Server racks in data centers deliver features and scale related to critical applications such as network virtualization, security, load balancing and telemetry. The number or VMs that can be deployed per server in the rack relates to available CPU resources and networking bandwidth. The Netronome® Agilio® solution used in compute node servers improves both metrics, and significantly reduce CAPEX and power consumption per rack, while boosting output performance and scalability per rack.
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). 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).
