Ddante4 replied to the thread 7050QX-32S DCB (Lossless ethernet).You misunderstood me, I mean that 25GbE will require new switch and 25G switches are costly AF. And you can't downgrade 40G to 25G since...

Ddante4 replied to the thread 7050QX-32S DCB (Lossless ethernet).To be fair. What other purpose may be behind using cheap piece of hardware to get cool results? While you are correct regarding 50GB...

Ddante4 replied to the thread 7050QX-32S DCB (Lossless ethernet).Indeed, you are correct. Missed that CX4 didn't had 4.0. Erm. And? Which point of mine it counters? x1 pcie 3.0 line is 985 MB/s...

Ddante4 replied to the thread 7050QX-32S DCB (Lossless ethernet).If I would have platinum ESXi partner that would be solution indeed. But in such case there would be no need to use ConnectX-3 cards in...

Ddante4 replied to the thread 7050QX-32S DCB (Lossless ethernet).Not really DCBx is costing like this. 100G and 40G connectX-4 is the same cost, since well, they ARE the same card.
