Siemens, alongside Nvidia and Fluence, has launched a reference architecture intended for data centres supporting Nvidia’s AI factory platforms.
The design, which also incorporates input from nVent, is tailored for operators of hyperscale, colocation, and specialised cloud infrastructure facilities aiming to deploy Nvidia DSX Vera Rubin NVL72 infrastructure.
Access deeper industry intelligence
Experience unmatched clarity with a single platform that combines unique data, AI, and human expertise.
The reference design is specified for a total facility capacity of 136MW, with 100MW dedicated to IT load.
The electrical, power and controls solution spans from a nominal 34.5kV utility connection through to the rack interface, providing medium-voltage distribution and modular low-voltage power blocks.
The approach emphasises scalability, allowing phased capacity increases from tens to potentially hundreds of megawatts without requiring a fundamental redesign.
The architecture supports Tier III concurrent maintainability, which enables the removal of individual components from service without impacting data centre operations.
nVent-aligned electrical design parameters have been integrated to ensure compatibility with Nvidia workloads and system architectures. A supplemental design to address advanced thermal management capabilities is expected in future releases.
According to Siemens, integration with Fluence’s battery energy storage contributes resilience and flexibility, particularly for facilities operating in environments where power availability may be constrained.
The reference design also features a centralised data centre management suite, which offers operators unified oversight over power, cooling, and compute systems.
The underlying goal is to address increasing demands presented by the adoption of advanced AI hardware, such as the Nvidia Vera Rubin NVL72, which pushes limits on rack density and efficiency.
Siemens US smart infrastructure president Ruth Gratzke said: “Siemens’ deep expertise in power systems and controls engineering, modular infrastructure, protection, and industrialised delivery is really evident in this latest joint reference architecture design.
“Our pre-engineered, prefabricated, and factory-tested medium- and low-voltage skids help minimise on-site construction complexity, shorten commissioning cycles, and improve quality, safety, and repeatability across deployments.
“Further, our automation and digital twin strategies deployed in this reference help ensure that facilities are brought online faster and with greater potential to produce tokens at scale.”
Siemens stated that its portfolio of electrical systems and infrastructure software, incorporating IoT-enabled devices, AI applications, and cloud-based services, is designed to help operators meet the requirements of increasingly demanding AI-driven data centre workloads.
Last month, Nvidia and IREN, a vertically integrated AI Cloud provider, partnered to accelerate the rollout of up to 5GW of AI infrastructure, with an associated investment right of up to $2.1bn.
