FAQs

Q: What network operating systems does the NVIDIA SN5400 support?
A: The SN5400 ships with Cumulus Linux pre-loaded and is also SONiC ready, providing open-networking flexibility. It supports NVIDIA's full portfolio of network operating systems for modern data center deployments.

Q: Can the QSFP56-DD ports be broken out to lower speeds?
A: Yes, the SN5400 supports flexible port breakout configurations. Each 400GbE QSFP56-DD port can operate at multiple speeds including 400G, 200G, 100G, 50G, 40G, 25G, and 10GbE. Maximum breakout configurations include up to 256 ports at 100GbE, 50GbE, 25GbE, or 10GbE.

Q: What deployment scenarios is the SN5400 designed for?
A: The SN5400 is optimized for AI infrastructure, GPU cluster fabrics, hyperscale cloud data centers, high-performance storage networks, and modern spine/leaf architectures. It functions effectively as a smart-leaf, spine, or super-spine switch in advanced CLOS topologies with full support for RDMA over Converged Ethernet (RoCE) and advanced VXLAN routing.

Q: What does C2P airflow mean and why does it matter?
A: C2P stands for connector-to-power airflow, meaning air flows from the front port side to the rear power supply side. Airflow direction must match your data center's hot aisle/cold aisle design. The SN5400 is also available in P2C (power-to-connector) airflow configurations for different deployment requirements.

Q: Is this switch compatible with NVIDIA AI and GPU platforms?
A: Yes, the SN5400 is pre-validated with NVIDIA EGXTM, DGX PODTM, OVX SuperPODs, and Spectrum-X AI solutions. It is also tested with NVIDIA BlueField DPUs, ConnectX SmartNICs, and LinkX interconnects, providing end-to-end validated solutions for AI workloads requiring consistent low latency and high throughput.
