Proxmox Cluster Ideas
(alien.top)
I don't see why you'd want separate clusters, just stick em all in one.
Are all nodes dedicated to labbing or do you have some HomeProd services running as well?
One thing to keep in mind with clusters is quorum. You need "half the nodes +1" up and running for the cluster to operate normally. Having isolated servers circumvents this.
I ran into this when I built a test cluster with 5 nodes. Found out I needed at least 3 nodes powered on to do anything. I now have a 2 node cluster (with my laptop running a qdevice for quorum) and 2 isolated nodes. Translates into some decent power savings...
I see no problem putting all the machines into a single cluster. By the way, what are you using for shared storage?
