Vertiv has announced a landmark collaboration with NVIDIA and AI pioneer iGenius to deploy Colosseum, one of the world’s largest sovereign AI supercomputers built on NVIDIA DGX infrastructure. Scheduled for deployment in 2025 in southern Italy, Colosseum will deliver mission-critical AI capabilities tailored to highly regulated sectors such as finance, healthcare, and public administration.
The system will be powered by NVIDIA Grace Blackwell Superchips and integrated using Vertiv’s 360AI reference architecture, supporting the NVIDIA GB200 NVL72 platform. Capable of powering 132kW liquid-cooled racks, the modular data center design enables scalable, high-efficiency deployment. Colosseum is also the first deployment to use Vertiv’s newly extended reference architecture for the next-generation GB300 platform, allowing future-proofed power and cooling designs ahead of silicon availability.
The project leverages NVIDIA Omniverse Blueprint for real-time simulation and collaboration, enabling a digital twin of the data center to be validated before deployment. This design approach reduced simulation time from months to hours and is expected to cut deployment time in half. Vertiv’s prefabricated modular system, combined with NVIDIA’s Mission Control and Vertiv™ Unify orchestration software, ensures Colosseum operates as a tightly integrated AI factory — secure, compliant, and optimized for edge inference at scale.
- Colosseum will be one of the world’s largest DGX AI supercomputers, hosted in southern Italy.
- Jointly developed by Vertiv, NVIDIA, and iGenius to serve regulated workloads in sovereign environments.
- Modular architecture with NVIDIA GB200 NVL72 support, scaling to 132kW per rack.
- Designed as a digital twin in NVIDIA Omniverse for predictive modeling and rapid deployment.
- Operated using Vertiv Unify and NVIDIA Mission Control for synchronized, AI-native orchestration.
“Harnessing the power of NVIDIA’s cutting-edge accelerated computing and Vertiv’s innovative infrastructure expertise, Colosseum stands as a testament to the transformative potential of sovereign AI,” said Uljan Sharka, CEO of iGenius.
