NVIDIA Spectrum SN2700-CS2FC 100GbE Open Networking Switch

1. MSN2700 - CS2FC Product Overview

The NVIDIA Spectrum SN2700-CS2FC is a high-performance, 32-port 100GbE open networking switch designed for modern data center leaf, spine, and super-spine deployments. Built on the NVIDIA Spectrum ASIC, this 1RU switch delivers 3.2Tb/s throughput and 4.76 billion packets per second (Bpps) with consistent ultra-low latency of 300ns. It supports a fully shared 16MB packet buffer, dynamic port splitting, and a range of software options including Cumulus Linux, Onyx, and ONIE for maximum flexibility and control.

2. MSN2700 - CS2FC Key Characteristics

• 32 x QSFP28 ports supporting 1/10/25/40/50/100GbE speeds
• 3.2Tb/s throughput and 4.76Bpps processing capacity
• 300ns cut-through latency
• 16MB fully shared dynamic packet buffer
• Dual hot-swappable power supplies and N+1 redundant fans
• Support for Cumulus Linux, Onyx, and ONIE-based network operating systems
• Hardware-accelerated telemetry with WJH (What Just Happened?) technology

3. MSN2700 - CS2FC Core Technologies

The SN2700-CS2FC leverages the NVIDIA Spectrum ASIC with support for advanced data center protocols including VXLAN routing, IPv6 segment routing, RoCE (RDMA over Converged Ethernet), and EVPN. It features a programmable pipeline, deep packet inspection (up to 512B), and hardware-accelerated telemetry for real-time network visibility and analytics.

4. MSN2700 - CS2FC Operational Principle

The switch operates in cut-through mode, minimizing latency by forwarding packets immediately after the destination address is identified. The fully shared buffer architecture dynamically allocates memory to congested ports, preventing packet loss and ensuring fair bandwidth distribution. Hardware-based telemetry collects granular data on queue depth, latency, and packet drops, enabling rapid troubleshooting and performance optimization.

5.MSN2700 - CS2FC  Applications & Usage

Ideal for high-performance computing (HPC), artificial intelligence/machine learning (AI/ML), cloud infrastructure, and storage networks. Commonly deployed as:

• Top-of-Rack (ToR) leaf switch in hyper-scale data centers
• Spine or super-spine switch in Clos network architectures
• High-speed interconnect for GPU-driven workloads and RDMA applications
• Open networking platform for software-defined data centers (SDDC)
