   6 Environment Versioning
   7 ----------------------

   9 CSIT test environment versioning has been introduced to track
  10 modifications of the test environment.
  11
  12 Any benchmark anomalies (progressions, regressions) between releases of
  13 a DUT application (e.g. VPP, DPDK, TRex), are determined by testing it in the
  14 same test environment, to avoid test environment changes clouding the
  15 picture.
  16
  17 A mirror approach is introduced to determine benchmarking anomalies due
  18 to the test environment change. This is achieved by testing the same DUT
  19 application version between releases of CSIT test system. This works
  20 under the assumption that the behaviour of the DUT is deterministic
  21 under the test conditions.
  22
  23 CSIT test environment versioning scheme ensures integrity of all the
  24 test system components, including their HW revisions, compiled SW code
  25 versions and SW source code, within a specific CSIT version. Components
  26 included in the CSIT environment versioning include:
  27
  28 - **HW** Server hardware firmware and BIOS (motherboard, processsor,
  29   NIC(s), accelerator card(s)), tracked in CSIT branch in
  30   :file:`./docs/lab/<server_platform_name>_hw_bios_cfg.md`, e.g. `Xeon
  31   Skylake servers
  32   <https://git.fd.io/csit/tree/docs/lab/testbeds_sm_skx_hw_bios_cfg.md#n556>`_.
  33 - **Linux** Server Linux OS version and configuration, tracked in CSIT
  34   Reports in `SUT Settings
  35   <https://s3-docs.fd.io/csit/master/report/vpp_performance_tests/test_environment.html#sut-settings-linux>`_
  36   and `Pre-Test Server Calibration
  37   <https://s3-docs.fd.io/csit/master/report/vpp_performance_tests/test_environment.html#id21>`_.
  38 - **TRex** TRex Traffic Generator version, drivers and configuration
  39   tracked in `TG Settings
