High Light NVIDIA InfiniBand Smart Switch 36 QSFP28 ports ，100Gb/s InfiniBand Switch MLNX-OS managed ，7.2Tb/s network switch with 36 ports
NVIDIA MSB7800-ES2F 100Gb/s InfiniBand Smart Switch
High-performance fixed-configuration 100Gb/s InfiniBand smart switch delivering 36 QSFP28 ports with non‑blocking 7.2 Tb/s bidirectional throughput and ultra‑low port latency. Purpose‑built for top‑of‑rack leaf connectivity in HPC, AI training clusters, and enterprise data centers.
Key Specifications
  • Ports: 36 x QSFP28 (100Gb/s)
  • Throughput: 7.2 Tb/s non‑blocking
  • Latency: ~90ns port‑to‑port
  • Power (Typ.): 122W (ATIS weighted)
  • Airflow: P2C (Port‑to‑Core) / Front‑to‑Rear
  • Management: MLNX‑OS (internal) + UFM ready
Product Overview
The NVIDIA MSB7800‑ES2F is a 100Gb/s InfiniBand fixed switch from the SB7800 series, engineered for environments where every bit of bandwidth and ultra‑low latency matter. It packs 36 ports of 100Gb/s into a compact 1U chassis, delivering an aggregate bidirectional throughput of 7.2 Tb/s.
This model features P2C (port‑to‑core) airflow — ideal for data center cold‑aisle cooling designs with front‑to‑rear airflow. The onboard Intel Celeron dual‑core x86 CPU with 4GB DDR3 RAM and 16GB SSD runs MLNX‑OS, enabling comprehensive chassis management, CLI/WebUI, and automation.
Key Features
  • 36 x 100Gb/s QSFP28 ports - Full bidirectional non‑blocking bandwidth with EDR InfiniBand support
  • 7.2 Tb/s aggregate throughput - High‑density switching capacity in a 1U form factor
  • In‑Network Computing with SHARP™ - Offloads collective operations from CPU to switch fabric
  • Fully managed with MLNX‑OS - Onboard dual‑core x86 CPU, supports CLI, WebUI, SNMP, and JSON APIs
  • Redundant & hot‑swappable components - 1+1 redundant power supplies and hot‑swappable fan modules
  • Energy‑efficient design - ATIS weighted power consumption as low as 122W
  • P2C airflow (MSB7800‑ES2F) - Front‑to‑rear cooling compatible with standard data center layouts
  • NVIDIA UFM® ready - Integration with Unified Fabric Manager for advanced telemetry and automation
Technology: In-Network Acceleration with SHARP
NVIDIA Scalable Hierarchical Aggregation and Reduction Protocol (SHARP)™ improves MPI operation performance by offloading collective communication operations from the CPU to the switch network. This dramatically reduces MPI operation time and decreases total data traversing the network.
For AI and deep learning workloads, SHARP accelerates NCCL collective operations, delivering up to 2.5x performance improvement. The MSB7800 series includes dedicated hardware support for SHARP, making it a key enabler for large‑scale distributed training and scientific computing.

Frequently Asked Questions
What is the difference between MSB7800 and MSB7880?
MSB7800 is a standard InfiniBand switch for leaf/spine fabrics. MSB7880 is an InfiniBand router that provides gateway functionality, enabling connectivity between independent subnets with isolation and multi‑tenant capabilities.
Does it support SHARP™ technology?
Yes. The MSB7800 series fully supports NVIDIA SHARP in‑network computing for collective operation acceleration across the fabric.
What management options are available?
MLNX‑OS provides CLI, WebUI, SNMP, and JSON APIs. For larger deployments, the switch can be managed by NVIDIA UFM for advanced telemetry, predictive analytics, and automation.
Precautions & Ordering Notes
  • Airflow direction is critical: MSB7800‑ES2F uses P2C (port‑to‑core) airflow — verify rack cooling design
  • Power input: Dual redundant AC with C13/C14 connectors (100‑240VAC)
  • Rack depth: Standard depth 27 in — verify rack compatibility
  • Cables and transceivers sold separately — plan QSFP28 cabling based on distance requirements
Buyer Checklist
  • Confirm airflow direction: MSB7800-ES2F uses P2C — verify rack cooling compatibility
  • Verify cable type: QSFP28 DAC or optical transceivers based on distance
  • Check power input: dual redundant AC with C13/C14 connectors (100‑240VAC)
  • Ensure rack depth supports 27 inches — standard depth
  • Plan for management: MLNX‑OS provides on‑board management; UFM optional for larger fabrics
  • Validate SHARP™ support in your application stack
  • Confirm warranty and support options
