Field notes from
the operating floor.
Practical, opinionated writing on data center operations, advisory, and engineering. Calibrated for operators, owners, and investment committees that have to act on what they read.
Articles & long-form guides.
Post-Acquisition Data Center Operations Stabilization in 90 Days
A 30/60/90 stabilization framework for newly acquired data center facilities — the operational moves that prevent the value erosion most acquisitions take in the first quarter.
AI-Ready Data Center Engineering: Liquid Cooling Retrofits for Existing Facilities
How to engineer the conversion of a legacy 5–15 kW per rack data center into a 30–150 kW heavy-density AI environment without rebuilding the hall — practical engineering decisions, not vendor pitches.
Data Center Operational Due Diligence: A Buyer's Checklist
A practical operational due diligence checklist for data center acquisitions — what to validate beyond the technical inspection report, with the questions investors and asset managers actually need answered.
Working data center glossary.
Operator-written definitions of the terms that come up most often in operations, engineering, and diligence work.
PUE is the ratio of total facility energy to IT equipment energy — the most-cited efficiency metric in data center operations.
WUE is the ratio of annual water consumption to IT energy consumption — the standard water-side companion to PUE.
N+1 redundancy means a system has one more component than the minimum required to carry the load, so any single component can fail without losing capacity.
2N redundancy means the system has two complete, independent paths — either alone can carry the full load.
ASHRAE TC 9.9 publishes thermal envelope classes A1 through A4 that define recommended and allowable operating temperature and humidity ranges for IT equipment.
The Uptime Institute Tier Classification System rates data center topologies on availability and concurrent maintainability — Tier I through Tier IV.
An RDHX is a chilled-water heat exchanger mounted on the rear door of a server rack that rejects rack heat to a water loop instead of room air.
Liquid cooling moves heat off IT components using a fluid loop instead of air — required for the densest AI and HPC workloads.
