MSN3700-CS2RC Visão geral
A data center Ethernet switch is a Layer 2/Layer 3 networking device that interconnects servers, storage, and uplinks within leaf-spine architectures. Within the network hierarchy, it sits above server NICs and below core/super-spine routers, and the MSN3700-CS2RC belongs to the NVIDIA (formerly Mellanox) Spectrum SN3000 family of purpose-built data center switches spanning 1GbE to 400GbE.
Key features include full Layer 3 managed Open Ethernet operation, 32 ports of 100GBase-X QSFP28 connectivity that also break out to 25G/50G speeds, dual redundant hot-swappable AC power supplies (100-264 VAC input), and C2P airflow matching front-to-back rack cooling conventions. The Spectrum-2 silicon enables low-latency forwarding suitable for East-West traffic-heavy modern fabrics.
The Spectrum-2 ASIC is the second generation of NVIDIA Spectrum switching silicon, purpose-built for leaf, spine, and super-spine deployment. Its 425 ns latency and high packet rate sustain full line-rate forwarding across all 32 QSFP28 ports, supporting 100GbE storage networks, machine learning cluster fabrics, and virtualized cloud environments where microsecond-scale delay compounds application performance.
Typical applications include 100GbE leaf-spine data center fabrics, hyperscale and enterprise top-of-rack aggregation, RoCE/AI cluster back-end networks, and Open Ethernet deployments standardized on Cumulus Linux for automation with Ansible-style tooling.
Design consideration: confirm airflow direction (C2P, front-to-back) and AC power provisioning before ordering; NVIDIA explicitly advises checking airflow when selecting SN3000 SKUs, and mismatched airflow causes thermal throttling in hot-aisle containment layouts.

Aplicações típicas
MSN3700-CS2RC é adequado para 6 aplicaçãos: 100GbE Leaf-Spine Data Center Fabric, AI/ML Cluster Back-End Network, Top-of-Rack Server Aggregation, Enterprise Campus Core / Data Center Interconnect, Storage Area Network (100GbE NVMe-oF), Cloud and Hyperscale Open Ethernet Expansion.
100GbE Leaf-Spine Data Center Fabric
The MSN3700-CS2RC is purpose-built for leaf and spine roles in data center leaf-spine topologies. Its 32 x 100GbE QSFP28 ports and 12.8 Tb/s switching capacity allow every leaf to be fully meshed to a spine pair at 100G without oversubscription at moderate scale, while the 425 ns cut-through latency keeps East-West hop delay negligible. Each QSFP28 port can also break out to 25G or 50G for server-facing leaf connections, letting one SKU serve both tiers. Deployed with Cumulus Linux, fabric-wide configuration is automated, and dual AC PSUs sustain availability through a power feed failure.
Recomendado
AI/ML Cluster Back-End Network
AI training clusters generate dense East-West all-reduce traffic that punishes latency and congestion. The MSN3700-CS2RC's Spectrum-2 ASIC forwards at 8.33 Bpps with 425 ns latency, and its non-blocking-class 12.8 Tb/s fabric sustains line-rate RoCE traffic across all 32 QSFP28 ports. Used as the back-end spine of a GPU pod, it interconnects server leaf switches with 100G links while Cumulus Linux enables automated fabric bring-up. For larger pods, multiple units scale the spine, and SN4000-series systems can provide 400G super-spine aggregation when 100G leaf capacity is exhausted.
Recomendado
Top-of-Rack Server Aggregation
As a top-of-rack switch, the MSN3700-CS2RC aggregates up to 32 100G server links, or up to 128 breakout 25G links using QSFP28-to-SFP28 breakout cables, providing full-rack connectivity in a single 1U standard-depth chassis. Dual redundant AC power supplies and C2P front-to-back airflow match conventional rack cooling, and the x86 CPU running Cumulus Linux supports standard automation toolchains. Its 425 ns latency keeps server-to-leaf delay minimal for storage and virtualization traffic, while Layer 3 capability allows routed host interfaces at the rack edge.
Recomendado
Enterprise Campus Core / Data Center Interconnect
Enterprises consolidating server rooms and computer rooms can deploy the MSN3700-CS2RC as a compact 100G core or data center interconnect node. Its Layer 3 managed Open Ethernet stack supports routed uplinks between sites, while the 100-264 VAC dual PSU design tolerates varied facility power. The 12.8 Tb/s fabric comfortably carries aggregated 10G/25G/40G/100G campus traffic, and Cumulus Linux enables consistent configuration management across enterprise sites. Breakout optics allow graceful migration from existing 40G links to 100G without chassis replacement.
Recomendado
Storage Area Network (100GbE NVMe-oF)
NVMe-over-Fabrics storage demands low, consistent latency and lossless-class Ethernet behavior. The MSN3700-CS2RC's 425 ns switch latency and 8.33 Bpps forwarding rate keep storage path overhead far below NVMe protocol tolerances, and its 32 x 100GbE ports connect all-flash arrays and compute nodes in one fabric tier. With Cumulus Linux, ECN/PFC-class settings are manageable fabric-wide for RoCE-based storage traffic. Dual PSUs and 1U density make it practical for dense storage racks with front-to-back airflow containment.
Recomendado
Cloud and Hyperscale Open Ethernet Expansion
Operators standardized on Open Ethernet (merchant-silicon switches running disaggregated NOS) use the MSN3700-CS2RC to expand 100G capacity without vendor lock-in. Cumulus Linux on the onboard x86 CPU supports the same automation, telemetry, and CI/CD provisioning pipelines used across hyperscale fabrics. SN3000-series port flexibility from 1GbE to 100G per port lets management, storage, and compute traffic consolidate on one platform. The refurbished market supply of this SKU makes brownfield capacity expansion cost-effective while preserving configuration parity with existing SN3700C deployments.

Notas de projeto
Verify airflow direction before ordering. NVIDIA's SN3000 ordering-information documentation explicitly warns to pay attention to airflow when ordering systems: the CS2RC uses C2P (front-to-back) airflow. Installing a C2P unit in a rack with rear-to-front cooling containment leads to recirculating hot exhaust, thermal throttling, and premature PSU/fan wear. If the rack exhausts at the front, order a C2O (rear-to-front) variant such as the CS2RO instead.
Provide two independent AC feeds within 100-264 VAC for the dual PSUs to realize redundancy. Connect each PSU to a separate branch circuit or A/B power domain; sharing one feed negates the dual-PSU benefit. Exact typical/max power draw depends on QSFP28 optics population and was not in the verified data - consult the SN3000 Hardware User Manual power tables when sizing branch circuits and UPS capacity.
Rack installation: use the included rail kit and confirm the standard-depth chassis fits the enclosure; leave at least 1U of clearance or blank panel above and below for airflow. Breakout planning matters for cabling cost: QSFP28 ports support 4x25G breakout via MPO/DAC, so pre-plan which ports server-facing (25G/50G breakout) versus spine-facing (100G single-lane) to minimize transceiver spend and simplify Cumulus Linux port-naming conventions.
