About the Mellanox MSN4700-CS2F Spectrum-3 400GbE Ethernet Switch, 32 Ports
L2/L3 switching capabilities—BGP, OSPF, ECMP, VXLAN routing, and EVPN support—determine this switch's role as a high-performance fabric spine or leaf in modern data center architectures. The Mellanox MSN4700-CS2F Spectrum-3 400GbE Ethernet Switch delivers enterprise-grade switching with 32 ports of 400GbE throughput, enabling network engineers and AI infrastructure teams to build ultra-low-latency, high-bandwidth interconnect fabrics at scale. Built on the NVIDIA Spectrum-3 ASIC architecture, this 1U rack-mount switch combines raw performance with intelligent congestion management and real-time diagnostics—essential for demanding workloads including AI training, HPC clusters, and distributed storage environments.
With a total switching capacity of 12.8 Tbps and forwarding rate up to 9.52 Bpps, the MSN4700-CS2F (part number MSN4700-CS2F) provides the throughput density required for hyperscale deployments. Mellanox hardware-enforced lossless RoCE v1/v2 with Explicit Congestion Notification (ECN) and Priority Flow Control (PFC) ensures reliable RDMA performance for storage and compute clustering. The switch supports flexible breakout configurations—4x100GbE, 4x25GbE, or 2x200GbE per port via breakout cables and adapters—maximizing port versatility across heterogeneous infrastructure. Dual redundant hot-swappable power supplies and fan modules guarantee carrier-grade availability, while in-band network telemetry, per-flow counters, and What Just Happened (WJH) diagnostics enable proactive network visibility and rapid troubleshooting.
