Dell and CoreWeave revealed the installation of the first NVIDIA GB300 NVL72 rack, coinciding with celebratory activities for the 4th of July. This cutting-edge technology is housed within the Dell PowerEdge XE9712 and features a Vertiv CDU at the foundation. Notably, the presence of the EVO logo indicates a connection to Switch data centers, hinting that these racks, while impressive, may not represent the maximum power density capabilities of the facility. Designed to accommodate around 2MW of power per rack, these EVO units utilize 0.250MW for air cooling and an impressive 1.75MW for direct-to-chip liquid cooling.
The new GB300 or Grace Blackwell Ultra substantially increases computative resources and memory, pushing the NVL72 platform’s memory capacity to an astounding 21TB.
Accompanying this rack is the utilization of ConnectX-8 NICs paired with NVIDIA Quantum-X networking by CoreWeave, indicating a shift towards InfiniBand communication for their East-West scale-out network.
While numerous installations of the GB200 NVL72 are ongoing, this installation appears to be an early deployment of the GB300. The investment for a GB200 NVL72 system sits around $3.7 million, with the GB300 likely costing even more due to its expanded liquid cooling requirements and enhanced accelerator features.
