Overview
Product overview
The NVIDIA Quantum MQM8790‑HS2R is an unmanaged 200G InfiniBand smart switch designed for large‑scale data center deployments where centralized fabric management is preferred. Part of the NVIDIA Quantum QM8700 series, this switch delivers forty 200Gb/s ports in a compact 1U form factor with 16 Tb/s aggregate non‑blocking throughput and sub‑130ns cut‑through latency. Unlike its managed counterparts, the MQM8790‑HS2R is optimized for external management via NVIDIA Unified Fabric Manager (UFM), enabling data center operators to efficiently provision, monitor, troubleshoot, and maintain modern data center fabrics at scale. Each 200Gb/s QSFP56 port can be split into two independent 100Gb/s ports, providing up to 80 ports of 100Gb/s connectivity — ideal for double‑density top‑of‑rack deployments. The MQM8790‑HS2R features C2P (power‑to‑port) airflow, dual redundant power supplies, and full support for NVIDIA SHARP in‑network computing acceleration.
Key features
- 200Gb/s InfiniBand per port – forty QSFP56 ports supporting 200G or 100G split modes, non‑blocking architecture.
- Unmanaged SKU for External Control – No on‑board Subnet Manager; designed for centralized management via NVIDIA UFM platform.
- 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.
- Redundant & Hot‑Swappable PSU – 1+1 redundant power, 80 Plus Gold certified, ENERGY STAR compliant, with power optimization on partial port usage.
- C2P Airflow Configuration – Power‑to‑port airflow direction ideal for data center cooling schemes that require rear‑to‑front airflow.
- UFM Ready – Seamless integration with NVIDIA Unified Fabric Manager for advanced telemetry, predictive analytics, and automated fabric orchestration.
Typical applications
- Large‑Scale AI & ML Clusters – GPU‑based systems requiring centralized fabric management and telemetry across hundreds or thousands of nodes.
- High‑Performance Computing (HPC) – Research labs, national labs, and universities where external fabric managers provide enhanced monitoring and automation.
- Hyperscale Data Centers – Fat‑tree, DragonFly+, and multi‑dimensional torus topologies managed through UFM for maximum efficiency.
- Enterprise & Cloud Service Providers – Environments requiring unified control plane across multiple switch fabrics.
- Top‑of‑Rack (ToR) with Centralized Management – Double‑density 100Gb/s per server connectivity with fabric‑wide visibility, utilizing C2P airflow for rear‑to‑front cooling designs.
