NVIDIA Mellanox® MSX6036G-2SFS — SwitchX-2 36-Port FDR InfiniBand to 10GbE Gateway Switch

Technical Identity
The NVIDIA Mellanox® MSX6036G-2SFS is a 1U managed SwitchX-2 based InfiniBand-to-Ethernet gateway switch with 36× QSFP+ FDR 56Gb/s InfiniBand ports plus 2× SFP+ 10GbE Ethernet uplink ports for the gateway function. The "G" suffix denotes the Gateway model and "-2SFS" indicates the two SFP+ 10GbE Ethernet bridge ports. The SwitchX-2 ASIC is VPI dual-protocol capable — the 36 QSFP+ ports can also be operated as 40GbE Ethernet when the platform is configured in Ethernet mode. Condition: New, factory-sealed.

What This Is NOT

NOT an EDR / HDR / NDR switch. SwitchX-2 silicon tops out at FDR 56Gb/s per port — do not confuse with Switch-IB (EDR), Quantum (HDR), or Quantum-2 (NDR) generations.
NOT a pure 40GbE Ethernet switch. Spectrum / Spectrum-2 are the dedicated Ethernet families; the MSX6036G is a VPI gateway designed for IB fabrics that need an Ethernet exit.
NOT a NIC, adapter, or HCA. This is a rack-mount switch — requires rack space, PDU power, and structured cabling.
NOT bundled with optical transceivers, DAC / AOC cables, rail kit, or console cables unless explicitly stated.


Compatibility & Constraints

InfiniBand cabling (36× QSFP+ ports): Mellanox MC2207126 / MC2207130 series FDR QSFP+ DAC, MC220731V series FDR AOC, MC2210411 / MC2210511 FDR optical transceivers. Backward compatible with QDR (40Gb/s) and DDR cables at reduced speed.
Ethernet uplinks (2× SFP+ ports): Standard 10GbE SFP+ DAC, SFP+ AOC, or SR/LR optical transceivers (MSA compliant).
Compatible host adapters: NVIDIA Mellanox ConnectX-3 / ConnectX-3 Pro VPI (QSFP+ FDR) on the IB side; any 10GbE NIC on the Ethernet uplink side.
Operating system: MLNX-OS (legacy) or NVIDIA Onyx; firmware should match MLNX_OFED driver stack on hosts.
Power: 100–240 VAC, hot-swap redundant PSUs — verify PDU outlets before deployment.
Airflow: Confirm hot-aisle / cold-aisle orientation matches PSU and fan SKU before rack install.


Frequently Asked Questions (FAQ)
Q. What is the NVIDIA Mellanox MSX6036G-2SFS?
The MSX6036G-2SFS is a 1U managed SwitchX-2 InfiniBand-to-Ethernet gateway switch with 36× QSFP+ FDR 56Gb/s InfiniBand ports and 2× SFP+ 10GbE Ethernet uplink ports. It bridges FDR IB fabrics to 10GbE Ethernet networks.
Q. What generation of InfiniBand does this switch support?
FDR (56Gb/s per port over 4× 14Gb/s lanes) on the SwitchX-2 ASIC. It is backward-compatible with QDR (40Gb/s) and DDR cables and adapters at reduced negotiated speeds. It is NOT EDR, HDR, or NDR.
Q. Can the 36 QSFP+ ports run as 40GbE Ethernet?
Yes — SwitchX-2 is a VPI (Virtual Protocol Interconnect) ASIC. With the appropriate license and Ethernet-mode configuration, the QSFP+ ports operate as 40GbE Ethernet. Port-mode is configured globally or per-port via MLNX-OS / Onyx.
Q. What management interface does this switch support?
MLNX-OS / NVIDIA Onyx via console (RJ45 serial), out-of-band Ethernet management (RJ45), SSH/CLI, SNMP v1/v2/v3, REST API, and Web UI. Embedded subnet manager support for InfiniBand mode.
Q. Is the MSX6036G-2SFS compatible with non-NVIDIA equipment?
The SFP+ and QSFP+ cages are MSA-compliant, so standard third-party 10GbE Ethernet transceivers and DAC cables work on the SFP+ uplinks. On the IB side, ConnectX-3 / ConnectX-3 Pro VPI host adapters are the validated pair; later ConnectX generations (4/5/6/7) negotiate down to FDR but you lose the higher-speed benefits of newer silicon.
Q. What is the condition supplied by T.E.S IT-SOLUTIONS?
New, factory-sealed in original NVIDIA Mellanox packaging where included. Units ship from EU stock with professional anti-static packaging and global B2B shipping. Pre-sale technical consultation for HPC, AI cluster, and gateway-fabric design is included at no extra cost.
