Hi All,
can you share what kind of old NICs do you use on CentOS 8 (Stream or not , it doesn't matter) without any issues? I was looking at ebay and I found some pretty old Mellanox "ConnectX" or "ConnectX-2" but I seriously doubt they will work on CentOS 8.
Any proposals are also welcome. I don't care of the brand as long as it is PCIe and is supported by the vanilla kernel.
Best Regards, Strahil Nikolov

I'm using a number of HP branded MT27520 Family [ConnectX-3 Pro] InfiniBand FDR/Ethernet 10Gb/40Gb 2-port 544+FLR-QSFP Adapters without any issue. Not sure if that is old enough for you.

They work, had a NAS running SMB and NFS serving to a couple ESX for backups using a dual port Connect-X.
The ones that have their issues are mostly the VPI/IB models which need to be reflashed to the ethernet firmware, on servethehome's forums there's plenty info about this.

I believe connectx2 work using the plus kernel, however look for a connectx 3 or 4 either native Ethernet (EN) or a VPI variant, these will be 40Gb and you can use a qsfp to sfp+ convertor, or 40Gb transceiver (auto negotiated to 10Gb).
You can change the port profile using mellanox tools or editing the profile in /says.
