I want to link two unraid servers using SFP+

Just like the title says I would like to use a DAC cable and connect two unraid servers together to transfer files between them faster. I understand I wont be able to saturate that link withouth NVME drives but I would still like to try and accomplish this. Is this even possible? If so what do I need to do to connect them? I've seen spaceinvaders video on connecting an unraid server to a windows pc but thats not possible atm(location).

Two SFP+ NICs (e.g. Mellanox ConnectX-2/3 and a cable.

Okay so I have this care to explain how to properly link them together within unraid? I put each into bridge mode and gave them static IP's. Is there anything else that I am missing? What would be the best way to share content between them? Thank you.

I don't use bridge, just have a different IP range for the 10GbE NICs and then connect using those IP addresses, can also still connect by gigabit if needed using the gigabit IP.

Gotcha, I had most everything set then just bridge = yes was incorrect. I changed that and things are working great thank you. One question what do you use to transfer files between servers? Thanks for the help.

Mostly btrfs send/receive and some rsync, both over SSH witch in itself is not great for speed, but still much better than gigabit.
