   To check whether a kernel is 64-bit, verify that the ouput of the following command is `x86_64`.
   
  
positive.code: TRex port 0 ( server VLAN1) <->  | DUT  | <-> TRex port 1 ( client-VLAN1)
  ----
  
  In this case, traffic on vlan0 is sent as before, while for traffic on vlan1, order is reversed (client traffic sent on port1 and server traffic on port0).
  TRex divids the flows evenly between the vlans. This results an equal amount of traffic on each port.

  | Memory | 2x4 banks for each CPU. Total of 32GB in 8 banks. 
  | RAID | No RAID.
  | Riser 1/2 | Both left and right should support x16 PCIe. Right (Riser1) should be from option A x16 and Left (Riser2) should be x16. Need to order both.
