Fred Miller, Craig Peterson, John Hauge, and Curt Williams discuss how rising GPU and CPU power density is driving liquid cooling adoption, improving power usage effectiveness (PUE), and reshaping efficient, reliable data center design.

Why this matters now

Each new generation of chips changes what data center facilities have to do. Power densities are climbing, cooling requirements are shifting, and the time between architectural changes keeps shrinking. Owners building today have to design for hardware they can only partly anticipate. Decisions about power topology, cooling architecture, and layout flexibility shape whether the building serves its purpose for years or has to be reworked sooner than expected.

What leaders are weighing

Data center leaders are weighing the cost of designing for future chip generations against the risk of building for a snapshot in time. They are deciding how far to push liquid cooling, how to size electrical infrastructure, and how to design for rack densities that may double or triple. There are tradeoffs around space planning, redundancy strategy, and the ability to retrofit without major disruption. Owners want longevity. Operators want reliability under changing loads. The right design choices respect both the silicon roadmap and the practical realities of construction and operation.

How Salas O’Brien is helping clients respond

Our data center team helps owners design facilities that hold up across multiple chip generations without overspending on speculation. We bring deep electrical, mechanical, controls, and operations expertise together with a clear-eyed view of where the industry is heading. We help clients identify which design choices preserve optionality, and which lock them in. Hear Fred Miller, John Hauge, Craig Petersen, and Curt Williams talk through how to design for what’s next.
