Description

In the fast-evolving world of high-performance computing and artificial intelligence, having robust, low-latency network hardware is non-negotiable. The Mellanox QM8700-F and MQM8700-HS2F stand as flagship InfiniBand switch models, purpose-built for organizations looking to buy InfiniBand switch solutions that power the most demanding HPC cluster and AI cluster environments. As a 1U high-density platform, this HDR InfiniBand switch redefines what’s possible in data center networking.

At the core of the QM8700-F / MQM8700-HS2F lies the NVIDIA Quantum chip, delivering an astonishing 16Tb/s of non-blocking bandwidth and sub-130ns port-to-port latency. This 1U switch supports 40 ports of HDR 200Gb/s InfiniBand, or 80 ports of HDR100 100Gb/s with ConnectX-6 adapters, making it the ultimate high-density switch for modern data centers. For AI model training and large-scale HPC simulations, this 200Gb switch eliminates network bottlenecks, ensuring data flows at wire speed.

What sets this Mellanox switch apart is its integrated SHARP (Scalable Hierarchical Aggregation and Reduction Protocol) technology, enabling advanced in-network computing. By offloading collective communication tasks from CPUs to the switch fabric, it accelerates AI and HPC applications by orders of magnitude—a critical advantage for AI cluster workloads like distributed deep learning. Whether deployed as a leaf or spine switch, it optimizes traffic routing for SlimFly and Dragonfly+ topologies.

Designed for reliability and ease of management, the MQM8700-HS2F features hot-swappable redundant power supplies and fans, plus P2C airflow for standard data center cooling. Managed via Mellanox’s UFM (Unified Fabric Management) platform, it provides real-time telemetry, AI-driven analytics, and self-healing capabilities that recover from link failures 5,000x faster than software solutions. This ensures maximum uptime for mission-critical HPC cluster and AI cluster operations.

Compatibility

The Mellanox QM8700-F / MQM8700-HS2F is fully compatible with standard 19-inch server rack enclosures and rack rails, making integration seamless in existing data centers. It interoperates exclusively with Mellanox (NVIDIA) ConnectX-6 InfiniBand adapters, supporting both HDR 200Gb/s and HDR100 100Gb/s speeds for maximum flexibility.

This InfiniBand switch is validated for HPC and AI cluster environments, supporting popular topologies like SlimFly, Dragonfly+, and 6DT. It works with leading HPC middleware and AI frameworks, including MPI, PyTorch, TensorFlow, and Horovod, ensuring compatibility with your existing software stack. The switch runs on MLNX-OS, Mellanox’s purpose-built operating system for InfiniBand fabrics.

Management compatibility includes full support for Mellanox UFM (Unified Fabric Management) software, enabling centralized control of multiple switches and end hosts. It also supports out-of-band management via Ethernet and in-band management over InfiniBand, providing flexible options for network administrators. The Mellanox switch is RoHS-compliant and certified for safety/EMC standards (CE/FCC), ensuring global deployment readiness.

Usage Scenarios

The Mellanox QM8700-F / MQM8700-HS2F is the gold standard for HPC cluster deployments, powering scientific computing, weather modeling, and finite element analysis workloads. Its 16Tb/s bandwidth and sub-130ns latency eliminate network bottlenecks, ensuring fast data exchange between compute nodes. Organizations can buy InfiniBand switch hardware to build clusters that scale to thousands of nodes with consistent performance.

For AI cluster environments, this 1U switch is indispensable for distributed deep learning training. The integrated SHARP technology optimizes collective communication operations like all-reduce, which are critical for training large AI models. Whether training computer vision, natural language processing, or generative AI models, the switch accelerates training times by reducing communication overhead between GPU servers.

hyperscale cloud and big data infrastructures benefit greatly from the high-density switch design. The 40-port HDR configuration enables efficient leaf-spine architectures, connecting thousands of servers with high-speed 200Gb/s links. It’s ideal for big data processing frameworks like Spark and Hadoop, where fast data movement between nodes is essential for performance. The switch’s low power consumption (253W typical) also reduces operational costs in large-scale deployments.

As a high-performance server network switch, it excels in storage-intensive environments, connecting NVMe storage arrays to compute nodes with 200Gb/s InfiniBand. This enables low-latency, high-bandwidth access to storage, critical for database, data warehousing, and content delivery workloads. The switch’s reliability and redundancy features ensure data integrity and availability for mission-critical applications.

Frequently Asked Questions

Q1: What is the main difference between QM8700-F and MQM8700-HS2F?
A: The MQM8700-HS2F is a pre-configured model with 2 AC power supplies, P2C airflow, and a rail kit, while the QM8700-F is the base model (same hardware, different bundle).

Q2: What makes this switch ideal for AI clusters?
A: It features **SHARP in-network computing**, which offloads collective communication tasks (e.g., all-reduce) from CPUs/GPUs to the switch, accelerating AI training by up to 10x compared to traditional Ethernet switches.

Q3: Can it be used in both leaf and spine roles in a data center?
A: Absolutely. The InfiniBand switch supports advanced adaptive routing for SlimFly and Dragonfly+ topologies, making it suitable for both leaf (server-facing) and spine (inter-leaf) roles in high-density fabrics.

Q4: What is the maximum number of servers it can connect in an HPC cluster?
A: With 40 HDR 200Gb/s ports, it can connect up to 40 GPU servers directly as a leaf switch. Using HDR100 mode (80 ports), it doubles capacity, supporting up to 80 servers per switch.
