let's say I have a cluster with 3 ceph ha identical nodes with a lot of vms in a production environment and another single server(this one have very different hardware in comparision with the other nodes) in a separate network with proxmox and some vms for utilities, like fax management, workstations backups, archived emails ecc, not very important but very usefull for me. is there a way to add this single utility server to the 3 node cluster so I can manage it with the same webui considering that this is in a separate network with different subnet class? I can connect the cluster with extra nic to the same switch of the utilty server but the 3 node cluster is build with a dedicated 10g 10.0.3.0 subnet and the utilty server is 192.168.25.0. I read about ring0 and ring1 cluster configuration but is not very clear to me. I don't need ha or shared disks with this additional node but it will be perfect to take advance from a single webui even for futures updates. thx
