Hello Ophir,
Thank you for your helpful answer.
The maximum simultaneous rate (TX/RX) that we achieved by your recommendation based on Mellanox performance is 64 Gbps (dual port).
1. We have a Dell 720xd server with PCIe *16 (4slot PCIe*8 and 2 slot PCIe*16), it means that we can achieve 128 Gbps. How ever Mellanox card are *8 lanes means 8*8=64 Gbps. Is my conclusion true?
2. Why if i use 2 Mellanox card in the first server and 2 Mellanox card on the second server and connect actively four cards (2 connections: one TX and One RX) I am still stuck at 64 Gbps!?
Thanks!
