NVIDIA 920-9N301-00RB-0C0 | Spectrum-3 32-Port 400GbE Switch, 12.8Tb/s, C2P Airflow

Q: What deployment scenarios is the MSN4700-WS2RC best suited for?
A: This switch is purpose-built for spine and super-spine roles in large-scale data center fabrics, including hyperscale cloud environments, AI/ML training clusters, high-performance storage networks, and GPU Direct RDMA deployments requiring ultra-low latency and high throughput.

Q: Can this switch support mixed port speeds in the same deployment?
A: Yes, the Spectrum-3 ASIC supports flexible port breakout and mixed speeds from 1GbE to 400GbE across all 32 QSFP-DD ports, allowing you to connect endpoints at varying speeds within the same fabric without performance degradation.

Q: What network operating systems are compatible with this model?
A: The MSN4700-WS2RC ships with Cumulus Linux pre-installed. The underlying Spectrum-3 hardware also supports NVIDIA Onyx, SONiC, and ONIE-based operating systems, providing flexibility for different network automation and orchestration requirements.

Q: Does this switch support RoCE for storage and AI workloads?
A: Yes, the Spectrum-3 ASIC includes hardware support for RDMA over Converged Ethernet (RoCE), making it suitable for NVMe-oF storage fabrics, GPU Direct RDMA, and other latency-sensitive AI/ML distributed training applications.

Q: What advanced telemetry and monitoring features are available?
A: The switch supports Inband Network Telemetry (INT), What Just Happened (WJH) telemetry, streaming telemetry, and deep packet inspection up to 512 bytes, providing real-time visibility into network performance, congestion points, and packet drops for proactive troubleshooting.
