Mellanox MSN2700-CS2R 32x100GbE QSFP28 Spectrum Switch

Brand:

Enterprise 32-port 100GbE Mellanox Spectrum switch designed for data center leaf-spine architectures, cloud networking, and high-throughput fabric deployments. Offers efficient 150W power profile, flexible QSFP28 connectivity, and optimized scalability for modern infrastructures. Designed for scalable cloud and enterprise networks requiring low-latency switching and simplified operations.

OVERVIEW

  • The Mellanox MSN2700-CS2R is a high-density 32-port 100GbE QSFP28 switch built on the NVIDIA Spectrum switching architecture from NVIDIA. It is designed to deliver deterministic, low-latency packet forwarding for modern data center fabrics, supporting leaf-spine, cloud, and high-performance enterprise networking environments.
  • This model is widely used in infrastructure modernization projects where scalable 100G connectivity is required for virtualization, cloud interconnects, and east-west traffic optimization. Its compact 1U design and 150W typical power consumption make it suitable for energy-efficient deployments without compromising throughput density.
  • Key differentiators within its class include its 32x100GbE QSFP28 port density, flexible optical and DAC support for varied connectivity models, and optimized airflow (C2P) suited for structured rack deployments. It is positioned for enterprises seeking predictable scaling, simplified fabric design, and long lifecycle networking investment.
