I've been hoovering the buy button a few times lately wondering "I can haz two 10 gigabit cards and a cable for $50? should I just do it already?" Only minor draw-back I see is that the cards require that you use a x8 slot for them. Apart from that minor detail.. seems like a steal?
On Windows I'm using the Mellanox 5.50 driver (it does not officially support ConnectX-2, but works better than the older one dedicated for X-2 in my tests). Firmware flashing and modification (disabling PXE for example) work well both under Linux and Windows.
With MTU set to 9600 iperf3 in either direction shows 9.81GBit/s while iperf --dualtest achieves 9.19GBit/s and 9.34GBit/s simultaneously. hrping shows around 0.5ms.
They do get warm, but even the latest 10Gbit models still have heat sinks. Not sure what more you're interested in knowing

Damn, that's too bad. I hoped Mellanox can stay independent. Or at least operational. Now I'm not so sure what NVidia decides to do with them.
Infiniband is an interesting and powerful technology. I hope it stays around.

...now i got the point. Nvidia wants to improve their raytracing technique thats why the have acquiered a company which produces fiberoptics connections ..those clever bastards

You segregate it with networking (managed switches) and lock down any access with firewalls.
The firmware isn't the problem here as its isolated where it can't read from the system unless allowed.
IOMMU should protect against that but again, it's a black box protecting you from another black box, that apparently isn't as solid as I thought, given the reports I saw.
The concern is the driver stack becoming closed; no way to stop data exfiltration if that happens.
The issue is more on the desktop side.

I don't think this is happening.

Welp. That was a sudden shock. Guess our newer deployments will start looking at <n>00gig Ethernet instead of Infiniband. Fully expect NVIDIA to close this down and put data slurp in their new EULA, plus signed firmware and a special "enterprise" license you have to pay annually for.
RIP Infiniband. Your were a trusted companion on our HPC journey for so many years.
