Product Description

Product Description

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

Collective Communication Acceleration
QM8700/QM8790 fixed-configuration switches integrate NVIDIA to offload in-network computing via silicon hardware. Processing data mid-transmission accelerates HPC/deep learning frameworks (e.g., MPI, NCCL), eliminating redundant server transfers and enabling wire-speed aggregation of ML-critical data vectors for orders-of-magnitude performance gains.
Streamlined Network Design
High-Density 100Gb/s:Paired with ConnectX®-6, QM8700 offers 80×100Gb/s ports (200Gb/s split into dual 100Gb/s lanes), ideal for dense ToR setups to cut network costs.
Flexible Topologies:Supports Fat Tree, DragonFly+, etc., with backward compatibility and broad software ecosystem support.

Enhanced Management
QM8700 (Internal):On-board subnet manager enables plug-and-play for 2,000 nodes; MLNX-OS® provides CLI/WebUI/SNMP/JSON management.
QM8790 (External):Leverages NVIDIA UFM® for efficient network provisioning, monitoring, and maintenance to boost utilization and reduce OPEX.
Efficient Cluster Building
Intelligent Networking:Static/adaptive routing, congestion control, QoS optimize modern topologies and eliminate bandwidth bottlenecks.
Low-Power Design:Industry-leading efficiency with partial-port power saving balances cost/performance, reducing CAPEX/OPEX and maximizing ROI.
