Hello Everyone,

I am coming from the VMware world. I have never touched Proxmox, but I am planning my first installation. I was hoping to get some feedback on my plans to make sure I am not missing something or planning it wrong. My initial concern is the network configs. This will be a production environment for a small non-profit organization. Any suggestions would be greatly appreciated.

The end goal is to migrate from free VMware to Proxmox and use PBS to back up the new setup.

The setup will be two hosts. Each host has 40 cores, 256GB RAM, local storage, and 8 NICs: 4 10GB and 4 1GB. There are two Cisco switches in a stack for the network.

Planned network config

2 1GB connections in LAG for MGMT (Dedicated VLAN for MGMT with internet access)
2 1GB connections standalone for Cluster (Dedicated and isolated VLAN)
2 10GB connections in LAG for VM Traffic (Dedicated VLANs for VM Traffic with internet access)
2 10GB connection in LAG for Live Migration (Dedicated and isolated VLAN)

Does this look like the best plan, or am I missing something? Any other recommendations that you have for my overall project are greatly appreciated. I am by no means new to technology, but I am as fresh as they get when it comes to Proxmox.
 
Looks good. Not sure if you need a LAG for Management, you could just assign a differnet subnet to each of the adapters, less complexity.

Don't forget to add a qdevice or you will get issues with your 2 node cluster.

And for PBS, it is recommended to use a dedicated host for that. You could add that host (or vm if you have to) into the Live Migration VLAN, backup traffic would not affect the other neworks - i assume you won't be migrating constantly.

Thank you! This is the first I am hearing of qdevice. I was planning to run PBS from a VM on a Synology device. Do you think that PBS would be a suitable place for qdevice or would it need to be its own machine?
 
Better isolate it, create an additional minimal debian vm or debian container on your synology or use a raspberry pi.

*edit*
Depending on your requirements you could just run your PVE hosts standalone, not in a cluster, then you don't need a qdevice.

Downside is you have to manage both hosts on their own, no HA and no easy migration except with PDM.
For manual migrations you could use PDM or backup / restore VM.
