NVIDIA Quantum MQM8700-HS2R 200G InfiniBand Switch | 40-Port 16Tb/s Managed Switch with C2P Airflow

The NVIDIA Quantum QM8700 series (including MQM8700‑HS2R) represents a new class of 200G InfiniBand smart switches, engineered to eliminate bottlenecks in AI, high‑performance computing, and cloud storage environments. With up to forty 200Gb/s ports in a compact 1U form factor, the switch delivers 16 Tb/s aggregate throughput with cut‑through latency below 130 nanoseconds. Built on NVIDIA’s scalable InfiniBand architecture, the MQM8700‑HS2R features an embedded x86 dual‑core processor, integrated Subnet Manager (up to 2,000 nodes), and support for NVIDIA SHARP™ technology, accelerating collective operations by offloading communication from servers to the network fabric.

Designed for extreme flexibility, each 200Gb/s QSFP56 port can be split into two independent 100Gb/s ports, doubling the radix for dense top‑of‑rack deployments. The MQM8700‑HS2R variant (C2P airflow) is a fully managed switch running MLNX‑OS®, ideal for enterprises seeking high‑performance networking with simple out‑of‑the‑box management, CLI, WebUI, SNMP, and JSON APIs.

• 200Gb/s InfiniBand per port – forty QSFP56 ports supporting 200G or 100G split modes, non‑blocking architecture.
• In‑Network Computing Acceleration – NVIDIA SHARP™ technology enables in‑switch data aggregation, reducing MPI, NCCL, and SHMEM communication time by orders of magnitude.
• High Radix & Split Capability – Convert 40x 200G ports into 80x 100G ports for double‑density topologies without extra switches.
• Advanced Congestion Management – Adaptive routing, static routing, and quality of service (QoS) to eliminate hot spots and maximize effective fabric bandwidth.
• Integrated Subnet Manager – On‑board SM supports up to 2,000 nodes for quick cluster bring‑up; fully managed via MLNX‑OS.
• Redundant & Hot‑Swappable PSU – 1+1 redundant power, 80 Plus Gold certified, ENERGY STAR compliant, with power optimization on partial port usage.
• Comprehensive Management – CLI, WebUI, SNMP, JSON, plus optional UFM™ for external advanced fabric orchestration (MQM8790 variant).
• Backward Compatible – Seamless interoperability with previous InfiniBand generations (EDR, FDR).

Unlike conventional switches that only forward packets, NVIDIA Quantum switches embed scalable hierarchical aggregation and reduction protocol (SHARP) engines directly in the silicon. Data traversing the switch can be processed — aggregated, reduced, or broadcast — without multiple round‑trips to server endpoints. This dramatically accelerates collective operations like all‑reduce, barrier, and broadcast, which are critical for deep learning frameworks (TensorFlow, PyTorch via NCCL) and MPI‑based HPC simulations. The result is up to 10x performance gains for communication‑intensive workloads and reduced CPU overhead, freeing compute resources for actual application processing.

The MQM8700‑HS2R also supports adaptive routing and congestion control algorithms that automatically balance traffic across multiple paths, delivering near‑line‑rate throughput even under high contention.

• AI & Machine Learning Clusters – Large‑scale GPU‑based systems (NVIDIA DGX, HGX) requiring 200G interconnect with SHARP for NCCL acceleration.
• High‑Performance Computing (HPC) – Research labs, national labs, and universities running MPI workloads, weather simulation, and computational fluid dynamics.
• Hyperscale & Cloud Data Centers – Fat‑tree, DragonFly+, and multi‑dimensional torus topologies for scalable, high‑bisection bandwidth fabrics.
• Enterprise & Financial Services – Ultra‑low latency trading platforms and database acceleration requiring predictable network performance.
• Top‑of‑Rack (ToR) & End‑of‑Row – Double‑density 100Gb/s per server connectivity using split port capability.

The QM8700 series works seamlessly with NVIDIA ConnectX‑6, ConnectX‑7, and BlueField DPU adapters, supporting both InfiniBand and mixed fabrics. It is backward compatible with previous InfiniBand speeds (EDR 100Gb/s, FDR 56Gb/s). Fully interoperable with existing NVIDIA Quantum fabric switches, and managed via unified fabric manager (UFM) for telemetry and predictive monitoring. Operating system support includes major Linux distributions (RHEL, Ubuntu, Rocky Linux) and NVIDIA certified GPU servers.

Note: For high‑density 100G deployments using split cables, both managed and unmanaged SKUs provide the same port flexibility. Choose MQM8700‑HS2R for integrated subnet management and full OS access with C2P airflow configuration.

• Superior ROI – Reduce capital expenditure with double‑density 100G port capacity and lower switch count for large fabrics.
• Energy Efficient – Dynamic power scaling based on port utilization, lowering operational costs.
• SHARP™ Acceleration – Up to 10x faster collective communications without consuming host CPU cycles.
• Simplified Management – On‑board Subnet Manager eliminates need for external SM servers for clusters up to 2,000 nodes.
• Scalable Topologies – Native support for Fat Tree, DragonFly+, and Torus to future‑proof data center growth.
• Proven Ecosystem – Backed by NVIDIA cumulative software stack and 24/7 partner support.
