 12:11 PM

    I am nearing completion of setup of NSX-T 3.1 and would like to do some final testing on throughput / resilience of the Edge Transport Nodes under load.

    I would like to understand the maximum throughput of the Edge VMs in terms of MB/s throughput, Max Concurrent Connections and Max New Connections/Second. The main reason for this is to see how it will perform in a case of DOS-type attacks or increased overall load in peaks.

    Does anyone have any experience/suggestions?

    Any help appreciated. Thanks!

    there is not like a rule on this since all the deployments are different NICs are different,  servers are different, an internal bus is different, Processor is different, so what I can say is try to test by yourself to get a real approximation to the benchmark that u are looking, so for example by the nature of the EDGE VM factor is 10GB/sec max but is not always saturated 8-9GB depending on traffic, so that is why you should test by your env., also another approximation could be to take the number of NSXV ESG so for this is 1M cps, so for EDGE VM in case of NSXT you get lots of improvements in datapath so I infer that numbers could be bigger.


    hope this helps to approximate to an answer for the baseline fits you.

    Edge VM is not limited to 10 Gbps, it can deliver over 20 Gbps throughput.
