About Mr.PlanB
Hey, I'm Mr.PlanB. I build, break, benchmark, and document infrastructure systems, from multi-node Proxmox clusters and bare-metal Kubernetes deployments to ZFS storage pools and disaster recovery failovers.
Most infrastructure guides online are either shallow marketing whitepapers that skip the failure modes that matter, or scattered forum threads where you have to piece together outdated commands from five different years. Mr.PlanB was started to fix that.
Why "Plan B"?
In production, your "Plan A" is what works on day one when everything is configured cleanly. Your Plan B is what keeps your business or homelab alive when a drive pool degrades, a vendor suddenly triples their licensing fees overnight, or a network partition splits your cluster.
Everything on this site is written with that in mind. We test recovery procedures, document the gotchas before they bite you, and focus on practical steps you can actually run in a real environment.
What you'll find here
- Proxmox VE & homelab architecture: Cluster tuning, high availability, SDN networking, GPU passthrough, and vetted helper scripts.
- Storage & backup engineering: Detailed guides to ZFS, Ceph, PBS (Proxmox Backup Server), and 3-2-1 backup strategies planned around real-world restore speed.
- Platform migration roadmaps: Step-by-step escape plans for teams moving off VMware, evaluating KVM, or deciding between bare-metal and managed Kubernetes.
- Free cloud & infrastructure trackers: Sourced, historical datasets tracking cloud storage limits, free VPS tiers, and uptime monitors.
Books & video guides
If you want a full reference manual, I wrote Proxmox for Everyone, available on Amazon. I also make visual walkthroughs and longer technical explainers on YouTube.
Editorial transparency
We don't publish sponsored fluff or unverified benchmark claims. When we cite data, test commands, or review tools, we do it transparently. You can read the full details in our Editorial Policy.
Whether you're setting up your first home server or migrating a fleet of production hypervisors, I hope these notes save you hours of debugging. If you find something helpful, share it with a fellow engineer!
