I've just been told that Asrock have a supply problem getting Intel 10gbe chips and none of their boards are currently available. I was looking at the ASRock Rack EPYC3251D4I-2T (8 cores, 16 threads) for a TrueNAS server but that's obviously out now. So what else is available? I also need 6 SATA ports but can do that via a HBA. And IPMI, obviously. I'd like the ability to have 64 GB of ECC RAM. The use case is primarily NAS but also running VMs.
