POWER DENSITY · 9 MIN READ

What a 120-kilowatt AI rack changes about the building around it

High-density AI hardware is not simply more computing in less space. It changes the cables, switchgear, cooling loops, backup systems, and utility connection around the cabinet.

COOLING · 8 MIN READ

Why a data center’s water story is more complicated than it looks

Coolant can circulate in a sealed loop without being consumed. Water use depends on how the facility ultimately rejects heat—and whether evaporation is part of that design.

THE GRID · 10 MIN READ

Why a data center can’t just plug into the grid

A new power plant does not help a data center unless the transmission network, substations, transformers, and local circuits can deliver that electricity to the exact site.

RELIABILITY · 3 MIN READ

Why backup power doesn’t make a data center invincible

Keeping an AI service available means protecting more than the electricity entering its servers.
