NVIDIA Mellanox MSB7800-ES2F 100G InfiniBand Switch 36-Port 7.2Tb/s Managed Switch with P2C Airflow

The NVIDIA Mellanox MSB7800‑ES2F is a high‑performance 100Gb/s InfiniBand smart switch designed to meet the demanding requirements of modern HPC, AI, and cloud data centers. Part of the NVIDIA SB7800 series, this switch delivers 36 QSFP28 ports operating at 100Gb/s per port, with an aggregate non‑blocking throughput of 7.2 Tb/s and ultra‑low port latency. Built on the proven InfiniBand architecture, the MSB7800‑ES2F provides the ideal top‑of‑rack leaf connectivity solution for small to extremely large clusters.

The switch features a fully managed architecture with an onboard dual‑core x86 CPU running MLNX‑OS®, enabling comprehensive chassis management of firmware, power supplies, fans, and ports. With support for NVIDIA SHARP™ in‑network computing technology, the MSB7800‑ES2F offloads collective operations from CPUs to the network fabric, dramatically accelerating MPI and deep learning workloads. The MSB7800‑ES2F variant features P2C (port‑to‑power) airflow, making it suitable for data center cooling architectures where cold air is supplied from the port side.

• 100Gb/s InfiniBand per port – 36 QSFP28 ports delivering full bidirectional bandwidth with non‑blocking architecture.
• 7.2 Tb/s Aggregate Throughput – High‑density switching capacity in a compact 1U form factor.
• In‑Network Computing Acceleration – NVIDIA SHARP™ technology offloads collective operations from CPUs to the switch fabric, reducing MPI operation time and freeing valuable CPU resources for computation.
• Fully Managed with MLNX‑OS – Onboard dual‑core x86 CPU (Intel Celeron 1047UE) with 4GB RAM and 16GB SSD provides comprehensive management via CLI, WebUI, SNMP, and JSON interfaces.
• Redundant & Hot‑Swappable Components – 1+1 redundant power supplies with 80 Plus Gold certification, plus hot‑swappable fan modules for maximum availability.
• Energy Efficient Design – ATIS weighted power consumption as low as 122W for a fully populated system; dynamic power scaling reduces consumption when ports are not fully utilized.
• Flexible Cooling Options – P2C (port‑to‑power) airflow configuration (MSB7800-ES2F) with front‑to‑rear cooling.
• UFM Ready – Can be integrated with NVIDIA Unified Fabric Manager (UFM) for advanced telemetry, predictive analytics, and automated fabric orchestration.

High‑performance computing and AI workloads demand intelligent interconnect solutions to achieve maximum application performance. NVIDIA SHARP™ (Scalable Hierarchical Aggregation and Reduction Protocol) technology is embedded directly in the switch silicon, enabling in‑network computing that offloads collective operations from the CPU to the switch network. This innovative approach eliminates the need to send data multiple times between endpoints, dramatically reducing MPI operations time and decreasing the amount of data traversing the network.

By accelerating collective communications such as all‑reduce, barrier, and broadcast, SHARP™ technology delivers order‑of‑magnitude performance improvements for deep learning frameworks (NCCL, TensorFlow, PyTorch) and traditional HPC applications. Additional benefits include freeing up valuable CPU resources for computation rather than consuming them for communication processing, resulting in higher overall application throughput.

• Top‑of‑Rack (ToR) Leaf Connectivity – Ideal for connecting compute nodes in small to extremely large clusters, providing high‑density 100Gb/s access layer switching.
• AI & Machine Learning Clusters – GPU‑based systems requiring high‑bandwidth, low‑latency interconnect with SHARP™ acceleration for NCCL collective operations.
• High‑Performance Computing (HPC) – Research labs, universities, and enterprise HPC environments running MPI‑based simulations and modeling workloads.
• Enterprise Data Centers – Storage and compute fabrics requiring reliable, high‑performance InfiniBand connectivity.
• Cloud & Hyperscale Infrastructure – Scalable fabric deployments supporting fat tree, DragonFly+, and other advanced topologies.

The MSB7800‑ES2F works seamlessly with NVIDIA ConnectX‑5, ConnectX‑6, and ConnectX‑7 InfiniBand adapters, as well as BlueField DPU families. It is backward compatible with previous InfiniBand speeds (EDR, FDR, QDR), ensuring investment protection and smooth migration paths. Fully interoperable with other NVIDIA SB7800 and Quantum series switches, and can be managed via MLNX‑OS or integrated with NVIDIA UFM for centralized fabric management. Operating system support includes all major Linux distributions (RHEL, Ubuntu, Rocky Linux, SuSE) and Windows Server with InfiniBand stack.

For top‑of‑rack leaf connectivity in data centers with front‑to‑rear cooling, MSB7800‑ES2F (P2C airflow) is the ideal choice. For rear‑to‑front cooling designs, select MSB7800‑ES2R. Router variants (MSB7880) add gateway functionality for multi‑subnet fabrics.

• Superior ROI – High port density in 1U reduces switch count and cabling complexity, lowering capital expenditure.
• Energy Efficient – Industry‑leading power efficiency (122W typical) with ATIS weighted measurement; dynamic power scaling reduces operational costs.
• SHARP™ Acceleration – Up to 10x faster collective communications without consuming host CPU cycles, maximizing compute utilization.
• Simplified Management – MLNX‑OS provides comprehensive out‑of‑the‑box management with CLI, WebUI, and APIs.
• Reduced IT Complexity – Single switch model scales from small clusters to extremely large deployments with consistent management.
• Proven Ecosystem – Backed by NVIDIA cumulative software stack and global partner support.
• Investment Protection – Backward compatible with previous InfiniBand generations, protecting existing infrastructure investments.
