Product Description

Product Description

Scaling Out High-Performance Computing (HPC), AI, Cloud Applications, and Storage Infrastructures with 200G InfiniBand Fixed-Configuration Switches

Faster servers combined with high-performance storage and applications that use increasingly complex computations are causing data bandwidth requirements to spiral upward. As servers are deployed with next-generation processors, HPC, AI, and hyperscale cloud environments will need every last bit of network bandwidth. 
NVIDIA Quantum QM8700 and QM8790 200 gigabits per second (Gb/s) InfiniBand fixed-configuration switches provide up to forty 200Gb/s ports with 16 terabits per second (Tb/s) of non-blocking bandwidth or eighty 100Gb/s ports with full bidirectional bandwidth per port with extremely low latency-an ideal choice for building flexible and scalable data centers at any size.

Collective Communication Acceleration
The QM8700/QM8790 switches integrate NVIDIA's hierarchical aggregation protocol to accelerate HPC and deep learning frameworks (e.g., MPI, NCCL) via built-in hardware, reducing redundant server data transfers and enabling linear aggregation of large data vectors for performance gains.
Network Design & Topology Optimization
High-Density 100Gb/s:With ConnectX-6 adapters, the QM8700 supports 80×100Gb/s ports (200Gb/s ports split into dual 100Gb/s lanes), ideal for high-density rack ToR scenarios.
Flexible Topology Support:Compatible with Fat Tree, DragonFly+, etc., with backward compatibility and rich software ecosystem.

Enhanced Management
QM8700 (Internal Management)
On-board subnet manager enables plug-and-play for 2,000 nodes. Managed via CLI/WebUI/SNMP/JSON with MLNX-OS®.
QM8790 (External Management)
Leverages NVIDIA UFM® for centralized provisioning, monitoring, and maintenance to boost efficiency and reduce OPEX.
Efficient Cluster Building
QM8700/QM8790 Switches:

Cost-effective for HPC clusters with static/adaptive routing, congestion control, and QoS for modern topologies.
Eliminate bottlenecks to maximize bandwidth.
Low-power design with dynamic power savings for partial ports, optimizing TCO and ROI through scalability and energy efficiency.
