Proxmox Cluster Ideas (alien.top)

Currently, here's what I'm running:

pve-cluster

2x Dell OptiPlex 3020

i5-4570

4GB ea. (soon to be 16GB)

1x Dell OptiPlex 9020

i5-4570

4GB (soon to be 32GB)

pve-ed-c1

1x HP EliteDesk Pro 800 G1

i7-4790

8GB (soon to be 32GB)

pve-ed-c2/pve-ed-c3

2x HP EliteDesk Pro 800 G1

i5-4570

1 8GB, 1 4GB (both soon to be 32GB)

My primary question here is should I keep the models seperated and make a secondary cluster, or group them all together? Or is there an even better option in my situation?

I'm sure it isn't all too important but I still would like some opinions.

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...
