NVIDIA MQM8790-HS2F Quantum HDR InfiniBand Switch, 40 x HDR QSFP56 ports, two power supplies (AC), unmanaged, x86 dual core, standard depth,P2C airflow, rail kit
NVIDIA QM8790 switch systems provide the highest performing fabric solution in a 1U form factor by delivering up to 16Tb/s of non-blocking bandwidth with sub 130ns port-to-port latency. These switches deliver 7.2 billion packets-per-second (Bpps), or 390 million pps per port. These systems are the industry's most cost-effective building blocks for embedded systems and storage with a need for low port density systems. Whether looking at price-to-performance or energy-to-performance, these systems offer superior performance, power and space, reducing capital and operating expenses and providing the best return-on-investment.
The 140-node DGX SuperPOD uses 40-port NVIDIA QM8790 switches for all three layers. Each cluster SU consists of 20 DGX A100s, with 8 Leaf switches per SU. With each DGX A100 InfiniBand HCA connected to its fat tree topology, the rail-optimized design at both leaf and spine levels significantly boosts deep learning training performance.
Intelligent selection of optimal network paths to reduce latency, alleviate congestion, and achieve dynamic load balancing.
Reduces CPU load, lowers latency, and boosts data transfer speed and bandwidth utilization, enhancing HPC and deep learning performance.
Facilitates collective and point-to-point communication between multiple GPUs, improving data transfer efficiency.
