Where do you see the load balancing feature? Searching for exactly that was what got me to ProxLB. I have HA groups and fences, but that’s less resource allocation than failure resolution in my experience. My cluster is 8.2.7.
I posted to the forums, but I got a “YMMV” kind of answer; the docs say it’s technically unsupported: https://pve.proxmox.com/pve-docs/chapter-qm.html#_requirements
The hosts have CPUs from the same vendor with similar capabilities. Different vendor might work depending on the actual models and VMs CPU type configured, but it cannot be guaranteed - so please test before deploying such a setup in production.
I’m setting the CPU Type to x86-64-v2-AES which is the highest my westmere CPU’s can do. I have a path to getting all 3 nodes to the 6525 hardware, pending some budget and some decomm’s at work.
I’ve read extensively about that, and this thread was very helpful, and my understanding is that’s still not really a DRS equivalent, but more of a recovery mode: https://forum.proxmox.com/threads/ha-cluster-resource-scheduling-filling-in-the-missing-pieces-from-the-docs.139187/
