The NVIDIA Quantum-2 QM9790 Series is a groundbreaking 400G InfiniBand switch designed for next-generation high-performance computing (HPC) and artificial intelligence (AI) data centers. With 64 non-blocking ports delivering 400Gb/s each, it offers an aggregate bidirectional throughput of 51.2 Tb/s and over 65.5 billion packets per second. This switch series is engineered to handle extreme-scale workloads, providing unparalleled speed, low latency, and advanced in-network computing capabilities.
The QM9790 leverages NVIDIA's third-generation SHARP (Scalable Hierarchical Aggregation and Reduction Protocol) technology, SHARPy3, which enhances AI acceleration by 32x compared to previous generations. It also supports Remote Direct Memory Access (RDMA), adaptive routing, and advanced Quality of Service (QoS) features to ensure efficient data handling and minimal latency.
The switch operates by utilizing a non-blocking architecture that ensures all ports can communicate simultaneously at full bandwidth. It employs adaptive routing to dynamically manage data paths, reducing congestion and optimizing performance. SHARPy3 performs data aggregation and reduction within the network, offloading computation from servers and significantly reducing data movement.
