I’ve been playing with the Dell Wyse 5060 I bought before and I …. might have bought a few more. I was so impressed by the performance for $35, the CPU and GPU were very functional, and the system had enough SSD storage and RAM to do actual real work. So, considering people have tried to run Proxmox on the Raspberry Pi 4, these things must be adequate for a Proxmox HA cluster. Proxmox has a ton of clustering features, so using these cheap thin clients I was able to play with Proxmox’s HA and migration features. A fun bit of experimentation for sure.
This is part of the Hyper-Converged Cluster Megaproject.
