What is the switching capacity of the MSN3700-CS2R?

The MSN3700-CS2R provides 6.4Tbps full-duplex switching capacity with 32 QSFP28 ports at 100GbE. Powered by Spectrum-2 ASIC, it achieves 8.33Bpps forwarding performance, enabling non-blocking wire-speed across all ports for spine deployments.

Can the ports be split for higher density?

Yes, all 32 QSFP28 ports are fully splittable to up to 128x 10/25GbE using breakout cables, ideal for high-density leaf connectivity while maintaining 100GbE uplinks for spine-to-spine links.

What management software is included?

Ships with NVIDIA Onyx OS for L2/L3 managed switching, supporting advanced features like VXLAN, EVPN, and RoCE. Open variants available with Cumulus Linux or ONIE for network OS flexibility.

What airflow and power configuration does it have?

C2P (connector-to-port) airflow in standard 1U depth with dual redundant AC power supplies. Includes rail kit for rack mounting and x86 CPU for onboard management.

Is it suitable for storage fabrics?

Yes, Spectrum-2 supports RDMA over Converged Ethernet (RoCEv2) with lossless fabric capabilities, perfect for NVMe-oF, Ceph, and GPU-direct storage in AI/HPC environments.

What are the physical dimensions and form factor?

1RU (1U) rack-mountable with standard depth, 32 QSFP28 front ports, rear-to-front C2P airflow, and hot-swappable PSUs for high availability in data centers.
