Product Description
NVIDIA Spectrum SN2000 Series MSN2201-CB2FC: High-Density 1GbE/100GbE Open Networking Switch
The NVIDIA Spectrum SN2000 Series MSN2201-CB2FC is a high-performance, open Ethernet switch designed for modern data center top-of-rack (ToR) and out-of-band management applications. It combines 48 x 1GbE RJ45 ports with 4 x 100GbE QSFP28 uplinks in a 1U form factor, delivering 448Gb/s throughput and advanced features like hardware telemetry, RoCE support, and cloud-scale automation. Ideal for enterprise, cloud, and storage environments, this network switch offers flexibility, low latency, and vendor-agnostic operation.
Key Features
- 48 x 1GbE RJ45 + 4 x 100GbE QSFP28 ports
- 448Gb/s throughput, 667Mpps forwarding rate
- 300ns cut-through latency
- 16MB fully shared packet buffer
- Hardware-accelerated telemetry (WJH, INT)
- Dual hot-swappable power supplies (AC)
- Pre-installed with Cumulus Linux or ONIE option
Technology
The SN2000 series is powered by the NVIDIA Spectrum ASIC, supporting advanced features like VXLAN routing, RoCE (RDMA over Converged Ethernet), hardware-level telemetry, and programmable pipelines. It complies with IEEE Ethernet standards and supports open networking initiatives like ONIE for OS flexibility.
Working Principle
The switch operates with a fully shared packet buffer architecture, dynamically allocating resources to congested ports to prevent packet loss. It supports cut-through switching for low latency and features a deep packet inspection capability up to 512 bytes. The hardware-based telemetry engine provides real-time visibility into network performance and issues.
Applications
- Data Center Top-of-Rack (ToR) Leaf Switching
- Out-of-Band (OOB) Management Networks
- Hyper-Converged Infrastructure (HCI)
- Cloud and Enterprise Storage Fabrics
- High-Performance Computing (HPC) and AI Clusters

FAQ
Q: Can I run SONiC on this SN2000 series switch?
A: Yes, the SN2201 supports SONiC via ONIE installation, along with Cumulus Linux and other ONIE-compatible NOS options.
Q: What is the typical power consumption?
A: Approximately 100W under typical load conditions.
Q: Does it support breakout cables for the 100GbE ports?
A: Yes, the QSFP28 ports can be split into 4x25GbE or 2x50GbE using compatible DAC or AOC cables.
Q: Is the airflow direction configurable?
A: Yes, reversible airflow (P2C or C2P) is supported with appropriate fan and PSU modules.
Precautions
- Ensure compatible transceivers and cables are used as per NVIDIA specifications.
- Operating temperature: 0°C to 40°C with 5% to 85% relative humidity.
- Verify airflow direction (P2C or C2P) matches data center cooling design.
- Use ESD protection during installation and handling.
- Follow local electrical and safety standards during installation.
