NVIDIA Spectrum SN2000 Series MSN2201-CB2RC: High-Density 1GbE/100GbE Open Networking Switch
The NVIDIA Spectrum SN2000 Series MSN2201-CB2RC represents a versatile open networking solution, combining 48 x 1GbE copper ports with 4 x 100GbE QSFP28 uplinks in a compact 1U form factor. This advanced network switch delivers 448Gb/s throughput with consistent 300ns latency, making it ideal for both top-of-rack deployments and out-of-band management applications. Engineered with the NVIDIA Spectrum ASIC, it supports comprehensive Layer 2/3 features, RoCE acceleration, and hardware-level telemetry for unparalleled visibility in modern data center environments.
Key Characteristics
- 48 x 1GbE RJ45 ports + 4 x 100GbE QSFP28 uplink ports
- 448Gb/s switching capacity with 667Mpps forwarding rate
- 300ns cut-through latency for performance-sensitive applications
- 16MB dynamically shared packet buffer prevents congestion
- Hardware-accelerated telemetry with WJH® (What Just Happened) technology
- Dual hot-swappable power supplies with N+1 fan redundancy
- Pre-loaded with Cumulus Linux for open networking flexibility
- C2P (Port-to-PSU) airflow configuration for optimized cooling
Core Technology
The MSN2201-CB2RC leverages NVIDIA's Spectrum ASIC technology, delivering advanced features including VXLAN routing, EVPN support, and RoCE (RDMA over Converged Ethernet) optimization. This network switch complies with IEEE Ethernet standards and supports open networking frameworks including ONIE for operating system flexibility. The architecture incorporates a programmable pipeline with deep packet inspection capability up to 512 bytes for enhanced security and traffic analysis.
Operational Principle
This SN2000 series switch employs a cut-through switching architecture that begins forwarding packets before fully receiving them, minimizing latency to 300ns. The fully shared 16MB packet buffer dynamically allocates resources to congested ports, preventing packet loss during traffic bursts. Hardware-accelerated telemetry monitors queue depths at sub-microsecond granularity, providing unprecedented visibility into network performance and issues.
Application Scenarios
- Data Center Top-of-Rack (ToR) switching for server connectivity
- Out-of-Band (OOB) management network infrastructure
- Hyper-Converged Infrastructure (HCI) and storage networking
- Enterprise campus core and distribution layer switching
- Cloud networking and multi-tenant environments
- High-Performance Computing and AI/ML cluster interconnects

Frequently Asked Questions
Q: What networking operating systems are supported on this SN2000 series switch?
A: The MSN2201-CB2RC supports multiple NOS options including Cumulus Linux (pre-installed), SONiC, and Onyx through the ONIE installation framework.
Q: Can the 100GbE ports be split into lower-speed connections?
A: Yes, the QSFP28 ports can be bifurcated into 4x25GbE or 2x50GbE connections using appropriate breakout cables.
Q: What is the difference between P2C and C2P airflow configurations?
A: P2C (Power-to-Port) airflow moves air from power supplies to ports, while C2P (Port-to-Power) moves air from ports to power supplies. The MSN2201-CB2RC uses C2P airflow.
Q: Does this network switch support RDMA protocols?
A: Yes, the switch hardware provides optimized support for RoCE (RDMA over Converged Ethernet) with congestion management and load balancing.
Q: What type of transceivers and cables are compatible?
A: The switch supports standard QSFP28 transceivers and DAC/AOC cables for 100GbE, 40GbE, and 25GbE connections.
