MSN3700-CS2RO Présentation
A data center Ethernet switch is a network device that forwards Layer 2 and Layer 3 frames and packets between servers, storage systems, and upstream networks. Within the networking hierarchy, the switch sits above the physical cabling layer and below the routing overlay, forming the leaf and spine fabric of modern cloud and enterprise data centers. Open Ethernet switches such as this one ship without a pre-installed network operating system, allowing installation of SONiC, Cumulus Linux, or another NOS through the ONIE boot loader.
Key features include the Spectrum-2 ASIC (second-generation Spectrum family), 32 QSFP28 ports spanning speeds from 1GbE to 100GbE, L3 managed operation, and connector-to-power (C2P) airflow for hot-aisle exhaust compatibility. The dual redundant AC power supplies accept 100-264 V AC input, and the standard-depth 1U chassis is rack-mountable with the included rail kit.
The Spectrum-2 architecture is purpose-built for leaf, spine, and super-spine topologies, providing ultra-low latency and high pipe efficiency for east-west traffic. Port speeds from 1GbE to 400GbE across the SN3000 series allow full-rack server connectivity at any speed with a single platform family.
Typical applications include cloud data center leaf-spine fabrics, enterprise core networks, high-performance computing interconnects, and storage area network fabrics requiring predictable 100GbE throughput.
Design consideration: verify airflow direction and PSU type before ordering, since the SN3000 family uses airflow and power suffixes (CS2RO = C2P airflow, 2x AC) that are not field-interchangeable in some deployments.

Applications typiques
MSN3700-CS2RO convient pour 6 applications: Data Center Leaf-Spine Fabric, Cloud and Hyperscale Networking, Enterprise Core and Aggregation Networks, High-Performance Computing Interconnect, Storage Area Network Fabrics, AI and Machine Learning Cluster Back-End Networks.
Data Center Leaf-Spine Fabric
The MSN3700-CS2RO is purpose-built for leaf and spine roles in modern data center fabrics. Its 32 QSFP28 ports at up to 100GbE and non-blocking 12.8 Tb/s capacity allow full-rack server connectivity without oversubscription at the leaf layer. In spine deployments, all 32 ports can serve as uplinks toward leaf switches, delivering up to 8.33 Bpps of forwarding for east-west traffic at ultra-low latency. The Spectrum-2 ASIC provides consistent latency across the port count, and the ONIE boot loader enables deployment with SONiC, Cumulus Linux, or another Open Ethernet NOS. Because the platform family spans 1GbE to 400GbE, fabric operators can standardize on SN3000-series systems while scaling port speeds generation over generation.

Cloud and Hyperscale Networking
Cloud providers use bare-metal Open Ethernet switches like the MSN3700-CS2RO to decouple hardware from network software. The ONIE boot loader and x86 CPU allow automated provisioning of a chosen NOS through zero-touch installation, which is essential at hyperscale rollout volumes. The dual redundant AC power supplies (100-264 V AC input) and C2P airflow match standard hyperscale rack designs, while the standard-depth 1U chassis maximizes rack density. With 12.8 Tb/s of switching and 8.33 Bpps forwarding, the platform sustains heavy north-south and east-west tenant traffic. Ultra-low latency on the Spectrum-2 ASIC supports performance-sensitive cloud services such as distributed storage and real-time analytics at cost-effective per-port pricing.
Recommandé
Enterprise Core and Aggregation Networks
Enterprise networks deploy the MSN3700-CS2RO as a core or aggregation switch where L3 managed operation is required. The Spectrum-2 ASIC performs hardware L2 switching and L3 routing, supporting routed leaf-spine designs without an external router. The 32 x 100GbE QSFP28 ports break out to 40GbE or lower speeds, letting enterprises aggregate existing 10G/25G/40G access layers while migrating toward 100GbE. Redundant AC power supplies and rack-mountable 1U standard-depth packaging fit conventional enterprise wiring closets and data halls. Operating as a bare-metal ONIE system, the platform allows enterprises to standardize on a single NOS across the network, simplifying automation with tools like Ansible and improving operational consistency.

High-Performance Computing Interconnect
HPC clusters benefit from the MSN3700-CS2RO's ultra-low latency Ethernet switching for storage and management fabrics, complementing InfiniBand compute interconnects. The 12.8 Tb/s non-blocking capacity and 8.33 Bpps forwarding sustain parallel filesystem traffic and job scheduling communication without congestion collapse. C2P airflow and dual redundant 100-264 V AC power supplies align with dense HPC rack cooling and power topologies. The Spectrum-2 ASIC's deterministic latency supports tightly coupled applications that communicate over Ethernet-based storage protocols such as NVMe-oF and Lustre over Ethernet. Because the system is ONIE-based, HPC sites can run specialized NOS builds tuned for the cluster fabric, integrating with slurm and parallel tooling ecosystems.
Recommandé
Storage Area Network Fabrics
The MSN3700-CS2RO serves as a 100GbE storage fabric switch for NVMe-oF, iSCSI, and Ethernet-based SAN deployments. Its 32 QSFP28 ports connect dense arrays of storage servers and flash arrays at 100GbE with line-rate forwarding up to 8.33 Bpps, keeping storage latency dominated by the media rather than the network. The 12.8 Tb/s non-blocking architecture prevents oversubscription during parallel read/write bursts, which is critical for consistent IOPS and throughput in virtualized environments. Dual redundant AC power supplies and C2P airflow support the high-availability requirements of tier-1 storage networks. ONIE-based NOS deployment lets storage teams run validated configurations that integrate with their storage orchestration and monitoring stacks.
Recommandé
AI and Machine Learning Cluster Back-End Networks
AI training clusters increasingly use 100GbE RoCE back-end fabrics, and the MSN3700-CS2RO provides the leaf/spine switching for those topologies. The Spectrum-2 ASIC's ultra-low latency and 12.8 Tb/s capacity handle the all-reduce and gradient-exchange traffic patterns characteristic of distributed training, while 8.33 Bpps forwarding sustains many concurrent GPU node conversations without head-of-line blocking. QSFP28 ports break out to 4x25GbE for connecting hosts with 25G-per-lane adapters, or run full 100GbE to ConnectX-class NICs. Dual redundant AC supplies and C2P airflow match GPU rack power and cooling designs, and ONIE allows deployment of RoCE-tuned NOS builds with PFC and ECN configured for lossless traffic classes.

Notes de conception
Verify airflow direction before ordering. The CS2RO uses C2P (Connector-to-Power) airflow; the CS2FO variant is the identical system with reversed P2C airflow. NVIDIA's SN3000 ordering information explicitly warns to pay attention to airflow when ordering, because a mismatched airflow direction exhausts hot air into the cold aisle and can trigger thermal throttling or shutdown in mixed-airflow racks. Confirm rack cooling orientation against the front-to-back direction implied by the suffix before purchase.
The system ships with 2 x AC power supplies accepting 100-264 V AC input. For N+1 redundancy, connect each PSU to a separate power feed or A/B rack PDUs. Sites with a DC power plant must order the DC-suffix variant (CS2RC class) instead, since AC and PSU modules are not interchangeable in normal deployment. Verify upstream breaker capacity for dual-PSU inrush at 100 V AC sites, where input current is highest.
Although this is a complete switch system, deployment planning matters: the unit is standard-depth and 1U rack-mountable with the included rail kit, so verify rack depth and rear service clearance for PSU replacement. Allow at least 1U of clearance above and below for airflow, and confirm front (connector-side) intake is unobstructed given the C2P airflow. Blank adjacent panels improve airflow efficiency in partially populated racks.
