I am going to pose an honest question and request honest feedback, without this turning into a flame war. My Intel 2nd Gen Scalable on an X11SPi-TF home server suffered an unexpected catastrophic fault (CATERR) this weekend. Main board displayed the BMC booting up, reset, turn on without display output, reset, rinse, repeat, recycle, etc. After about three hours, I was able to get it back online, thank God, so all ended well.
I began to ponder the possibility of replacing the processor, main board, or both. Thoughts of "you too can live the dream of 256MB L3 cache" danced through my head, but then some recent comments by everyone's favorite Canuck (don't judge, I watch for the drops and hardware on fire) about EPYC struggling under I/O load came to mind:
Basically, what Linus and Wendell were saying is that Intel has fewer PCIe lanes available but struggles less than EPYC when those PCIe lanes are fully utilized. Wendell hinted at the Intel products being "better engineered" in that regard. Has anyone here seen that in real life? Perhaps, with an all-NVMe NAS similar to what Linus was building?
