Neocloud CoreWeave claims it has the first Nvidia Vera Rubin NVL72 server rack operational.

In a post on X, the company wrote: "The rumors are true. Proud of the CoreWeave engineering team and our partners (like Dell) who are the first to have a fully working Nvidia Vera Rubin NVL72, achieving yet another major milestone in bringing next-generation AI infrastructure online."

Michael Dell, founder, chairman, and CEO at Dell Technologies, confirmed the deployment in his own LinkedIn post, writing: "The world’s first Nvidia Vera Rubin NVL72 server rack is here. We’re thrilled to deliver the first working, liquid-cooled Dell Technologies PowerEdge XE9812 for CoreWeave — built for the next era of AI infrastructure."

While CoreWeave is claiming to be the first to achieve the milestone, in March, Microsoft said it was "the first cloud to bring up an Nvidia Vera Rubin NVL72 system for validation, another big step in building the next generation of AI infrastructure with Nvidia."

The Rubin platform comprises six chips in total – the NVLink 6 Switch, ConnectX-9 SuperNIC, BlueField-4 DPU, and Spectrum-6 Ethernet Switch, in addition to the Vera CPU and Rubin GPU. Vera is the successor to Nvidia’s Grace CPU, while Rubin will succeed Blackwell GPUs, with Nvidia claiming Rubin will be capable of achieving 5x and 3.5x of inference and training performance, respectively, compared to Blackwell.

The NVL72 system - Nvidia's rack-scale offering that comprises 36 CPUs and 72 GPUs - differs from the Vera Rubin generation in that it is 100 percent liquid-cooled and features cable‑free modular tray designs, which Nvidia claims will allow installation times to be reduced from two hours to five minutes.

Vera Rubin chips have been in full production since January 2026, according to Nvidia's CEO Jensen Huang.
