The Quanta D75L-3U is a premier rack-level AI powerhouse, purpose-built for the next generation of AI Factories. By leveraging the NVIDIA MGX™ architecture and advanced liquid-cooling technology, the D75L-3U unlocks the full potential of the NVIDIA Blackwell Ultra platform. Its highly efficient, ultra-dense 3U design enables an industry-leading density of 72 GPUs per MGX rack, providing the foundation for exascale computing.

Pioneering Performance with Blackwell Ultra

  • The Power of Blackwell: Seamlessly supports the NVIDIA HGX™ B300 platform, powered by NVIDIA Blackwell Ultra GPUs. It is engineered to master the world’s most complex Generative AI workloads and Large Language Models (LLM).

  • 800G Fabric with ConnectX-8: Features onboard ConnectX-8 to enable blazing-fast 800G East-West data transfer. This massive bandwidth is critical for building massive-scale GPU clusters, ensuring zero-bottleneck communication across the fabric.

Unmatched Compute Density

  • Optimized Space Efficiency: The D75L-3U integrates the immense power of the HGX™ B300 into a compact 3U chassis, significantly reducing the physical data center footprint compared to traditional 8U or 10U air-cooled alternatives.

  • Extreme Rack-Level Scaling: Purpose-built for the NVIDIA MGX™ rack, the system accommodates up to 9 nodes per rack, achieving an optimal density of 72 GPUs.

Leveraging the NVIDIA MGX™ Ecosystem

  • Accelerate Time-to-Market: By adhering to NVIDIA MGX™ ecosystem, we ensure a stable and reliable supply of critical components—including the rack, power distribution, and cooling manifolds—drastically reducing time-to-market for large-scale deployments.

  • Serviceability & Standardized Compatibility: The D75L-3U integrates seamlessly with the MGX ecosystem, providing superior serviceability and ensuring your infrastructure remains flexible to evolve with future AI hardware generations.
