MSB7800-ES2F 100Gb/s InfiniBand Switch – 36 x QSFP28, 90ns Latency, Ideal for

36-port managed smart switch for HPC and AI clusters

The NVIDIA Mellanox MSB7800-ES2F delivers 36 ports of 100Gb/s full bidirectional bandwidth in a 1U form factor. With 7.2Tb/s aggregate throughput, 90ns port-to-port latency, and SHARP in-network computing, it is purpose-built for high-performance computing and AI workloads that demand every bit of bandwidth.

The MSB7800-ES2F is a managed member of the NVIDIA Mellanox SB7800 series, built around the Switch-IB 2 ASIC. It provides 36 QSFP28 ports running at Enhanced Data Rate (EDR) 100Gb/s per port. This switch is designed for top-of-rack leaf connectivity and can scale from small clusters to extremely large HPC and enterprise data center fabrics. Its integrated x86 dual-core CPU runs MLNX-OS, enabling comprehensive on-box management including subnet manager for up to 2,000 nodes.

By offloading collective communication operations from the CPU to the switch network via SHARP technology, the MSB7800-ES2F reduces MPI operation time and frees valuable CPU resources for computation. This results in an order-of-magnitude improvement in application performance for parallel workloads.

The NVIDIA Scalable Hierarchical Aggregation and Reduction Protocol (SHARP) technology embedded in the Switch-IB 2 ASIC enables the MSB7800-ES2F to perform collective operations such as MPI reductions directly within the network fabric. This eliminates multiple data traversals between endpoints, drastically reducing MPI operation time and freeing CPU cores for application computation. For fully populated fat-tree networks, partial reduction operations can complete in under three microseconds. This co-design approach accelerates communication frameworks and maximizes effective fabric bandwidth.

• Top-of-Rack Leaf Connectivity – Ideal for spine-leaf architectures in HPC and AI clusters.
• Small to Extremely Large Clusters – Scales from a few nodes to thousands of nodes with integrated subnet management.
• Enterprise Data Centers – Supports high-performance storage, database, and compute workloads requiring low latency and high throughput.
• AI Training and Inference – SHARP acceleration boosts NCCL and MPI-based distributed training performance.

The MSB7800-ES2F is fully interoperable with NVIDIA Mellanox ConnectX adapters (EDR, FDR, QDR), LinkX cables, and transceivers. It is compliant with IBTA Specification 1.3 and 1.2.1, and supports backward compatibility to Fourteen Data Rate (FDR) technology. The switch integrates with NVIDIA UFM (Unified Fabric Management) for advanced telemetry, AI-powered analytics, and proactive troubleshooting across the entire InfiniBand fabric.

Note: Verify airflow direction (P2C or C2P) matches your data center hot/cold aisle configuration before ordering.

• Industry-leading performance – 7.2Tb/s throughput and ultra-low latency in a compact 1U chassis.
• Reduced IT costs – Low power consumption (122W ATIS) and simplified management reduce operational expenses.
• Self-healing networking – InfiniBand fabric recovers from link failures 5,000× faster than software-based solutions.
• Flexible deployment – Backward compatible with FDR; supports modern topologies like Dragonfly+, SlimFly, and 6D torus.
• Enhanced telemetry – With UFM, gain real-time network insights and AI-driven analytics for proactive maintenance.
