The following figure identifies the required physical configuration of two servers equipped with supported network adapters connected back-to-back.
Figure 1. Test setup

- Two servers are equipped with supported network adapters and connected with a single cable between the supported interfaces.
- The supported interfaces are configured with an IP address so that traffic can pass between them. Use
pingto verify connection. - Onload, TCPDirect, and sfnettest are installed on both machines.
If required, tests can be repeated with a switch on the link to measure the additional latency delta using a particular switch.
