Mellanox MSN2700-CB2F 100GbE 32-Port QSFP28 Switch

Brand:

The Mellanox MSN2700-CB2F is a high-density 100GbE Ethernet switch designed for modern data centers requiring ultra-low latency and scalable fabric architecture. Built for cloud, enterprise, and HPC environments, it supports 32x QSFP28 ports with flexible breakout and high-efficiency airflow design.

OVERVIEW

  • The NVIDIA Mellanox MSN2700-CB2F is a compact yet powerful 100GbE Ethernet switch built on the Spectrum switching architecture, designed for next-generation data center fabrics. It delivers high-density 32x QSFP28 port connectivity, enabling scalable leaf-spine deployments for cloud providers, enterprises, and HPC clusters.
  • Positioned within the high-performance switching portfolio originally developed by Mellanox Technologies, this model supports flexible breakout configurations for 100G, 50G, 40G, and 25G environments, making it ideal for mixed-speed modernization projects.
  • With dual AC power supplies, P2C airflow, and energy-efficient ~150W typical consumption, it supports resilient deployments in dense racks where thermal stability and uptime are critical. Its versatility makes it suitable for enterprise IT teams modernizing legacy networks, cloud architects building scalable fabrics, and HPC operators requiring predictable low-latency performance.
  • Key differentiators include its high port density in a 1U form factor, broad optical and DAC compatibility, and flexible breakout support that reduces infrastructure fragmentation while improving long-term upgrade economics.
