Hi all,

I tring to build a proxmox homelab server to run some VMs. I need at least 32 cores as I have to test some SIEMs, create windows AD forest and get log correlations and test some advanced incident response tools.

I have already looked into AMD's Epyc processors, even if Max TDP and yearly running cost is lower on Epyc I think it's not the best buy for my usecase.

The system won't be running 24/7, I will only use it when I have do perform above tests and valuations.

I was thinking of the following setup:

AMD Threadripper 3970X 3.7 GHz 32-Core Processor  
Noctua NH-U9 TR4-SP3 Dual Tower Cooler  
MSI TRX40 PRO 10G ATX sTRX4 Motherboard  
2x Samsung 970 EVO Plus SSD 1 TB  
Corsair RM750x 750W  
8x Crucial Ballistix Sport 3200 MHz 16GB  
Quadro P400 2 GB Video Card  
Dark Base Pro 900 rev.2 Case  

Feedback and input are welcome, particularly from others who have built ThreadRipper for proxmox.

Did you encounter any issues for a similar built?How is the quadro p400 pass-through on proxmox or any other relevant information for the evaluation of the project?

I'm investing in a new Proxmox host to migrate from my existing ESXi setup. Current VM's are:

• Windows Server 2022 running Blue Iris NVR (v5) - 10 cameras

• Lubuntu 20 for Logitech Media Server, Plex Media server, Home Assistant, VPN, Mediawiki, Web Server and file server

• Windows 10 for PVR software & general testbed environment.

Any views on which of the CPU's on this list would be the most sensible option, given the above workload? Do I really need a 12-core 7900X?

Hello,

We are planning on building a shared rig for machine learning. Of course, we are cash-strapped, so we are trying to make the best of it. I have done my share of proxmoxing with 6.4 on a Dell Precision 7810 bi-Xeon a short while ago with Quadro boards and the fun of passing them to the host.

On that new machine, the load would be basically 2 VMs: one of a CAD Software (Solidworks) and another one for a linux for machine learning (Ubuntu). The linux box would have one GPU to start, and grow to two if/when we max it out.

So the motherboard would be running at least 2 or max 3 GPUs, which will be blacklisted in the host and assigned beforehand to each VM.

Xeons are too expensive, and I am looking at getting either a 59xx threadripper or a 7950x Ryzen (aka bleeding edge). Here are my questions:

1. I seem to recall that some logic boards / threadripper or ryzen combos where hit or misses with proxmox. Is this still the case? Is there an up to date list like 'don't touch that one with a 10ft pole'?

2. What is the support for NVidia RTX 30xx (Ti or plain)? I recall some of these would 'code 43' in Windows, so not so good?

Any hints welcome on the strategy etc...
