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

A Revolutionary Cooling Solution for AI Servers

In an exciting development for the tech world, SoftBank Corp., ZutaCore, and Foxconn have launched a cooling technology that’s set to change the game for AI servers. They’ve successfully implemented ZutaCore’s innovative two-phase Direct Liquid Cooling (DLC) system in an AI server powered by nVidia’s H200 GPUs. This marks the first time such technology has been used in tandem with NVIDIA’s advanced computing capabilities.

In February 2025, SoftBank showcased this impressive feat at their data center, where they demonstrated how this rack-integrated solution not only met but exceeded NVIDIA’s stringent temperature test requirements. This means we can expect a cooling solution that’s not just compatible and stable but also reliable—essential traits for the demanding world of AI.

The Growing Need for Efficiency

As AI continues to make waves across industries, the demand for AI servers is skyrocketing. With more computing power comes greater energy consumption, and that’s a pressing concern for data centers around the globe. The push to reduce carbon emissions has never been more urgent. So, how do we balance the need for powerful AI computing while minimizing our environmental footprint?

Enter SoftBank’s partnership with ZutaCore, which began in May 2024. Together, they’re working on solutions that prioritize low power consumption without sacrificing performance. This collaboration aims to not only enhance efficiency but also pave the way for innovative heat removal techniques that can revolutionize data center operations.

The Features of the New Rack-Integrated Solution

One of the standout features of this rack-integrated solution is its Plug & Play capability. By consolidating various server components—including the two-phase DLC cooling system—into a single rack, installation becomes a breeze. Just connect the equipment, and you’re good to go! This simplicity is a game-changer for AI data centers looking to streamline their operations.

What’s more, ZutaCore’s two-phase DLC technology is nothing short of ingenious. It cools critical components like CPUs and GPUs by using a special insulating fluid that efficiently absorbs heat during its phase change from liquid to gas. This method not only enhances cooling efficiency but also allows for higher water temperatures than traditional systems, ultimately reducing the energy required for cooling. The result? Lower power consumption and a more sustainable approach to AI server management.

Reliability Meets Performance

Foxconn has stepped up to the plate by developing an AI server optimized with ZutaCore’s DLC technology. The server has demonstrated impressive performance metrics, surpassing the benchmarks set by NVIDIA’s certification tests. This means users can expect not only top-tier performance but also the peace of mind that comes with knowing their systems are stable and reliable.

Additionally, SoftBank’s specially designed rack maximizes cooling efficiency while accommodating the latest high-density AI servers. It’s built to be versatile and scalable, ensuring that it can adapt to future needs. The design also emphasizes safety and ease of use, with power supply and wiring neatly organized at the back for hassle-free access.

Voices from the Industry

Industry leaders are enthusiastic about this collaboration. Hironobu Tamba from SoftBank noted, “As we strive to build one of Japan’s largest AI infrastructures, enhancing energy efficiency in our data centers is crucial. Our operational demonstration confirms that this innovative cooling solution can significantly improve performance while promoting sustainability.”

Erez Freibach, CEO of ZutaCore, expressed excitement about the partnership, stating, “This collaboration highlights our waterless DLC cooling technology’s potential to deliver unmatched efficiency while addressing the urgent need for sustainable energy solutions. Together, we’re setting a new standard for energy-efficient innovation in AI data centers.”

Foxconn echoed this sentiment, emphasizing their commitment to driving value in the global AI industry through this partnership.

Looking Ahead

The future looks promising for SoftBank, ZutaCore, and Foxconn as they continue to refine their AI server and rack designs. Their focus on efficiency and low power consumption is not just about meeting current demands but also about paving the way for a more sustainable future in tech. With commercialization on the horizon, it’s clear that this collaboration is set to make a significant impact in the global market.

As we look forward to the evolution of AI and its infrastructure, one thing is certain: innovative solutions like these are essential for a sustainable technological future.

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.
