SoftBank, ZutaCore, and Foxconn Team Up for Integrated Rack Solution Development

Revolutionizing AI Cooling: A Partnership

In a significant leap for the tech world, SoftBank Corp., ZutaCore, and Hon Hai Technology Group—better known as Foxconn—have launched a game-changing innovation in AI server technology. They’ve successfully implemented ZutaCore’s two-phase Direct Liquid Cooling (DLC) technology in a server powered by nVidia’s H200 GPUs. This marks the first time this advanced cooling method has been utilized in such a setting.

But what does this mean for the future of AI and data centers? Well, it’s all about efficiency and sustainability, especially as the demand for AI computing resources continues to skyrocket.

A Peek Inside the Innovation

Back in February 2025, SoftBank demonstrated this new rack-integrated solution at its data center. The results were impressive. Not only did it pass NVIDIA’s rigorous temperature test—known as NVQual—but it also achieved a partial Power Usage Effectiveness (pPUE) of 1.03. This means that for every watt of power consumed, the cooling efficiency was remarkably high. In a world where data centers are notorious for their energy consumption, this is a breath of fresh air.

As AI becomes more entrenched in our daily lives, the need for efficient power use in data centers has never been more urgent. With rising concerns over carbon emissions, it’s clear that innovative cooling solutions like this are not just beneficial; they’re essential.

How Does It Work?

So, how does ZutaCore’s two-phase DLC technology actually work? In simple terms, it cools the heat-generating components—like CPUs and GPUs—by using a special insulating fluid that circulates through a cold plate. When the fluid absorbs heat, it transitions from liquid to gas, effectively removing heat from the server. This process of evaporation and condensation is not only efficient but also allows for higher water temperatures, which improves cooling capacity and reduces water flow rates.

What’s more, the insulating properties of the fluid mean that in the rare event of a spill, your server remains safe from damage. Talk about a win-win!

A Server Designed for the Future

Foxconn has taken the lead in developing an AI server that leverages this revolutionary cooling technology. Their server not only meets but exceeds the performance benchmarks set by NVIDIA. This is a significant achievement, especially when you consider the rigorous standards that come with NVIDIA’s certification.

SoftBank’s rack design is equally impressive. It’s tailored for high-density AI server placement, ensuring optimal airflow and cooling efficiency. With power supply and wiring neatly organized at the back, the design prioritizes safety and ease of operation. Plus, it accommodates both 21-inch and conventional 19-inch servers, adhering to global standards set by the Open Compute Project (OCP).

Voices from the Leaders

The excitement around this collaboration is palpable. Hironobu Tamba, Vice President at SoftBank Corp., expressed the importance of enhancing energy efficiency in data centers to support AI development and a sustainable future. He stated, “The operational demonstration of this rack-integrated solution has confirmed stable operation and improved energy efficiency of high-density GPU servers with liquid cooling.” It’s clear that they are committed to building a sustainable AI infrastructure.

Erez Freibach, Co-founder and CEO of ZutaCore, echoed this sentiment, emphasizing the transformative potential of their waterless cooling technology. He noted, “Together, we are not just meeting today’s challenges but setting a new standard for energy-efficient innovation.” It’s a bold statement, but one that reflects the urgency of our current climate crisis.

Foxconn, as the world’s largest AI server supplier, is equally enthusiastic about this collaboration, eager to leverage their extensive experience in AI server development to drive more value in the global market.

What’s Next?

Looking ahead, SoftBank, ZutaCore, and Foxconn are gearing up to enhance their partnerships with other AI server and rack design companies. Their goal? To push the boundaries of efficiency and low power consumption in AI data centers powered by NVIDIA technology. This collaboration is not just about today; it’s about shaping the future of AI infrastructure on a global scale.

In a world where technology and sustainability must go hand in hand, this partnership is a promising step forward. The future of AI data centers looks brighter, and we can’t wait to see what’s next!

Liquid Cooling: Liquid cooling is a technology used to cool down computer components, such as processors, graphics cards, and other components that generate a lot of heat. It works by circulating a liquid coolant, such as water or a special coolant, through a series of pipes and radiators. The liquid absorbs the heat from the components and then dissipates it into the air. This technology is becoming increasingly popular in the computer industry due to its ability to provide more efficient cooling than traditional air cooling methods. Liquid cooling can also be used to overclock components, allowing them to run at higher speeds than their rated speeds. This technology is becoming increasingly popular in the gaming industry, as it allows gamers to get the most out of their hardware.
