Appendices & Reference Data

No single standard governs an AI data center. Six overlapping regimes do (resilience, electrical installation and safety, thermal, efficiency, hardware and compliance), and they do not map one-to-one. Use this index to pick the exact source text for a contract, RFP or commissioning script.

A reference design is a chain of ratios fixed to one accelerator generation. Scale racks by those ratios; count the shared CDUs, switches and optics at the finished size, pricing each at its own scope. Interpolating between generations or leaving fabric uncounted strands capital.

The guide's irreversible decisions reduce to a handful of arithmetic checks, and this appendix runs them in live calculators backed by reference tables. Get one wrong at scoping and the facility can end up mismatched to the revenue it was built to earn.

A number without a date, source and caveat is a rumor with a decimal point. This appendix is the live, date-stamped register that lets you re-check the guide's volatile headline figures before you bet a slab, an interconnection slot or a financing structure on them.

This appendix gives you three reference layers: a glossary of the terms of art, a worked dependency-schedule exercise, and the primary sources and communities that keep a project team’s decisions current.

A failure mode becomes an outage when it takes down a shared mitigation: one CDU controller, fuel header, storage system or protection setting. Catalog each mode by what it defeats and whether it outruns detection, or the availability model will overstate uptime.

An Ashburn design does not port to Frankfurt or Singapore unexamined. Frequency, code, grid, water law and climate all change across borders and re-decide choices from Parts 3 through 6. This appendix names the deltas that force the redesign.
