Servers of different configurations in Proxmox

[badmin]

Good afternoon!
I wanted to clarify two points.
1. Is it allowed to have servers of different configurations in one Proxmox cluster? How bad is it? What problems can this cause?
2. Does Proxmox have an automatic load balancing mechanism for nodes in the cluster? That is, something like the fact that virtual machines migrate themselves from a loaded node to a less loaded one?

Thank you in advance.

1. No, that's not a problem (we also use 3 different pve node configs in 4 node cluster).
2. No, there's no automatic load balancing implemented yet but for vm/lxc ha configs you can define host prio groups to what happen to them when a node failed. Or if you ambitious in (bash ...) programming you don't use "ha" config and do vm/lxc ha+load-balancing (and mem-balanced !!) with systemd services at your own if you want that.
