MSN2100-CB2F: High-Density 100GbE Data Center Switch

The MSN2100-CB2F is a high-performance network switch from NVIDIA's Spectrum SN2000 Series, engineered for modern data center deployments. This 1U form factor switch delivers 1.6Tb/s throughput with 16×100GbE QSFP28 ports, offering exceptional flexibility and low-latency performance. Designed for leaf, spine, and super-spine applications, this SN2000 series switch supports multiple open networking operating systems, providing unparalleled control and visibility into data center operations.

Key Characteristics

• 16×100GbE QSFP28 ports supporting 10/25/40/50/100GbE speeds
• 1.6Tb/s switching capacity with 2.38 billion packets per second forwarding rate
• Consistent 300ns cut-through latency across all packet sizes
• 16MB fully shared, dynamically allocated packet buffer
• Dual hot-swappable power supplies with 1+1 redundancy
• Support for Cumulus Linux, ONYX, SONiC, and ONIE-compatible operating systems

Advanced Technologies

The MSN2100-CB2F leverages NVIDIA's Spectrum ASIC technology with several innovative features:

• Hardware-accelerated RoCE (RDMA over Converged Ethernet) for GPU-direct workloads
• VXLAN routing and bridging with 6× greater tunnel capacity than alternatives
• In-band Network Telemetry (INT) and streaming telemetry capabilities
• Deep packet inspection up to 512 bytes for advanced monitoring
• Programmable pipeline for custom networking functions
• Open Ethernet architecture eliminating vendor lock-in

Operational Principle

This network switch operates in cut-through mode, forwarding packets immediately upon reading the destination address without storing entire frames. The Spectrum ASIC employs a fully shared packet buffer architecture that dynamically allocates memory to congested ports, preventing packet loss during traffic bursts. Hardware-based telemetry collects real-time data on network performance, queue depths, and events through the What Just Happened? (WJH) feature, providing unprecedented visibility into network operations.

Application Scenarios

The MSN2100-CB2F SN2000 switch is ideally suited for:

• Cloud data centers and hyperscale environments
• AI/ML clusters and high-performance computing
• Hyperconverged infrastructure and storage networks
• Financial trading platforms requiring ultra-low latency
• Enterprise data center spine and leaf deployments
• High-frequency trading environments
