Spectrum-2 delivers 6.4 Tb/s throughput (12.8 Tb/s full duplex) and 8.33 Bpps packet processing, with a 42 MB fully shared on-chip packet buffer and consistent low cut-through latency of 425 ns.
Built for AI, Storage and Cloud Fabrics
RoCE transport for NVMe over Fabrics and GPUDirect workloads, single-pass VXLAN routing, IPv6 segment routing, up to 512K shared forwarding entries and NVIDIA What Just Happened (WJH) telemetry for fast root-cause analysis.
Cumulus Linux Pre-Installed
This MSN3700-VS2FC model ships with NVIDIA Cumulus Linux, with dual hot-swap AC power supplies (1+1), six hot-swap fans (N+1), port-to-cable (P2C) airflow and a rail kit.

Frequently Asked Questions — NVIDIA SN3700 (MSN3700-VS2FC)
Which operating system does the MSN3700-VS2FC run?
NVIDIA Cumulus Linux, pre-installed. The Onyx version is MSN3700-VS2F and the ONIE version is MSN3700-VS2FO.
Can the 200GbE ports be split?
Yes. The 32 QSFP56 ports support 64 x 100GbE or up to 128 x 1/10/25/50GbE with breakout cables.
What does P2C airflow mean?
Air enters at the port side and exits at the power-supply side. Choose the C2P model (MSN3700-VS2RC) if your rack needs the reverse direction.
Are transceivers or cables included?
No. QSFP56 optics and DAC/AOC cables are sold separately.
What warranty do I get?
1 Year limited hardware return-and-repair warranty, supplied by SourceIT with a GST invoice.
