NVIDIA launches DSX Ready for AI-factory power and cooling gear
NVIDIA has launched DSX Ready, a qualification program for power and cooling products used in AI factories. The program initially covers battery energy storage systems and coolant distribution units from six suppliers.

NVIDIA is introducing a qualification program for the equipment that supplies power to AI factories and removes heat from their computing systems, giving builders a list of products that meet category-specific requirements tied to its DSX reference designs.
Called NVIDIA DSX Ready, the program launches with two categories: battery energy storage systems, or BESS, and coolant distribution units, or CDUs. NVIDIA says the qualification process is intended to help customers evaluate infrastructure products, reduce integration risk and move from factory design toward deployment with fewer unknowns.
Six suppliers enter the first DSX Ready group
The initial qualified BESS suppliers are Hitachi Energy, LG Energy Solution and Tesla. The first qualified CDU suppliers are LG Electronics, LiquidStack and Vertiv.
Battery energy storage systems can store and dispatch electricity for AI data centers as they respond to power changes, grid disturbances, demand-response programs and transitions between utility and backup power. CDUs circulate coolant through liquid-cooled computing systems while managing temperature, pressure and flow.
NVIDIA’s DSX Ready program page says the designation applies to a specific product or solution, not to an entire company or product portfolio. A supplier can therefore have one qualified offering while other products require separate review.
Qualification does not replace site engineering
The program connects NVIDIA’s broad AI-factory reference architecture to individual equipment choices. DSX covers compute, networking, power, cooling, facilities and software, reflecting the company’s view that changing one part of a high-density facility can move the bottleneck to another.
For BESS suppliers, partners run required qualification tests and submit supporting data for NVIDIA review within a defined qualification boundary. NVIDIA explicitly says passing the process does not replace site-level engineering or establish the stability of a particular facility.
CDU suppliers follow a different route. Their products use a CDU self-qualification suite to determine whether a specific offering meets applicable NVIDIA functional requirements. A qualified CDU can satisfy relevant cooling criteria while still requiring a builder to assess its fit with the facility’s layout, configuration and operating conditions.
DSX Ready is a product qualification, not a data-center approval. Builders still need to validate how each qualified component works in the planned site and operating environment.
Why power and cooling now sit inside the platform
NVIDIA is positioning DSX as a factory-wide system rather than a collection of independent hardware products. Its earlier DSX materials describe tools for modeling facilities, power systems, cooling equipment and computing infrastructure together before deployment, then coordinating operations after the factory begins running.
That approach reflects the demands of newer AI systems. High-density accelerator racks draw substantial power and produce corresponding heat loads, making electrical distribution and liquid cooling part of the compute design rather than separate building services. In its DSX reference materials, NVIDIA has also described designs using warm-water liquid cooling and future 800-volt direct-current distribution for larger AI facilities.
The new qualification label gives infrastructure suppliers a defined path into that system. It also gives builders a way to search for equipment that NVIDIA says has completed the applicable review instead of evaluating every product from the starting point.
More categories are planned
NVIDIA says DSX Ready will expand into additional infrastructure and software categories over time. The company has not provided a timetable or a complete list of future categories in the launch announcement.
The current program is narrow by design: it covers battery storage on the power side and coolant distribution on the cooling side. Those categories address two of the most site-sensitive parts of an AI factory, but the qualification does not cover a complete facility, a full rack installation or a guaranteed operating result.
For now, the practical value of DSX Ready is a shared screening process. Hitachi Energy, LG Energy Solution, Tesla, LG Electronics, LiquidStack and Vertiv have products listed at launch, while customers remain responsible for selecting, engineering and operating those products within their own facilities.
