A while back, you may have seen my post for my 10/40GBe Network Upgrade. However, you were likely disappointed like myself, due to the lack of any actual 40GBe test results.
Well, today, I have managed to get 40Gbit point to point connectivity from my PC, to my Server, and I have prepared test results!
Wait, the R720XD doesn’t support bifurcation?
And- you would be correct by saying that.
However- There are special PCIe cards you can acquire, which will perform the bifurcation.
Credit for this idea goes to THIS POST which was brought to my attention by a fellow redditor. (I couldn’t find the comment from a month ago..)
As a note- this isn't specific to the R720XD, this guide/hardware should work in any hardware with the proper PCIe slots, which does not support bifurcation out of the box.
