MSN3700-VS2FC Overview
A data center switch is the top-of-rack or spine-layer device that interconnects servers, storage, and other switches in a leaf/spine fabric. Within the network equipment hierarchy, the MSN3700-VS2FC belongs to the NVIDIA Spectrum SN3000 series of Open Ethernet switch systems, positioned above 100G access platforms and alongside the modular SN3000 chassis products for cloud-scale deployments.
Key features include 32x QSFP56 ports supporting 1GbE through 400GbE speeds per the SN3000 series datasheet, full 12.8 Tb/s non-blocking fabric for rack-scale connectivity, redundant hot-swappable AC power supplies, and a Cumulus Linux operating environment enabling automation with standard DevOps tooling. The SN3000 series is purpose-built for leaf, spine, and super-spine data center topologies.
The Spectrum-2 ASIC provides flexible port speeds spanning 1GbE to 400GbE, allowing a single platform to serve mixed-speed fabrics. The x86 management CPU runs Cumulus Linux natively, supporting REST APIs, Ansible, and telemetry for cloud-style operations. P2C airflow matches typical forward-flow rack cooling, and the standard-depth chassis fits common 1U racks with the included rail kit.
Typical applications include 200G spine switches in hyperscale and enterprise data centers, VAST Data and high-performance NVMe storage fabric interconnects (the MSN3700-VS2FC is a listed VAST Data OPN), and AI/ML cluster leaf fabrics where 100G/200G server connectivity is required.
Design consideration: exact power consumption figures are not published in the available evidence; confirm AC power budget and PSU redundancy requirements with the manufacturer datasheet before finalizing rack power planning.

Typical Applications
MSN3700-VS2FC is suitable for 6 applications: 200G Data Center Spine Switch, High-Performance NVMe Storage Fabric, AI/ML Cluster Leaf Fabric, Enterprise Data Center Leaf/Spine Upgrade, Super-Spine / Pod Interconnect, Surveillance and IP Security Network Core.
200G Data Center Spine Switch
The MSN3700-VS2FC fits the spine role of leaf/spine fabrics where every leaf downlink must run at line rate: its 32 QSFP56 ports and 12.8 Tb/s non-blocking Spectrum-2 fabric provide full-bandwidth connectivity to up to 32 leaf switches at 200GbE each, per the NVIDIA SN3000 series datasheet. Deployed at the spine layer, each port aggregates multiple 100G leaf uplinks or connects directly to 200G-ready leaf platforms, and the SN3000 series spans 1GbE to 400GbE so migration does not require a hardware refresh. Running Cumulus Linux on the x86 CPU, spine provisioning is automated through standard DevOps tooling, with telemetry for fabric-wide monitoring. Redundant AC PSUs and 1U standard-depth chassis match typical data center spine rack constraints.
Recommended
High-Performance NVMe Storage Fabric
The MSN3700-VS2FC is a listed NVIDIA OPN for VAST Data clusters (VAST SKU ETH-NVMEF-1X32-200G), where storage traffic benefits directly from its 12.8 Tb/s non-blocking fabric and 32x 200GbE QSFP56 ports. In NVMe-oF and disaggregated storage architectures, each storage server or enclosure connects at 100G/200G, and any oversubscription shows up as tail-latency degradation on I/O; the Spectrum-2 ASIC's line-rate forwarding keeps east-west storage traffic predictable. Cumulus Linux on the integrated x86 CPU enables consistent automation with the compute fabric, while dual AC PSUs protect against single-supply failure in storage-critical racks. P2C airflow and the 1U standard-depth form factor fit standard storage racks without special cooling provisions.
Recommended
AI/ML Cluster Leaf Fabric
AI training clusters generate intense east-west traffic during gradient synchronization, and the MSN3700-VS2FC serves as a leaf switch providing 100G/200G server uplinks with 12.8 Tb/s of fabric capacity, minimizing buffer-induced jitter under all-to-all traffic bursts. The SN3000 series supports port speeds from 1GbE to 400GbE per NVIDIA's datasheet, so a single leaf platform accommodates 25G/50G/100G server NICs today and migrates to 200G without replacement. Cumulus Linux exposes standard interfaces for integration with cluster schedulers and telemetry pipelines used in AI infrastructure. Two redundant AC PSUs sustain availability through the multi-day training runs typical of large model workloads, and the 1U chassis maximizes rack compute density.
Recommended
Enterprise Data Center Leaf/Spine Upgrade
Enterprises consolidating legacy 10G/40G networks onto modern 100G/200G fabrics can deploy the MSN3700-VS2FC incrementally: the SN3000 series' 1GbE-to-400GbE port-speed flexibility per the NVIDIA datasheet lets legacy 40G and new 100G/200G links coexist during transition. As a spine, its 32 ports support large multi-pod designs; as a leaf, it connects up to 32 servers or storage systems with headroom for growth. Cumulus Linux brings cloud-style automation (Ansible, REST API) to enterprise operations teams, and the x86 CPU hosts telemetry agents for monitoring integration. The dual-PSU, 1U standard-depth hardware with rail kit installs into existing enterprise racks without infrastructure changes.
Recommended
Super-Spine / Pod Interconnect
The NVIDIA SN3000 series is explicitly positioned for super-spine deployments, and the MSN3700-VS2FC aggregates multiple leaf/spine pods into a two-tier super-spine fabric: each 200GbE QSFP56 port carries pod uplinks while the 12.8 Tb/s Spectrum-2 fabric keeps inter-pod traffic non-blocking. For cloud and large enterprise operators building three-tier topologies, this platform allows 100G pod uplinks today with a path to 200G/400G, since the series spans 1GbE to 400GbE port speeds per the datasheet. Cumulus Linux on the x86 CPU supports the automation scale required at super-spine layers, where hundreds of links are managed programmatically, and redundant hot-swappable AC PSUs meet the high-availability requirements of the network core.
Recommended
Surveillance and IP Security Network Core
Large-scale IP surveillance deployments aggregate hundreds of high-bitrate camera streams; per published reseller information, the MSN3700-VS2FC integrates into NVIDIA's broader Spectrum switch portfolio and supports standard data center network management protocols used in surveillance networks. Its 32x 200GbE QSFP56 ports and 12.8 Tb/s fabric absorb massive many-to-one video traffic toward recording servers without the congestion that causes frame loss, and QSFP56 breakouts accommodate 10G/25G camera-side aggregation switches. Cumulus Linux with the x86 CPU enables segmented, monitored topologies typical of security networks, while dual redundant AC PSUs maintain continuous recording availability. The 1U standard-depth chassis with P2C airflow installs in standard surveillance equipment racks.

Key Differentiators
- Active NVIDIA SKU with long-term support path (vs SSE-SN3700-VS2RC)
- Full 12.8 Tb/s non-blocking fabric in 1U (vs MSN3700-VS2F)
- Cumulus Linux automation out of the box (vs MSN3700-CS2FC)
Design Notes
The MSN3700-VS2FC ships with two redundant hot-swappable AC PSUs; exact power consumption is not published in available evidence, so rack power budgets must be confirmed against the NVIDIA SN3000 series datasheet or NVIDIA pre-sales engineering before deployment. Feed the two PSUs from independent power circuits (A/B feeds) to realize true N+1 redundancy, and verify PDU outlet ratings and branch circuit capacity with margin for peak and inrush conditions.
The VS2FC suffix specifies P2C (port-to-connector) airflow: air enters at the port side and exhausts at the PSU side. Mismatching airflow direction with rack cooling (hot-aisle/cold-aisle arrangement) causes hot-air recirculation and thermal throttling risk. If your rack airflow is reversed, select the MSN3700-VS2RC variant instead. Verify the ordering suffix on NVIDIA's SN3000 ordering-information page, since NVIDIA documentation specifically warns to pay attention to airflow direction when ordering.
Confirm the intended operating system image before deployment: the VS2FC configuration comes with Cumulus Linux, but other SN3700 SKUs may ship with ONYX or other loads per NVIDIA ordering information. Migrating between NOS images requires re-imaging via ONIE. Also note port speed flexibility (1GbE to 400GbE across the series) depends on the transceiver/SFP module used - use NVIDIA-qualified QSFP56/QSFP28 optics and DACs to avoid link-training and firmware compatibility issues.
