Silver 1U rack switch with sixteen QSFP28 ports and dual power supplies

Mellanox Technologies

Mellanox Technologies MSN2100-CB2F 16-port 100GbE network switch

SKU CH-5P2G-C2TVZ MPN MSN2100-CB2F

A half-width 1U switch delivers 16 non-blocking 100GbE QSFP28 ports with 3.2Tb/s throughput and 2.38Bpps capacity for spine or top-of-rack deployments

  • 16 QSFP28 ports deliver 100GbE density for spine or top-of-rack deployments
  • 2Tb/s non-blocking throughput handles database and storage traffic at line rate
  • 38Bpps processing capacity sustains high packet rates in compact 1U form
  • Dual AC power supplies provide redundancy for continuous data-centre operation
  • Port speeds from 10Gb/s to 100Gb/s enable flexible rack connectivity at any speed

Switch overview

The Mellanox MSN2100-CB2F is a 1U open Ethernet switch with 16 QSFP28 ports running at 100GbE. It delivers 3.2Tb/s throughput and 2.38Bpps processing capacity in a half-width chassis. The system includes two AC power supplies and uses port-to-cold airflow. It suits data centres that need dense, non-blocking 100GbE connectivity.

Who it suits

This switch fits spine or top-of-rack roles where 16 ports of 100GbE provide full rack connectivity at any speed from 10Gb/s to 100Gb/s per port. Buyers who need more than 16 ports in a single appliance should look at a larger system. Teams that require a fixed proprietary OS instead of an open Ethernet platform should consider a different product line.

Deciding specification

The switch provides exactly 16 QSFP28 ports operating at 100GbE with a combined throughput of 3.2Tb/s. If your design calls for 16 ports of 100GbE in 1RU, this unit matches the requirement. If the port count or aggregate bandwidth must be higher, this model will not meet the need.

Questions about this item

How do I verify the switch is delivering the full 3.2 Tb/s throughput after setup?

Monitor the management interface for port counters showing line-rate traffic across all 16 QSFP28 ports and confirm the forwarding engine reports 2.38 Bpps processing capacity under load.

What ships with the MSN2100-CB2F and what must I source separately?

The unit includes two AC power supplies and the x86 dual-core management module; you must purchase QSFP28 transceivers and compatible cables for each of the 16 ports you intend to use.

Which port-speed configuration should I choose for a 128-port spine build?

Use all 16 ports at 100 GbE on each MSN2100-CB2F and interconnect up to eight switches to reach the 128-port non-blocking fabric limit.
