About the NVIDIA Spectrum SN1200 - 400GbE
L2/L3 switching with BGP/OSPF routing and VXLAN/EVPN overlay protocols determines your fabric role—and the NVIDIA Spectrum SN1200 - 400GbE (part number SN1200-2S) is purpose-built for high-density, low-latency data center deployments. This 1U fixed configuration switch combines 48 SFP28 (25GbE) downlink ports with 8 QSFP28 (100GbE) uplink ports, delivering 56 total switch ports in a compact footprint. With a switching capacity of 3.2 Tbps and a forwarding rate up to 1.2 Bpps, the SN1200-2S moves traffic at wire speed while maintaining sub-microsecond cut-through latency—critical for time-sensitive workloads in enterprise and service provider networks.
Built on the NVIDIA Spectrum-1 ASIC, this switch supports multiple port speeds (10GbE, 25GbE, 40GbE, 100GbE) to accommodate diverse connectivity needs across your infrastructure. The MAC address table supports 128K entries, while IPv4 routing scales to 128K entries with up to 4K ECMP next-hop groups—enabling efficient traffic distribution and redundancy. VLAN support extends to 4K (802.1Q), and NVIDIA's Cumulus Linux or Onyx operating systems provide open, programmable management. Redundant hot-swap AC power supplies and hot-swappable fan modules with flexible airflow options (front-to-rear or rear-to-front) ensure operational reliability and simplified maintenance. Network engineers and data center architects will appreciate the out-of-band management via dedicated RJ-45 and USB ports, allowing secure, independent device administration.
