DESCRIPTION
NVIDIA MSN4410-WS2FC – SN4410 24 x QSFP28-DD 100GbE + 8 x QSFP-DD 400GbE Open Ethernet Switch
The MSN4410-WS2FC is an NVIDIA SN4410 series 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. NVIDIA’s official ordering description: “NVIDIA Spectrum-3 based 400GbE 1U Open Ethernet Switch with Cumulus Linux, 24 QSFP-DD28 and 8 QSFP-DD ports, 2 AC PSUs”.
Key Features
Ports: 24 x QSFP28-DD 100GbE + 8 x QSFP-DD 400GbE
Port speeds: Ports 1-24: 1/10/25/40/50/100GbE per port; ports 25-32: 1/10/25/40/50/100/200/400GbE per port
Throughput: 8 Tbps
Packet rate: 8.4 Bpps
Packet buffer: 64 MB, fully shared across all ports
Software: Cumulus Linux factory designation – note: software licensing, subscription and support entitlements are not conveyed with refurbished hardware
Airflow: P2C (power-to-connector) – air intake at the power/fan (rear) side, exhaust at the connector (port) side (blue FRU handles/dots)
Power supplies: 2 hot-swappable AC PSUs (1+1 redundant)
Dimensions (HxWxD): 1.72 x 16.85 x 22.3 in (44 x 428 x 568.5 mm)
Part numbers: Legacy OPN MSN4410-WS2FC = NVIDIA 920-9N312-00FB-0C0 (same hardware)
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
Choosing Among the Variants
SN4410 OPNs decode as follows: the letter before the airflow character sets the speed class (B = the lower speed build, C = 100GbE, V = 200GbE, W = 400GbE); F = P2C airflow (power-side intake, port-side exhaust) and R = C2P airflow (port-side intake, power-side exhaust); a trailing C = Cumulus Linux, a trailing O = ONIE only, and no trailing letter = NVIDIA Onyx. Important: NVIDIA’s F/R airflow letters are defined by intake side at the power side or connector side – do not assume they match other vendors’ F/R conventions. Match the airflow variant to your hot-aisle/cold-aisle layout and the software designation to your operations model; the underlying switch hardware within a speed class is otherwise identical.
Mellanox and NVIDIA Part Numbers
The SN4410 was designed by Mellanox Technologies, which NVIDIA acquired in 2020; the same platform has been sold under both the Mellanox and NVIDIA names. It carries two interchangeable part numbers: the original Mellanox-style OPN MSN4410-WS2FC and the newer NVIDIA number 920-9N312-00FB-0C0 – both identify exactly the same hardware. Listings and documentation referring to a “Mellanox SN4410” and an “NVIDIA SN4410” describe the same switch.
Frequently Asked Questions
Is the MSN4410-WS2FC a Mellanox switch or an NVIDIA switch?
Both names refer to the same product. The SN4410 platform was developed by Mellanox, which NVIDIA acquired in 2020. The OPN MSN4410-WS2FC and the NVIDIA part number 920-9N312-00FB-0C0 identify identical hardware.
What software does the MSN4410-WS2FC run?
This OPN designates a factory build with Cumulus Linux, NVIDIA’s Linux-native network OS for automation-driven fabrics. 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 is the airflow direction of the MSN4410-WS2FC?
The MSN4410-WS2FC is the P2C (power-to-connector) variant: air intake at the power/fan (rear) side, exhaust at the connector (port) side. NVIDIA marks this direction with blue handles or dots on the fan and PSU modules. All FRUs in one chassis must share the same airflow direction.
What breakout options does the MSN4410-WS2FC support?
400GbE QSFP-DD uplinks split down to 2 x 200GbE / 4 x 100GbE; leaf ports run 100GbE down to 1GbE.
Is the refurbished MSN4410-WS2FC 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).
