Description

The NVIDIA Quantum-2 QM9700 is a high-performance InfiniBand switch engineered for AI training clusters, HPC environments, and hyperscale data centers. Delivering 64 ports of NDR 400Gb/s connectivity via 32 OSFP connectors in a compact 1U chassis, it achieves 51.2 Tbps aggregate bidirectional throughput with sub-100ns port-to-port latency. Ideal for NVIDIA DGX SuperPOD deployments and large-scale GPU compute fabrics requiring ultra-low latency RDMA, adaptive routing, and in-network computing acceleration.

FAQs

Q: What is the primary use case for the NVIDIA QM9700 switch?
A: The QM9700 is designed as a spine or core switch for NDR InfiniBand fabrics in AI/ML training clusters such as NVIDIA DGX SuperPOD and HGX infrastructures, as well as large-scale HPC environments running MPI, NCCL, or UCX workloads across hundreds or thousands of GPU nodes. It supports ultra-low latency RDMA for high-performance parallel computing.

Q: How many physical ports does this switch have?
A: The switch has 32 physical OSFP (Octal Small Form-factor Pluggable) connectors. Each OSFP port supports dual 400Gb/s NDR lanes, providing a total of 64 logical 400Gb/s InfiniBand ports. These can also be split to deliver up to 128 x 200Gb/s ports if required.

Q: What is SHARP technology and how does it benefit this switch?
A: SHARP (Scalable Hierarchical Aggregation and Reduction Protocol) v3 is NVIDIA's in-network computing technology that offloads collective communication operations from the CPU to the switch hardware. On the QM9700, SHARPv3 supports up to 64 parallel flows, providing 32x higher AI acceleration compared to previous generations and significantly improving application performance for distributed training and HPC workloads.

Q: Is this switch compatible with Ethernet networks?
A: No, the QM9700 is an InfiniBand-only switch and does not support Ethernet. It is designed exclusively for NDR InfiniBand fabrics. For connectivity, it requires InfiniBand-compatible adapters such as NVIDIA ConnectX-7 NICs and InfiniBand cables or transceivers (OSFP passive/active copper or active optical cables).

Q: What management options are available for the QM9700?
A: This is an internally managed switch variant (MQM9700-NS2F) featuring an on-board subnet manager for simple out-of-the-box deployment supporting up to 2,000 nodes. It can be managed via CLI, SNMP, or NVIDIA UFM (Unified Fabric Manager) software for unified fabric monitoring, real-time analytics, and troubleshooting across the InfiniBand network.
