The NVIDIA Mellanox MSN2700-CS2F is a high-performance 100GbE Ethernet switch purpose-built for modern data center architectures. Powered by the Spectrum ASIC, this 1U switch delivers 6.4Tbps aggregate switching capacity with 32 QSFP28 ports supporting speeds from 10Gbps to 100Gbps per port. The switch achieves 9.52 billion packets-per-second throughput with ultra-low 300 nanosecond latency, enabling wire-speed forwarding at all packet sizes. Running Mellanox Onyx (MLNX-OS) or ONIE-compatible operating systems, it supports comprehensive routing protocols (BGP-4, OSPFv2, VRRP) and advanced data center features including VLAN (4000 VLANs), ACLs, LACP, LLDP, RSTP, MSTP, and Priority-Based Flow Control. With dual AC power supplies consuming only 235W operational power and front-to-back airflow cooling, the MSN2700-CS2F is ideal for spine and top-of-rack (ToR) deployments in hyperscale data centers, cloud infrastructure, and high-performance computing environments requiring maximum port density and predictable low-latency performance.

Frequently asked questions
What is the switching capacity and latency of the MSN2700-CS2F?
The MSN2700-CS2F delivers 6.4Tbps aggregate switching capacity with 9.52 billion packets-per-second throughput and ultra-low 300 nanosecond latency. This non-blocking architecture ensures wire-speed forwarding across all 32 ports simultaneously at all packet sizes, making it ideal for latency-sensitive applications like HPC and real-time trading.
What port types and speeds does this switch support?
The switch features 32 QSFP28 ports supporting flexible speeds from 10Gbps to 100Gbps per port. Each port can be configured independently for 10/25/40/50/56/100GbE operation, enabling mixed-speed deployments. QSFP28 optics support both copper and fiber connectivity with standard MSA-compliant transceivers.
Which operating systems can run on the MSN2700-CS2F?
The switch ships with Mellanox Onyx (MLNX-OS), a purpose-built Linux-based network operating system optimized for Spectrum hardware. It also supports ONIE (Open Network Install Environment), allowing installation of alternative NOS platforms like Cumulus Linux, Big Switch Networks, or vendor-specific distributions for maximum flexibility.
What advanced networking features are included?

Is this switch suitable for top-of-rack (ToR) and spine deployments?
Yes, the MSN2700-CS2F is explicitly designed for both ToR and spine roles. Its flexible port speeds enable direct server connectivity at mixed rates, while the 6.4Tbps capacity and low latency make it ideal for spine aggregation. The 1U form factor and standard-depth design fit any data center rack, and the modular architecture scales from single switches to thousands of nodes.
What power and cooling specifications should I plan for?
The switch includes dual AC power supplies (120/230V input) with 235W typical operational power consumption. It uses front-to-back (P2C) airflow cooling, requiring standard data center cooling infrastructure.
