I recently got into the position of having to reconfigure a network

Why would this not be the expected behavior? Are you autistic?

Because i was convinced that the number of ports is first and foremost for reasons of multiple connections and fail safety and the NIC itself, not each individual port will be able to supply the 1000/10000 bandwidth
For example similar to how GPUs have different video output ports being supplied by the same central unit

Multiple ports on those NICs are also supplied by the same chip.

But just like you can have fully independent outputs on your GPU showing different pictures, you can have fully independent Ethernet ports here.

You can be limited by PCIe bandwidth though, as PCIe 3.0 x4 is barely enough for 2x10G connections.

>2x10G
>4x1G


Anyway, these cards are fine. The only drawback they have is that they're on the same IOMMU group, so if you want to virtualize your servers, you will have to pass through the entire card.

Wait, I'm lost. I've never run across the behavior described by the OP. How or when did this odd way of thinking come about? I don't recall seeing this problem even in the 90's.

Bus bandwidth like >>59653107 states. I remember doing pairing or bonding with ISA and PCI cards even in the 90's since it was cheaper than these multiple port cards. Virtualization has also been a thing for ages.

How did you even get into networking?

Regular PCI is indeed not enough for more than one GbE interface. But that's why old servers had PCI-X.

Speaking of multi-port cards, can I use one of these with Win7 (not Server) or does it have some stupid limitations?

>>59653318
True but it also wasn't that long ago I was running rg6 before 10base T for networks.

>>59652745
Each port supports its own bandwidth but the switch/router backplane may not support the full bandwith of all switch modules installed. That's really all you need to know.

Those chips right next to the port can each handle 1Gbit.
If it was only 1 chip you would be right though.
