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

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)
