At least they're dealing with commercial hardware. Once you get into truly top of the line hardware, especially proprietary HPC interconnects, there are also so many driver/missing feature bugs to deal with. Some things I've heard about, I'm not even sure how they managed to correctly diagnose the problem. Like on one of the supercomputers I've worked on, around 10 years ago, there was an infamous hardware-level failure that only occurred with one application and only when it was doing a full system run of over 10k nodes, using over a PB of RAM. It turns out that memory was being laid out and accessed just right to cause rowhammer faults. Even scheduling the debugging sessions in the queue for such huge full-system jobs must have been a nightmare. Plus, it's not good to have a several hundred million dollar computer consuming megawatts of power offline and not doing useful work.

With the layer 2 traffic Cisco has flying around, you could even have it update in real time and show and log new devices connected even for a short time without asking for an IP. I was told that that wouldn't make sense because its just too much trouble to bother with an app or GUI and the CLI does everything you need better than any GUI ever could.

You obviously don't have much experience with video production. I am not sure what workflows LTT uses, but I know exactly why they need this. They use RED cameras and probably shoot in 8k 90% of the time (those cut ins aren't zooms), or maybe they don't but would like to and can't because they don't have this server up. That may not be a heavy lift if you are one dude at a workstation, but when you have a whole team of editors hitting the same server day in and day out, it can really make scrubbing, editing, NR, grading, rendering, etc. a serious pita. People don't realize just how storage intensive video production is these days. That's one reason LTT goes around helping KZbinrs install their own servers because you don't have to be computer geek to know when you are spending more time watching an hour glass spin than cranking out video. And this doesn't even include compositing which really pushes the envelope and I've seen LTT use, although sparingly.

So it very probably isn't drop damage 😄👌 Pins not having perfect contact is probably the common problem with those EPYC CPUs. Their retention system really isn't perfect. I think the next socket with the cooler pressing the CPUs down, instead of the socket mechanism like now, will improve contact. And it's not obvious to diagnose, but if you know it, it's easy.
