CoreWeave just became the first company to validate Nvidia’s Vera Rubin NVL72 rack for production use. The system, which arrived from Dell Technologies on May 31, passed Nvidia’s L11 diagnostics and a comprehensive 147-hour testing suite, clearing the way for deployment in the second half of 2026.
What’s inside the rack
The Vera Rubin NVL72 is a single liquid-cooled rack containing 72 Nvidia Rubin GPUs and 36 Nvidia Vera CPUs.
Nvidia says the NVL72 delivers up to 4x better training performance and 10x improved inference performance per watt compared to its predecessors.
CoreWeave developed custom software, including a Kubernetes-native orchestrator called Rack Lifecycle Controller, that manages the entire NVL72 as a single programmable entity.
