Description

The NVIDIA MSN3700-CS2FC is a high-performance 1U data center switch built on the Spectrum-2 ASIC, delivering 32 ports of 100GbE QSFP28 connectivity with full port breakout capability to 128x 10/25GbE. With 6.4 Tbps switching capacity, 4.76 Bpps forwarding rate, and sub-microsecond latency, it excels in spine and high-density leaf deployments for cloud-scale networks. Ships with Cumulus Linux preinstalled and features power-to-connector (P2C) airflow, dual AC power supplies, and an x86 management CPU.

Features

FAQs

Q: Can this switch be used as a leaf switch in addition to spine?
A: Yes, the MSN3700-CS2FC is designed for both spine and high-density leaf deployments. Each QSFP28 port supports breakout to 4x25GbE or 4x10GbE, enabling up to 128 logical ports for high-density server aggregation.

Q: What is P2C airflow and why does it matter?
A: P2C (power-to-connector) airflow means air flows from the back (power side) to the front (connector side). This is critical for rack cooling design and must match your data center's hot/cold aisle architecture for proper thermal management.

Q: What network operating system does this switch run?
A: This model ships with Cumulus Linux preinstalled, an open network operating system designed for automation, programmability, and web-scale data center operations using Linux tools and workflows.

Q: What is the difference between the MSN3700-CS2FC and other MSN3700 variants?
A: The MSN3700-CS2FC variant includes Cumulus Linux (indicated by the C suffix) and P2C airflow (F). Other variants may use ONIE or Onyx OS, C2P reverse airflow (R), or secured-boot configurations depending on the suffix.

Q: Can I use this switch for 40GbE connectivity?
A: Yes, all 32 QSFP28 ports support both 100GbE and 40GbE operation, providing backward compatibility with 40GbE infrastructure while offering a migration path to 100GbE.
