iGenius launches one of the world's largest sovereign AI data centers, leveraging Vertiv infrastructure, Nvidia GPUs, and Omniverse platform.

Vertiv, NVIDIA, and AI pioneer iGenius have announced a groundbreaking collaboration to deploy Colosseum, one of the world's largest NVIDIA DGX AI supercomputers with NVIDIA Grace Blackwell Superchips, in southern Italy in 2025. Designed as a sovereign AI data center for regulated workloads, Colosseum addresses the stringent data security and sovereignty requirements of highly regulated industries including finance, healthcare, and public administration. As a NVIDIA DGX SuperPOD strategically positioned in southern Italy to meet regional government requirements, Colosseum represents a significant milestone in Europe's AI landscape. "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. "We're demonstrating how modular systems and software-specific infrastructure enable a new era of mission-critical AI."

The system combines Vertiv's infrastructure management expertise, NVIDIA accelerated computing, and the NVIDIA Omniverse Blueprint for AI factory design and operations. Colosseum leverages Vertiv's 360AI reference architecture infrastructure platform for data center power and cooling, designed for the NVIDIA GB200 NVL72, which was co-developed with NVIDIA and released in late 2024. The modular and scalable architecture positions iGenius to deploy one of the fastest hyperscale AI supercomputers and one of the largest to support sovereign AI. Vertiv has extended its reference design library with co-developed data center power and cooling designs for NVIDIA GB300 NVL72, enabling customers to plan infrastructure before silicon arrives. "The unit of compute is no longer the chip — it's the system, the AI Factory," said Karsten Winther, president of Vertiv, EMEA. "Through our collaboration with NVIDIA and visionary AI player iGenius, we are proving the efficiency and system-level maturity of delivering the data center as a unit of compute."

Colosseum was co-designed as a physically accurate digital twin developed with NVIDIA Omniverse technologies, enabling real-time collaboration between Vertiv, iGenius, and NVIDIA to accelerate system-level decisions and compress the design-to-deploy cycle. The Omniverse Blueprint enables real-time simulations, allowing engineers to test and refine designs instantly, reducing simulation times from months to hours. This collaborative 3D design process validated the entire infrastructure stack, including predictive modeling of thermal load, electrical flow, and site layout for 132kW liquid-cooled racks and modular power systems, before a single module was built. "With physically-based digital twins enabled by NVIDIA Omniverse technologies and Vertiv's modular design for the iGenius DGX SuperPOD data center, Colosseum sets a new standard for building supercomputers for the era of AI," said Charlie Boyle, vice president of DGX platforms at NVIDIA.

Vertiv's AI-ready prefabricated modular data center solution includes power, cooling, management, monitoring, service and maintenance offerings, with power and cooling capacity supporting up to 132kW per rack initially, with the ability to scale up for future designs. The infrastructure will leverage NVIDIA Mission Control for data center operations and orchestration, alongside Vertiv Unify to simplify and synchronize building management for AI factories. Through its integration of NVIDIA Omniverse technologies, Vertiv Unify enables real-time updates between physical systems and digital models, allowing predictive maintenance and what-if simulations. Vertiv manufacturing and factory integration processes reduce deployment time by up to 50% compared to traditional data center builds. Colosseum represents more than a single data center—it is a template for scalable, repeatable sovereign AI factories designed to be deployed globally, with iGenius, Vertiv, and NVIDIA aligned on future platform support including DGX GB300 systems and beyond.
