From Liquid Cooling to BYO-Power: 4 Key Trends Shaping Data Centers
The Purkay Labs team recently returned from the 7x24 Exchange Conference in sunny Orlando, Florida. As always, the sessions were valuable—but the real insights came during hallway conversations and informal discussions with peers across the industry.
The overarching message? The data center industry is expanding rapidly, driven by AI and high-density workloads. The challenge now is to ensure that this growth remains both sustainable and resilient.
Here are the top takeaways from the event:
1. The AI Surge Shows No Signs of Slowing
AI continues to drive massive increases in compute demand. What once seemed high-density—like 50kW racks—is now dwarfed by systems reaching 500kW, even pushing toward 1MW per rack. These workloads rely on tightly clustered GPU systems and are fundamentally reshaping data center design and operations.
2. Liquid Cooling Is on the Rise
Beyond 50kW, air cooling hits its limits. The industry is now actively piloting solutions such as cold plates, direct-to-chip cooling, and immersion systems. That said, air cooling still manages 20–40% of the load in many high-performance environments.
3. Liquid Cooling Isn’t Plug-and-Play
There are real hurdles: fluid cleanliness, risk of leaks, operational complexity, and uncertain failure protocols. Many current solutions are bespoke or “boutique” systems. Over time, we expect to see best-in-class solutions emerge and become industry standards—but for now, many operators are watching cautiously from the sidelines.
4. Power Constraints Are a Growing Barrier
AI’s appetite for power is massive, and utilities are struggling to keep up. There’s a growing shift toward “Bring Your Own Power” (BYOP) strategies. Solutions discussed included geothermal (as piloted by Google), hydrogen, small modular nuclear reactors (SMRs), and even leveraging stranded natural gas. Some of these ideas are 5–10 years away from deployment, but planning is already underway.
In Conclusion:
The AI revolution is accelerating change across the data center landscape. Cooling strategies, power sourcing, and facility design are all being reimagined. While uncertainty remains, this industry has a proven track record of solving complex challenges—and that momentum isn’t slowing down.
