BERLIN, Oct. 21, 2026 (GLOBE NEWSWIRE) -- GTC Berlin -- NVIDIA today announced that Europe’s leading ecosystem partners are adopting the NVIDIA DSX™ AI Factory Platform to build AI factories that minimize water consumption for cooling and use less power for the same AI output. The platform also helps partners bring new capacity online faster and adapt workload power consumption to support grid reliability.
NVIDIA DSX is a full-stack AI factory reference architecture, co-innovated with the world’s leading infrastructure companies. Compute, networking, storage, software, power and cooling are codesigned as one system — optimized from design to operation.
AI clouds and leading design, construction, energy and cooling providers are using DSX to build and operate infrastructure serving Europe’s enterprises, developers and governments.
“Europe’s technology leadership depends on how efficiently we turn power and infrastructure into intelligence,” said Warren Barkley, vice president of DSX product management at NVIDIA. “NVIDIA DSX brings together the technologies and ecosystem expertise operators need to build responsibly, operate efficiently at scale and bring intelligence to the market faster.”
The NVIDIA DSX platform includes DSX MaxLPS™ for dynamic power allocation, DSX Flex for coordinating workload power consumption with grid conditions, DSX Reference Design for validated infrastructure architectures, DSX Sim™ for simulation, DSX OS™ for infrastructure management and DSX Exchange™ for connecting computing and facility systems. These technologies help operators design, deploy and run AI factories that save valuable resources.
NVIDIA DSX Rethinks Cooling
Conventional cooling towers remove heat by evaporating water, requiring a continual supply of replacement water. NVIDIA DSX reference designs connect liquid-cooled computing with dry-cooler-based heat rejection that avoids evaporation: Cooling liquid absorbs heat from computing equipment and circulates in a closed loop, while outdoor dry coolers, similar to large radiators, release that heat into the air without evaporating water.

Used with DSX Sim, ecosystem partners including PTC are helping create these simulation-ready assets with computer-aided design to enable SimReady workflows that let builders model infrastructure configurations and evaluate power and cooling decisions before equipment is installed. Operators can validate designs earlier, reduce deployment risk and move faster from planning to construction.
Driving Production Readiness With NVIDIA DSX OS
To help operators turn installed infrastructure into productive capacity, NVIDIA is expanding its modular, open source DSX OS portfolio with three components in developer preview:
- NVIDIA Config Manager automates AI factory network configuration.
- NVIDIA Rack Management Service provides rack-level power, inventory, firmware and switch management.
- NVIDIA Cluster Readiness Engine runs distributed workloads to validate GPU clusters before production workloads arrive and isolate failures to specific nodes.
Together with NVIDIA Infrastructure Controller, NVIDIA AI Cluster Runtime and NVSentinel, these components help operators automate infrastructure lifecycle management, maintain consistent runtime environments and strengthen health validation, fault attribution and recovery.
Cloud partners including Aleria, Cassava, CoreWeave, Crusoe, Firmus, Firebird, G42, GMI Cloud, IREN, Lambda, Nebius, Nscale, Radiant, Sharon AI and Volta are exploring the latest components of NVIDIA DSX OS to automate infrastructure lifecycle management, and improve resiliency and reliability.
