NVIDIA Quantum-2 QM9790-NS2F 400Gb/s InfiniBand Switch 64-Port NDR Managed Switch with 51.2 Tb/s Throughput | P2C Airflow
for HPC & AI Data Centers Product Overview The NVIDIA Quantum-2 QM9790-NS2F belongs to the QM9700 series of fixed-configuration switches,
setting a new benchmark for 400Gb/s InfiniBand performance. Housed
in a compact 1U chassis, this managed switch delivers 64
non-blocking ports at 400Gb/s per port, translating to an aggregate
bidirectional throughput of 51.2 terabits per second. Designed to
meet extreme-scale AI and high-performance computing demands, the
QM9790 integrates advanced in-network computing via NVIDIA SHARPv3
technology, adaptive routing, RDMA, and congestion control. The
"NS2F" variant indicates power-to-connector (P2C) airflow, ideal
for data centers requiring front-to-rear cooling. Key Features
Technology: In-Network Computing & SHARPv3 NVIDIA Quantum-2 platforms integrate the third generation of
Scalable Hierarchical Aggregation and Reduction Protocol (SHARPv3).
Unlike conventional networking where data must travel back and
forth between compute and storage, SHARPv3 performs data reductions
inside the network fabric. For AI and scientific workloads, this
reduces the volume of data traversing the fabric, dramatically
improving runtime performance. Combined with Remote Direct Memory Access (RDMA) and adaptive routing, the QM9790-NS2F eliminates congestion hot spots and extracts
maximum throughput from GPU clusters. Typical Deployments

Frequently Asked Questions Q: What is the difference between QM9790-NS2F and QM9700-NS2F? A: QM9790-NS2F is an unmanaged switch designed for environments where external fabric manager
(NVIDIA UFM) handles control plane, while QM9700 includes an
on-board subnet manager for standalone management up to 2000 nodes.
Both offer identical port density and performance. Q: Can I use QM9790-NS2F with 200G adapters? A: Yes, using port-split technology, each 400G OSFP port can split
into 2x200Gb/s, effectively providing up to 128 ports of 200G.
Compatible with NVIDIA ConnectX-6 HDR adapters. Q: Which optics/cables are officially compatible? A: The switch supports OSFP connectors; passive/active copper
cables, active fiber cables, and optical modules. We recommend
NVIDIA-qualified cables for maximum reliability. Precautions
