+CSIT-2106 report data for Intel Xeon Icelake testbeds comes from
+testbeds in Intel labs set up per CSIT specification and running CSIT
+code. Physical setup used is specified in 2n-icx and 3n-icx sections
+below. For details about tested VPP and CSIT versions
+see :ref:`vpp_performance_tests_release_notes`.

 Server SUT performance depends on server and processor type, hence
 results for testbeds based on different servers must be reported
 separately, and compared if appropriate.
