NVIDIA 920-9N42F-00RI-7C0 | Spectrum-4 64-Port 800G Switch, 51.2Tbps, 2U

Q: What network topologies does the SN5600 support?
A: The SN5600 is designed for spine, super-spine, and leaf deployments in modern data center fabrics. It supports both standard leaf/spine architectures with top-of-rack switches and end-of-row or middle-of-row topologies, making it ideal for large-scale CLOS networks and AI infrastructure.

Q: Can the 800GbE ports be broken out to lower speeds?
A: Yes, each OSFP port supports flexible breakout configurations. You can split ports to 2x400GbE, 4x200GbE, or 8x100GbE, enabling up to 256 ports of 100GbE connectivity. The switch supports multi-speed Ethernet from 1GbE up to 800GbE per port.

Q: What operating systems are compatible with this switch?
A: This SKU ships with Cumulus Linux authentication. The SN5600 platform also supports SONiC (Software for Open Networking in the Cloud), providing flexibility for open networking deployments and integration with existing network automation tools.

Q: Is this switch optimized for AI and HPC workloads?
A: Yes, the SN5600 is purpose-built for AI, machine learning, and high-performance computing environments. It features accelerated RoCE for GPU-to-GPU communication, consistent sub-microsecond latency, and a fully shared packet buffer to handle bursty AI traffic efficiently. It is a key component of NVIDIA Spectrum-X networking platforms.

Q: What is the difference between C2P and P2C airflow?
A: C2P (Connector-to-Power) airflow means air flows from the front panel where network cables connect toward the rear where power supplies are located. This configuration is designed to match specific data center hot-aisle/cold-aisle layouts. Ensure your airflow direction matches your rack cooling design.
