Best practice for Proxmox networking?

[HomeLabNerd]

Specs: I have 2x SFP+ ports and 2x 2.5Gb on my Proxmox servers. What is the best practices to use it?

Situation now: I now have the 2x SFP+ aggregated and several VLAN's connect via this to the network and I have 1x 2.5Gb management port with a dedicated ip address. The other 2.5Gb port is not in use.

Best situation: ?

Extra question: If I make backups of my VM's what port use it in my current situation? I have set migration to a separate VLAN on the aggregate 10Gb connection.

If you are running a cluster or plan to, you might consider using the other 2 slower links for the corosync traffic, as it needs it's own dedicated network with low latency/jitter as per the docs. That's best practice anyway that I have read. I use the 10Gb links as LACP trunked on the switch and run the tagged interfaces on the instances. I think it is also possible to setup a bridge (per vlan) and have it tag the traffic, so you can just set the instance to use a given switch depending on what vlan it needs. But in the end, use what works best for your use case.

That was something I didn't know. Something I have to investigate. Thank you.

Yes that was what I meant with aggregation (LACP). I do it the same way. So that is okay.

Someone else a good suggestion?
