Introduction
NVIDIA InfiniBand switches deliver industry-leading, low-latency, high-bandwidth interconnects designed to power modern AI, high-performance computing (HPC), and data-intensive enterprise workloads. From HDR at 200 Gb/s to the latest Quantum NDR and XDR generations, these switches provide the scalable fabric foundation required for demanding applications such as large-scale AI training, real-time analytics, and scientific simulation. With advanced features such as adaptive routing, congestion control, and hardware-accelerated collective operations, NVIDIA InfiniBand ensures predictable performance and optimal resource utilization across clustered environments.
This product guide covers the following NVIDIA InfiniBand switch offerings, most available in both Port Side Exhaust (PSE) and opposite Port Side Exhaust (oPSE) airflow configurations:

Did you know?
NVIDIA InfiniBand switches do far more than just move data—they actively accelerate application performance through in‑network computing. Using technologies such as SHARP (Scalable Hierarchical Aggregation and Reduction Protocol), these switches can perform collective operations like reductions directly in the network fabric, significantly reducing the amount of data that must traverse the cluster and offloading work from CPUs and GPUs. This capability becomes increasingly important at scale, where communication overhead can dominate workload runtime; by processing data in transit and enabling advanced routing, congestion control, and self-healing behaviors, modern Quantum, Quantum‑2, and Quantum‑3 InfiniBand switches help deliver near-linear scalability for AI training and HPC workloads.

Fabric Manager
For InfiniBand networks to operate, there must always be a Fabric Manager present on the network providing subnet management functionality. The QM8700 Managed HDR InfiniBand Switch and QM9700 Managed NDR InfiniBand Switch come with an on-board Fabric Manager that can be used for this purpose. For all other switches (and as an alternative for the QM8700 and QM9700), an external Fabric Manager will need to be installed on a server that is connected to the InfiniBand fabric using an InfiniBand adapter.
There are two software options available for the Fabric Manager:
- OpenSM
- NVIDIA Unified Fabric Manager
OpenSM is included with the NVIDIA DOCA software package. OpenSM discovers, initializes, and configures InfiniBand fabrics, managing routing paths and switch forwarding tables. It runs in the background to ensure continuous communication between servers and storage. For more information, see the NVIDA DOCA help center and search on OpenSM.
NVIDIA Unified Fabric Manager (UFM) is InfiniBand networking management software that combines enhanced, real-time network telemetry with fabric visibility and control to support scale-out InfiniBand data centers. The two UFM offerings are available from Lenovo:
- UFM Telemetry for Real-Time Monitoring
The UFM Telemetry platform provides network validation tools to monitor network performance and conditions, capturing and streaming rich real-time network telemetry information, application workload usage, and system configuration to an on-premises or cloud-based database for further analysis.
- UFM Enterprise for Fabric Visibility and Control
The UFM Enterprise platform combines the benefits of UFM Telemetry with enhanced network monitoring and management. It performs automated network discovery and provisioning, traffic monitoring, and congestion discovery. It also enables job schedule provisioning and integrates with industry-leading job schedulers and cloud and cluster managers, including Slurm and Platform Load Sharing Facility (LSF).
The following table lists the UFM subscription licenses available from Lenovo.
