Designing a Very Efficient Data Center

What this post added

This post details the design innovations of the Prineville data center, a key initiative within the Open Compute Project. It highlights the "less is more" philosophy leading to a facility with a PUE of 1.07 and WUE of 0.31 liters/kWH, a 45% reduction in CapEx, and improved reliability. Key innovations include eliminating centralized UPS (replacing with 48VDC at cabinet level), PDUs (using 277VAC distribution), chillers (using 100% outside air evaporative cooling), and ductwork (using dry wall supply air shafts). The post quantifies power loss reductions through these changes and details the custom reactor power panel and DC backup power system.
