The 800VDC Rollout: How the AI Factory Power Architecture Is Taking Shape
Everyone agrees 54V is dead above a megawatt. Inside the monopolar-vs-bipolar split, the reference designs, and the supplier ecosystem powering the next generation of AI factories.
An Engineering Overview of AI Factory Design
How AI factories differ from traditional data centers — token throughput as the design product, GPU rack density, rail-optimized networks, power chains, and direct-liquid cooling at scale.
The Whole Data Center: Why PUE Was Never the Whole Story
A decade of optimizing data centers for PUE captured the easy efficiency gains. A life-cycle model of workload, building, grid, and supply chain shows the carbon we can't see now outweighs the carbon we've learned to cut.
