Siemens Introduces NVIDIA DSX Vera Rubin-Aligned Data Center Blueprint for Scalable AI Factory Infrastructure

Data center reference design NVL72 focuses infrastructure requirements on speed, efficiency, and reliability

(IN BRIEF) Siemens, together with NVIDIA and Fluence and incorporating nVent-aligned design considerations, has developed a reference architecture for NVIDIA DSX Vera Rubin NVL72 AI data centers. The design translates NVIDIA’s AI factory concept into an industrialized electrical, power and controls architecture for hyperscalers, colocation providers and specialized cloud infrastructure operators. Sized for a 136 MW facility with a 100 MW IT load, the architecture covers the full power path from the utility connection through medium-voltage distribution, modular low-voltage power blocks and the rack interface. It is built around repeatable and scalable deployment units, targets Tier III concurrent maintainability and supports phased expansion from tens to hundreds of megawatts without fundamental redesign. The blueprint also integrates Fluence battery energy storage, nVent-aligned design parameters, Siemens automation and digital twin strategies, and a centralized management suite to improve deployment speed, reliability, resilience and operational visibility for high-density AI infrastructure.

(PRESS RELEASE) ZUG, 1-Jun-2026 — /EuropaWire/ — Siemens has worked with NVIDIA and Fluence to develop a reference architecture designed specifically for NVIDIA AI data centers, creating an industrialized electrical, power and controls blueprint for the next generation of high-density AI factory infrastructure. The architecture also incorporates nVent-aligned design considerations to support compatibility with advanced NVIDIA workloads and system requirements.

The new reference design is aligned with NVIDIA DSX Vera Rubin NVL72 and is intended for hyperscalers, colocation providers and specialized cloud infrastructure operators preparing to deploy large-scale AI factories. It translates NVIDIA’s AI factory concept into a deployable infrastructure model focused on speed, efficiency, reliability and long-term scalability.

As AI factories place growing pressure on data center infrastructure, platforms such as NVIDIA Vera Rubin NVL72 are increasing requirements for power delivery, cooling performance, grid connectivity and operational resilience. Operators must now address site selection, grid interconnection, capital efficiency and time-to-revenue while integrating increasingly advanced technologies into mission-critical facilities.

Siemens’ DSX Vera Rubin NVL72 reference design is sized for a total facility capacity of 136 MW, including a 100 MW IT load. The design provides an end-to-end electrical, power and controls architecture covering the path from the utility connection at a nominal 34.5 kV through medium-voltage distribution, modular low-voltage power blocks and ultimately to the rack interface.

The baseline architecture targets Tier III concurrent maintainability, allowing any single component to be removed from service without disrupting IT operations. Built around repeatable and scalable electrical building blocks aligned with NVIDIA DSX Vera Rubin deployment units, the design enables capacity to be added in phases, from initial deployments of tens of megawatts to hundreds of megawatts or more, without requiring a fundamental redesign.

The reference design includes nVent-aligned electrical parameters to support NVIDIA workloads and system architectures. A planned supplement is expected to expand the architecture with advanced thermal management capabilities.

Sara Zawoyski, President of nVent Systems Protection, said nVent has deployed more than two gigawatts of liquid cooling capacity worldwide. She said this operational experience enables the company to help partners such as Siemens convert reference architectures into deployable thermal solutions that perform reliably from the start, particularly as platforms such as NVIDIA Vera Rubin NVL72 push rack densities beyond the limits of traditional air-cooled infrastructure.

The DSX Vera Rubin reference architecture is designed to help AI factory owners and operators deploy extreme-density AI infrastructure more quickly, with lower execution risk and greater predictability. It also preserves flexibility for future IT generations and changing energy requirements. Designed to support DSX MaxLPS, the architecture is intended to help AI factories maximize computing output and token production within fixed power limits.

Ruth Gratzke, President of Siemens Smart Infrastructure USA, said the joint reference architecture demonstrates Siemens’ expertise in power systems, controls engineering, modular infrastructure, protection and industrialized delivery. She said Siemens’ pre-engineered, prefabricated and factory-tested medium- and low-voltage skids are designed to reduce on-site construction complexity, shorten commissioning cycles and improve quality, safety and repeatability across deployments.

The architecture also includes automation and digital twin strategies intended to support faster facility commissioning and help operators scale token production more effectively.

Fluence’s battery energy storage technology is included as part of the blueprint, providing flexibility and resilience for AI factories operating in power-constrained environments. Jeff Monday, Chief Growth Officer at Fluence, said the company’s Smartstack platform can help transform the grid into an accelerator for compute by delivering capabilities such as voltage and frequency ride-through, black start, grid demand response and AI load smoothing.

The design is also integrated with a centralized Integrated Data Center Management Suite, giving operators a single-pane-of-glass view across power, cooling and compute infrastructure.

Siemens said its portfolio of industrial-grade electrical systems, intelligent infrastructure, power distribution, automation and energy management software is designed to support reliable, efficient and sustainable operation of mission-critical facilities. By combining IoT-enabled hardware, AI applications, cloud-based software and digital services, the company aims to help data center operators scale confidently for AI-driven workloads.
