Product Description

Product Description

NVIDIA Quantum-2 Series Switches: QM9700 & QM9790

Next-Gen Data Center Networking Standard
NVIDIA Quantum-2-driven QM9700/QM9790 switches in 1U form factor integrate:

Extreme Density
64×400Gb/s InfiniBand ports (51.2Tb/s bandwidth, 66.5B PPS) for AI/HPC ultra-fast data pipelines.
Revolutionary Interconnect
400Gb/s tech (sub-100ns latency) with RDMA/adaptive routing eliminates bottlenecks, unleashing compute clusters.
Intelligent Acceleration
NVIDIA aggregation protocol offloads compute to hardware, cutting GPU overhead >30% for higher training efficiency.
Future-Ready Design
1U chassis supports 800Gb/s optical upgrades, providing scalable low-latency foundation for hyperscale data centers.

Virtualization optimization	VL2VL virtual channel mapping to enhance QoS and congestion control.
shock resistance	The reinforced design of port module conforms to GR-63-CORE standard.
MQM9700-NS2F	64 NDR ports, 32 OSFP ports, managed, power to connector (P2C) airflow (forward)
MQM9700-NS2R	64 NDR ports, 32 OSFP ports, managed, connector to power supply (C2P) airflow (reverse)

Network Design and Topology Optimization
The QM9700/QM9790 switches leverage NVIDIA port-split tech to double radix density for 200Gb/s, cutting network design costs. With 128×200Gb/s ports, they form high-density TOR solutions. The two-level Fat Tree topology suits small-to-medium deployments, optimizing power, latency, and space.
Integrated Routing Capabilities
NVIDIA Quantum-2 InfiniBand switches with optional routing enable 1,000+ node cluster expansion, exceeding previous-gen limits. This ensures sustained peak performance for research, AI, and cloud data processing.
