About this tool
Frequently asked questions
How much RAM does Proxmox / virtualization need?
16 GB is the sensible minimum, 32 GB covers most real setups, and 64 GB gives comfortable headroom.
How many CPU cores does Proxmox / virtualization need?
4 cores are the minimum, 8 cores the sweet spot, and 16 cores comfortable when shared with other services.
Can I run several services on one machine?
Yes — most services share resources. Use the planner and select several services; the engine sums and overlaps the requirements instead of stacking them.
What if I already have hardware?
Register it in My hardware and the analysis shows exactly which services your current system can comfortably run — including an honest “do nothing”.
