I was wondering if I used something like this on a pcie v4 if I would actually get 10 G out of both ports at the same time? What do I need to look for?
The PCIe is not likely the limitation. Remember pcie numbers are in MBYTE.
It is very complex to use 2 ports at those speeds. Largest issue is getting a disk/file system can run that fast. You also have limits on using 2 ports on the same OS.
What width PCIe V4 slot ? X1, x4, or x8 ?I was wondering if I used something like this on a pcie v4 if I would actually get 10 G out of both ports at the same time? What do I need to look for?
I am just connecting one interface of my Linux router to the data center router and the other interface to my switch. I need 10G service because my 1G is up to 50% right now so I am planning for an upgrade. This is not for home use at all.There's several other home datacenter based forums. I'd check some other places. A lot of fiber stuff people buy used. I'm not sure the best ones to pick but there's a lot of options and nuance. 10G used and DAC cable compatible isn't too expensive from what I under stand. Also watch out for older stuff using a ton of power. If you don't really need 10G it's not really worth the hassle. the best option is often what data centers used the most and are replacing since it ends up being pretty cheap 2nd hand. most of it costs a fortune new.
Yes you would get 10G out of both ports at the same time in both directions. LACP is the standard bond mode that will be compatible with many switches. 1 connection is only on one nic. if you connect two linux machines together you can try other bond types that try and push packets across both nic. I don't think it's very common or popular to use. If you need more throughput than 10 for a single connection you should go for 40G or 100G.

If you look at the performance of V2 -- https://en.wikipedia.org/wiki/PCI_Express#History_and_revisions An x8 slot as this card was designed with has 4GB/s that is 32Gb /s so you could have 20Gb throughput. But you HAVE TO us an x8 slot.Keep in mind I am looking to have 10 G on each port since I am using it in a router, From what I am reading a PCIe 2 card would not give me the full 10 G on each port on one card x8 card. Even a PCIe 4 x card would only give me a total of 16 G. Would I not need to have 20 G to get 10 G on each port? Is that correct?
