Cross-plane interference verification is critical to proper operation and
planning and would be great to add to OVP.
I am planning to discuss about this kind of test with the Bottleneck team at
the plugfest since that is what Bottleneck should be able to support.
As for which data plane tool is best suited for this task, given this is a full
system stack, NFVbench is more appropriate since VSPERF is more applicable for
isolated vswitch level performance benchmarking – in general you cannot and
should run VSPERF on a full stack since the vswitch would be under the full
control of the stack controller (Neutron ML2 plugin or any SDN controller).
The main impediment to running any data plane benchmarking is the hardware
requirements, which is something I can discuss with Georg at the plugfest. It
will require the OVP system under test to expose certain interfaces to an
external traffic generator, not a big deal but often misunderstood.
Thanks

Hi Mark,
I very much like the idea because this methodology allows us to evaluate a
specific performance characteristic (“no performace interference between
storage and network data”) without having to report concrete performance
numbers as part of OVP.
The next Dovetail call is tomorrow, and we can add this to the agenda. If you
cannot make it on such short notice, we’ll move it to next week. Feedback via
email from the team and the performance benchmarking community is welcome any
time.
Best regards
Georg

Had a brief conversation with Georg about setting a bar for entering into the
performance phase of Dovetail:
The concept is to run a tenant network workload (Vsperf or NFVBench) and
capture the baseline. Next run a storage network workload (StorPerf) and
capture its baseline. Next run both together and if there is a significant drop
in either (ie don’t record the actual throughputs, just the delta) report that
as non compliant because storage and tenant networks are colliding.
Perhaps we can discuss this concept in an upcoming meeting?
Regards,
Mark
