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…
