Licensing shifts dictate architecture.
Migrating off VMware isn't just swapping hypervisors. It involves storage re-architecture, staffing, backup compatibility, and rollback plans.
Operator control room for modern infrastructure
Build the Plan B before your stack forces one on you.
Mr.PlanB turns Proxmox, Kubernetes, storage, backup, and VMware migration complexity into a live operator playbook. The goal is not prettier dashboards. The goal is better decisions under pressure.
CoverageProduction Ready
Real-world infrastructure: migration, storage, disaster recovery, and homelabs.
From emergency VMware exits to clustered ZFS pools and 3 AM restore drills—every guide here is built from real production fire drills, not vendor marketing brochures.

The Challenge
Infrastructure gets painful when you only find the edge cases in production.
Teams hit the same wall over and over: hidden licensing price hikes, complex storage gotchas, and fragile automation scripts that break during maintenance. Mr.PlanB gives you the practical runbooks to avoid those traps.
Storage decisions dictate restore speed.
ZFS, Ceph, and PBS should be judged by how quickly you can recover when disks fail, not just synthetic IOPS benchmarks.
Automation without guardrails creates chaos.
Helper scripts are only useful when you know exactly what they do under the hood and how to recover when something fails.
Scroll walk-through
Move down the rack and watch the operator workflow come into focus.
This section maps the site like a corridor inside a live data hall: you move from detection to recovery, and the currently centered module surfaces the context that matters.
