Mellanox Technologies MSN2700-CS2FO 32-port 100GbE network switch

What this switch is and who it is for

The Mellanox MSN2700-CS2FO is a 1U open network switch built on the Spectrum ASIC with 32 QSFP28 ports running at 100GbE. It ships with ONIE so administrators can install Onyx, Cumulus Linux or another NOS that fits their operational model. The unit includes two AC power supplies, a rail kit and front-to-back airflow for standard rack deployments. It targets data-centre teams that need an open, programmable 100GbE fabric without vendor lock-in.

Behaviour under sustained load

The Spectrum ASIC delivers line-rate 100GbE across all 32 ports with consistent latency and no head-of-line blocking under continuous traffic. Dual hot-swap power supplies keep the chassis running during a supply failure, while the front-to-back cooling design maintains thermal stability in dense racks. ONIE-based software flexibility allows operators to choose a NOS that matches their telemetry and automation workflows for long-term operations.

The spec that decides fit

The switch provides exactly 32 QSFP28 ports at 100GbE with no additional uplink or modular expansion slots. Buyers who need more than 32 100GbE ports in a single chassis, or who require integrated uplink ports of a different speed, must look at a different platform. If 32 ports of 100GbE in a 1U open switch matches the topology, this unit satisfies the requirement.
