NVIDIA SN4410 – 24 x QSFP28-DD 100GbE + 8 x QSFP-DD 400GbE Spectrum-3 Open Ethernet Switch
The NVIDIA SN4410 is a fixed-configuration Open Ethernet switch built on the NVIDIA Spectrum-3 ASIC, providing 24 x QSFP28-DD 100GbE + 8 x QSFP-DD 400GbE in a 1U form factor. It delivers 8 Tbps of switching throughput and processes up to 8.4 Bpps, backed by a 64 MB fully shared packet buffer. This page covers the SN4410 model family; each factory part number has its own product page linked in the variant list below.
Key Specifications

Power supplies: 2 hot-swappable AC PSUs (1+1 redundant)
Typical power: 460 W
Airflow options: P2C (rear intake, port-side exhaust) and C2P (port-side intake, rear exhaust) – see the variant list; all FRUs in one chassis must share the same direction
Factory software designations: Cumulus Linux, ONIE – note: software licensing, subscription and support entitlements are not conveyed with refurbished hardware
SN4410 Part Numbers and Variants
SN4410 systems circulate on the secondary market under Mellanox-format OPNs (MSN…). Variants differ by airflow direction, factory software designation and port speed class. Match airflow to your aisle layout and confirm optics/cables separately.
MSN4410-WS2FC – Cumulus Linux (license not included), P2C (rear intake, port-side exhaust)
MSN4410-WS2FO – ONIE (license not included), P2C (rear intake, port-side exhaust)
MSN4410-WS2RO – ONIE (license not included), C2P (port-side intake, rear exhaust)
Other factory builds circulate on the secondary market. If you need a specific OPN that is not listed here, request a quote and we will source it.
Port Flexibility and Breakout
400GbE QSFP-DD uplinks split down to 2 x 200GbE / 4 x 100GbE; leaf ports run 100GbE down to 1GbE. Actual modes depend on the installed network OS version and transceivers.
Spectrum-3 Architecture
SN4410 systems are built on the NVIDIA Spectrum-3 switching ASIC with a fully shared, monolithic packet buffer – every port can draw on the entire buffer, which absorbs microbursts and many-to-one incast far better than segmented-buffer designs in the same class. The platform supports RoCE (RDMA over Converged Ethernet) for storage and AI east-west traffic, rich telemetry with NVIDIA What Just Happened (WJH) hardware-level visibility, and the Open Ethernet model: the same hardware runs multiple network operating systems, so the fabric is never locked to one vendor stack.
Deployment Scenarios
100G server racks with 400G uplinks: 24 x 100GbE leaf ports plus 8 x 400GbE spine-facing uplinks in 1U
Storage and AI pods: RoCE-optimized forwarding with the Spectrum-3 fully shared buffer
Fabric consolidation: one platform bridges 100GbE server access and a 400GbE core
SN4410 Price and Availability
Refurbished SN4410 systems are typically quoted per project: airflow variant, software designation, optics and quantity all move the number. Refurbished units price well below new list. For current SN4410 pricing, request a quote – a BrightStar specialist will respond with availability, condition and warranty terms.
Frequently Asked Questions
How much does a used NVIDIA SN4410 cost?
Pricing depends on the exact OPN, airflow variant, condition and quantity, and secondary-market supply moves week to week. Request a quote for current refurbished pricing – it is typically well below new list for equivalent hardware.
What software does the SN4410 run?
Factory builds of the SN4410 carry the following designations: Cumulus Linux, ONIE. As with all refurbished hardware, software licensing, subscription and support entitlements are not conveyed with refurbished hardware – units are tested on original-spec firmware, factory reset, and configuration wiped. Confirm any OS licensing or support requirements with NVIDIA for your production environment.
What airflow directions are available for the SN4410?
The SN4410 is available as C2P (connector-to-power): air intake at the connector (port) side, exhaust at the power/fan (rear) side – red FRU handles or dots; and as P2C (power-to-connector): air intake at the power/fan (rear) side, exhaust at the connector (port) side – blue FRU handles or dots. All FRUs in one chassis must share the same airflow direction. Note that NVIDIA’s F/R lettering does not map to other vendors’ conventions – always confirm with the intake/exhaust wording on the variant page.
Is a refurbished SN4410 tested before shipping?
Yes. BrightStar Systems inspects and tests every unit on original-spec firmware, performs a factory reset and configuration wipe, and backs it with warranty (1 year end-user / 90 days reseller).
