What I am miss?

Hi,

Mellanox has drivers in sys/dev/mlx5 for CX-4 which support 100GBit/s
speeds.

can you some clarification?
what relation between cx-4 and ConnectX®-4 Lx EN?

Hi,

The LX series has lower throughput and is cheaper. You'll need the regular CX-4 if you want to do 100GBit/s. Meny, correct me if I'm wrong.

Is the same?

PS: 100G transmiters and connectiveti too expensive, 2x40G prefer.

You can put 2x 40GBit/s modules in the CX-4. I'm not sure if you can combine 2x 40GBit/s into a single 80GBit/s.
