Planning on setting up Proxmox and moving most services there. Some questions (midwest.social)

I am currently running most of my stuff from an unraid box using spare parts I have. It seems like I am hitting my limit on it and just want to turn it into a NAS. Micro PCs/USFF are what I am planning on moving stuff to (probably a cluster of 2 for now but might expand later.). Just a few quick questions:

  1. Running arr services on a proxmox cluster to download to a device on the same network. I don't think there would be any problems but wanted to see what changes need to be done.

  2. Which micro PCs are you running? I am leaving towards HP prodesk or Lenovo 7xx/9xx series around 200 each. I don't really plan on getting more than 2-3 and don't run too many things, but would want enough overhead if I switch stuff over to home assistant and windows and Linux VMs if needed.

  3. Any best practices you recommend when starting a Proxmox cluster? I've learned over time it's best to set it up correctly than try to fix stuff when it's running. I wish I could coach myself from 7 years ago now. Would of saved a lot of headaches lol.

I haven't done it - but I believe Proxmox allows for creating a "backplane" network which the servers can use to talk directly to each other. This would be used for ceph and server migrations so that the large amount of network traffic doesn't interfere with other traffic being used by the VMs and the rest of your network.

You'd just need a second NIC and a switch to create the second network, then staticly assign IPs. This network wouldn't route anywhere else.

In proxmox there's no need to assign it to a physical NIC. If you want a virtual network that goes as frast as possible you'd create a bridge or whatever and assign it to nothing. If you assign it to a NIC then since it wants to use SR-IOV it would only go as fast as the NIC can go.
