NTT Global Data Center’s current cooling portfolio spans multiple models, including immersion systems, direct liquid-to-chip architectures, and hybrid approaches
In sum – what to know:
Cooling complexity drives global knowledge-sharing – NTT is transferring lessons from mature deployments, including immersion cooling in Mumbai, to guide new designs across the US, Europe and APAC.
Scalability and reliability reshape customer demands – Clients now evaluate 100 MW to 1 GW projects, requiring long-term planning, consistent performance and lower environmental impact.
Investment priorities focus on talent and sustainability – Over the next 3–5 years, NTT will emphasize workforce expansion, global growth, advanced cooling models and sustainability embedded at the design stage.
As AI workloads surge and customer expectations rise, NTT Global Data Centers is drawing on global experience, advanced cooling technologies and long-term planning to meet the industry’s next phase of demand, NTT Global Data Centers COO Joe Pace told RCR Wireless News.
Cooling remains one of the most complex challenges, Pace said, adding that NTT Global Data Centers’ worldwide footprint allows it to transfer operational learnings across regions. “We’ve had liquid immersion cooling in Mumbai, India, with 12 megawatts for quite a few years now,” he said. “One of the great things about being a global company is that the lessons you learn in India can be brought to Europe, America, and Asia-Pacific.”
NTT’s current cooling portfolio spans multiple models, including immersion systems, direct liquid-to-chip architectures and hybrid approaches. The choice depends heavily on customer requirements, Pace said, underscoring the need for early collaboration: “A lot of it really depends on the client setup and the client needs.”
Customer expectations are also shifting as deployments grow larger. “One megawatt was a great deal, then 10 megawatts was a great deal, now 100 megawatts is a great deal — and you’re hearing about one-gigawatt deals now,” Pace said. Performance, reliability, and sustainability remain key factors, particularly as clients manage their own downstream obligations.
Enterprises are extending their planning horizons as AI accelerates infrastructure decisions. Pace noted that customers are increasingly selecting sites and designing deployments with future expansion in mind.
Looking ahead three to five years, Pace highlighted four core investment priorities: talent acquisition, global expansion, leveraging NTT’s accumulated cooling expertise and maintaining a sustainability-first approach.
