Current FD.io production testbeds are built with SUT servers based on
the following processor architectures:
-- Intel Xeon: Skylake Platinum 8180, Haswell-SP E5-2699v3,
- Cascade Lake Platinum 8280, Cascade Lake 6252N.
+- Intel Xeon: Skylake Platinum 8180, Cascadelake 6252N, (Icelake 8358
+ installation in progress).
- Intel Atom: Denverton C3858.
- Arm: TaiShan 2280, hip07-d05.
- AMD EPYC: Zen2 7532.
+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.
All AMD EPYC Zen2 7532 servers run with AMD SMT enabled, doubling the
number of logical cores exposed to Linux.

+
+One 2n-icx testbed located in Intel labs was used for CSIT testing. It
+is built with two SuperMicro SYS-740GP-TNRT servers. SUT is equipped
+with two Intel Xeon Gold 6338N processors (48 MB Cache, 2.20 GHz, 32
+cores). TG is equiped with two Intel Xeon Ice Lake Platinum 8360Y
+processors (54 MB Cache, 2.40 GHz, 36 cores). 2n-icx physical topology
+is shown below.
