Hey Alexandre, When you say 20 nodes with unicast - you're saying they're across subnets?
I ask because we've been looking at doing this, more for a vCenter-like single console to manage all VMs and hosts instead of HA, but I thought I read on the proxmox wiki that it wasn't recommended for larger clusters? Does it work well for you at 20 nodes or are there any config tweaks or gotchas that you've run into?
