 Following is the description of existing production testbeds.
 
+2-Node Xeon Cascadelake (2n-clx)
+--------------------------------
+
+Three 2n-clx testbeds are in operation in FD.io labs. Each 2n-clx testbed
+is built with two SuperMicro SYS-7049GP-TRT servers, SUTs are equipped with two
+Intel Xeon Gold 6252N processors (35.75 MB Cache, 2.30 GHz, 24 cores).
+TGs are equiped with Intel Xeon Cascadelake Platinum 8280 processors (38.5 MB
+Cache, 2.70 GHz, 28 cores). 2n-clx physical topology is shown below.
