Proxmox Cluster Planner

Live now

Helps you design a realistic Proxmox cluster before purchasing hardware — covering node count, CPU and RAM allocation, storage strategy, and VM versus container placement for your intended workloads.

Interactive tool Structured result Recommended next steps

Best for

Homelab builders and infrastructure planners who want to avoid costly sizing mistakes before committing to Proxmox hardware purchases.

Who this tool is for

Homelab builders and infrastructure planners who want to avoid costly sizing mistakes before committing to Proxmox hardware purchases.

What this tool checks

How many nodes your workload realistically requires and whether clustering is needed at all
CPU and RAM headroom requirements given your planned VM and container mix
Storage strategy — whether Ceph, ZFS, local, or NFS fits your redundancy and performance goals
High-availability expectations versus what single-node or two-node setups can actually deliver

What you will get

A realistic cluster design target including node count, per-node specs, and storage layout
A resource allocation guide — how much capacity to reserve for Proxmox overhead versus workloads
Clear guidance on which storage approach makes sense given your budget and redundancy goals
A pre-purchase checklist to validate the design before spending money on hardware
