The key inputs for calculating TCO for a rack include server and power costs, ToR switch power and costs, and expected output per VM. Assumptions for modeling TCO are vSwitch performance for non-accelerated and Agilio-accelerated OVS. The assumptions in the calculator are derived from rigorous testing done in labs (see Netronome’s OVS test plan
and related traffic generator test tools
). The calculator reveals savings based on the CAPEX and OPEX of an accelerated and non-accelerated rack configuration that drives on an expected application output, measured in Packets Per Second (PPS).
