Is this about limits to what the Proxmox folks will officially provide support services for, or perhaps what can be comfortably managed in the Web UI? These are very valid concerns either way, but the Proxmox VE software itself does provide a comprehensive API and that should scale quite a bit higher.

Proxmox VE configuration database has limitations compared to even simple HA vcenter setup, from my understanding the 30 MBs of configuration data it can hold is for all or nearly all configuration information, and has issues with synchronization timing out above a certain number of nodes.

They do now have "datacenter" single pane of glass interface, but a) it's very new b) no idea how the integration between different Proxmox VE clusters compares to integration between VMware clusters.
