HPE Collaborates with KDDI to Deploy NVIDIA Blackwell Architecture Data Center in Osaka

Recently, HPE and KDDI announced a partnership to jointly operate the Osaka Sakai data center in early 2026. The data center will be equipped with NVIDIA GB200 NVL72 rack level systems built by HPE, based on the latest NVIDIA Blackwell architecture, aimed at providing infrastructure support for AI application development and large-scale language model (LLM) training for startups and large companies.

The Osaka Sakai data center adopts a hybrid cooling technology that combines air cooling and direct liquid cooling to reduce its impact on the environment. KDDI and HPE will also collaborate to promote the services provided by the center, accelerating the widespread adoption of AI solutions among businesses and consumers in Japan and globally.

With the rapid development of AI technology, the demand for large-scale high-performance AI infrastructure is becoming increasingly urgent. To this end, KDDI is building an AI data center in Sakai City, Osaka Prefecture, Japan to support the accelerated development of trillion parameter generative AI models. The center will provide services to organizations and individuals in Japan and around the world who are engaged in the development of generative AI models or require low latency reasoning capabilities. KDDI plans to provide cloud based AI computing services to enterprises through its AI era business platform WAKONX.

The NVIDIA GB200 NVL72 system developed by HPE integrates NVIDIA accelerated computing, networking, and software, optimizing energy efficiency and performance through advanced direct liquid cooling technology. HPE has rich experience in building large-scale AI clusters and 50 years of liquid cooling technology accumulation, which can help KDDI deploy quickly. The system is also equipped with accelerated network technologies such as NVIDIA Quantum-2 InfiniBand, Spectrum-X Ethernet, and BlueField-3 DPU. That provides high-performance network connectivity for diverse AI workloads. Customers can run NVIDIA AI Enterprise platform on KDDI infrastructure to accelerate development and deployment.

HPE President and CEO Antonio Neri stated that the collaboration with KDDI is a key milestone in supporting AI innovation in Japan, as powerful computing capabilities will drive smarter solutions, increase productivity, and promote technological leadership. The Osaka Sakai data center will benefit from HPE’s industry-leading cooling technology, which significantly reduces environmental impact while ensuring high performance. “

Remarks

KDDI President Hiromichi Matsuda said, “We are glad to deploy high-performance GPU infrastructure in the Osaka Sakai data center through our partnership with HPE. HPE’s expertise in supercomputing and advanced cooling technologies will drive the evolution of the next generation of AI data centers. We look forward to working with HPE to challenge the construction of a sustainable future that coexists with AI. “

Both parties stated that they will continue to deepen cooperation, promote industry-leading AI infrastructure construction and innovative service delivery, while improving energy efficiency.
