MSN3700-VS2RO Présentation
A data center Ethernet switch is a managed networking device that aggregates and routes traffic between servers at the leaf, spine, or super-spine layer of a fabric hierarchy. Within the broader networking hierarchy, the MSN3700-VS2RO sits in the top-of-rack or end-of-row switch category, which in turn belongs to the Ethernet switch family of network switching equipment. Open Ethernet switches such as this one ship with ONIE, allowing installation of a choice of network operating systems rather than a locked-in vendor OS.
Key features include 32 QSFP56 ports supporting speeds from 1GbE up to 200GbE per port, 12.8 Tbps non-blocking capacity, redundant hot-swappable 2x AC power supplies, and connector-to-power airflow for predictable thermal management in data center hot/cold aisle layouts. The integrated x86 management CPU enables full-featured NOS deployment including NVIDIA Onyx or Cumulus Linux.
Technically, the Spectrum-2 generation ASIC provides deep buffering and flexible port bifurcation (for example, a 200G port split into 2x100G or 4x50G), enabling mixed-speed rack connectivity. Port speeds span 1GbE to 400GbE across the SN3000 series platform family, giving fabric designers flexibility in leaf/spine blocking ratios.
Typical applications include high-density 100G/200G leaf-spine data center fabrics, super-spine aggregation layers, cloud and enterprise top-of-rack aggregation, and storage network backends where 200GbE uplinks reduce oversubscription.
When deploying, verify rack airflow direction compatibility (C2P versus P2C variants exist in the same family) and confirm AC power feed redundancy before installation.

Applications typiques
MSN3700-VS2RO convient pour 6 applications: 200G Spine Layer Switching, High-Density Leaf Switching, Super-Spine Aggregation, Cloud and Enterprise Data Center Fabrics, Storage Network Backend, High-Performance Computing Interconnect On-Ramp.
200G Spine Layer Switching
The MSN3700-VS2RO fits spine roles in leaf-spine fabrics where 32 x QSFP56 ports at up to 200GbE provide 12.8 Tbps of non-blocking bisection bandwidth. Each 200G port can bifurcate into 2 x 100G or 4 x 50G connections, allowing a single spine chassis to connect 64 leaf switches at 100G or 128 at 50G. The Spectrum-2 ASIC's deep buffering absorbs incast congestion typical of East-West traffic, while redundant 2x AC PSUs and C2P airflow match standard spine rack power and cooling designs. Running EVPN-VXLAN or BGP underlay via an ONIE-installed NOS delivers deterministic fabric convergence.
Recommandé
High-Density Leaf Switching
As a leaf switch, the MSN3700-VS2RO aggregates servers via 100G/50G breakout connections from its 32 QSFP56 ports while pushing 200G uplinks to the spine, minimizing oversubscription. The 12.8 Tbps Spectrum-2 capacity supports full 64 x 100G server connectivity per switch, and ONIE compatibility lets operators standardize on Cumulus Linux or NVIDIA Onyx across the leaf layer for automation with Ansible or JSON-RPC. The 0 C to +40 C operating range and standard-depth 1U chassis fit conventional top-of-rack deployments; C2P airflow requires the switch front face at the cold aisle.
Recommandé
Super-Spine Aggregation
In three-tier data center topologies, the MSN3700-VS2RO serves as a compact super-spine, interconnecting multiple spine blocks over 200G links. With 32 QSFP56 ports it consolidates up to 32 spine-block uplinks, and its Spectrum-2 ASIC forwarding performance sustains line-rate 200G forwarding across all ports for 12.8 Tbps aggregate. The x86 CPU hosts the NOS control plane and telemetry agents for intent-based fabric monitoring. Dual AC power supplies protect against feed loss in the aggregation core, where a chassis outage affects multiple racks; 0-40 C ratings suit dedicated core distribution rooms.
Recommandé
Cloud and Enterprise Data Center Fabrics
Cloud providers and large enterprises deploy the MSN3700-VS2RO where Open Ethernet economics matter: the ONIE boot loader frees operators from vendor-locked NOS licensing and supports open-source switch platforms. Port speeds spanning 1GbE to 400GbE within the SN3000 series let one hardware family serve management, storage, and compute fabrics, simplifying spares pools and automation templates. The 12.8 Tbps capacity with deep buffering handles bursty object-storage and virtualization traffic, while rail-kit mounting and standard 1U depth ease high-density rack integration in colocation environments.
Recommandé
Storage Network Backend
NVMe-oF and distributed storage clusters benefit from the MSN3700-VS2RO's 200G backend links, which keep 100G storage nodes fully non-oversubscribed. The Spectrum-2 ASIC's large packet buffer absorbs read/write bursts from parallel filesystem traffic without drops, and 32 ports at 200G connect storage arrays, compute nodes, and head units in a single tier. Redundant hot-swappable AC PSUs and managed QoS via NVIDIA Onyx preserve latency-sensitive storage traffic classes. The 0-40 C operating envelope covers typical storage aisles; C2P airflow aligns with cold-aisle intake conventions.
Recommandé
High-Performance Computing Interconnect On-Ramp
HPC sites running NVIDIA InfiniBand cores use the MSN3700-VS2RO as the Ethernet side of the fabric - connecting login nodes, management networks, and parallel filesystems to compute resources. Its Spectrum-2 architecture shares silicon lineage with Mellanox switching platforms, easing gateway integration, and 12.8 Tbps capacity sustains all-gather and IO-heavy workloads crossing the Ethernet boundary. ONIE-based NOS flexibility suits sites standardizing on open networking stacks, and the standard-depth 1U chassis with C2P airflow drops directly into HPC racks cooled front-to-back within the 0-40 C ambient envelope.

Principaux différenciateurs
- Full 200G per-port density in 32 ports (vs MSN3700-VS2R)
- Open Ethernet with ONIE freedom (vs SSE-SN3700-VS2RC)
- Standard-depth chassis (vs MSN3700-CS2RO)
Notes de conception
Connect the two AC power supplies to independent power feeds (A/B feeds from separate PDUs) to achieve true redundancy; with both PSUs on a single feed, a breaker trip takes the switch offline despite dual supplies. Verify rack PDU capacity against the switch's maximum power draw before deployment - the exact wattage figure should be taken from the NVIDIA SN3000 Hardware User Manual. Use the supplied rail kit to support the standard-depth chassis; do not cantilever-mount a 1U switch of this weight on front brackets alone.
The -VS2RO suffix specifies connector-to-power (C2P) airflow: air enters at the QSFP56 port face and exhausts at the PSU face. Install with the port face toward the cold aisle and PSU face toward the hot aisle. Mixing airflow directions in one rack recirculates hot exhaust and can push internal temperatures above the 0 C to +40 C operating specification. If your rack uses reversed airflow, order the -VS2FC (port-to-power) variant instead of retrofitting fans.
Confirm the exact SKU suffix before purchase: MSN3700 variants differ by depth (VS standard vs CS short), airflow, and PSU type, and mismatches are discovered only at rack-install time. Because this is an ONIE Open Ethernet switch, it ships without a network operating system - schedule NOS installation (NVIDIA Onyx, Cumulus Linux, or third-party) and license procurement before the deployment window. QSFP56 optics and DAC/AOC cables must be on the NVIDIA interoperability list for guaranteed 200G link training.
