Capacity isn't the whole story.
Performance, cost, operations, growth and recoverability all matter. A storage design is only useful when it survives real life.
Enterprise IT, storage, architecture, disaster recovery. The stuff people barely notice when it works, and absolutely notice when it doesn’t.

There’s a particular satisfaction in turning a complicated problem into a simple, supportable answer. That’s the work I find interesting: storage, backup, infrastructure design, resilience and the decisions that matter when something goes wrong.
Performance, cost, operations, growth and recoverability all matter. A storage design is only useful when it survives real life.
The only recovery time that counts is the one you've actually tested. Everything else is an assumption waiting for an incident.
Elegant diagrams are great. Systems that are understandable, resilient and maintainable long after handover are better.
