NVIDIA Mellanox® MSX6710G-FS2F2 — FDR / 40GbE VPI Gateway Switch

Technical Identity
The NVIDIA Mellanox® MSX6710G-FS2F2 is a 1U managed VPI (Virtual Protocol Interconnect) gateway switch built on the SwitchX-2 ASIC. It exposes 36× QSFP+ ports that can each be configured as 56 Gb/s FDR InfiniBand or 40 GbE Ethernet, and the chassis can bridge between protocols on the same fabric. Suffix decoding: F = front-to-rear (P2C) airflow, S = managed software, 2 = dual hot-swap PSUs (1+1), F2 = 2 hot-swap fan trays. VPI dual-protocol.

Capabilities & Features

Non-blocking cut-through forwarding across all 36 ports.
VPI dual-protocol: per-port IB or Ethernet assignment.

Adaptive routing, congestion control, per-port telemetry.
Hot-swap PSUs and fan trays.
Embedded subnet manager for mid-size HPC and storage fabrics.


What This Is NOT

NOT an EDR / HDR / NDR IB switch — this is FDR (56 Gb/s). For EDR/HDR/NDR use Quantum-1 / Quantum-2 (MQM‑ series).
NOT a 100/200/400 GbE switch — max Ethernet rate is 40 GbE. For 100 GbE+ use the Spectrum family (SN‑ series).
NOT a NIC or adapter card — it is a rack switch.
NOT bundled with QSFP+ DACs, AOCs, transceivers, or rail kits unless explicitly listed.
NOT a QSFP28 / QSFP56 / OSFP system — QSFP+ cages only.


Compatibility & Constraints

Host adapters: NVIDIA Mellanox ConnectX-3, ConnectX-3 Pro, ConnectX-4, ConnectX-4 Lx with QSFP+ ports. ConnectX-5/6/7 in QSFP+ mode also link.
DAC: MC2207130-xxx, MC2207126-xxx — QSFP+ to QSFP+, FDR / 40GbE.
AOC: MC2207310-xxx — FDR / 40GbE QSFP+ AOC.
Optics: MC2210411-SR4, MC2210511-SR4L — QSFP+ short-reach over MMF (OM3/OM4).
10 GbE breakout: QSFP+ to 4×SFP+ DAC / AOC splitters.
Driver: MLNX_OFED / DOCA on hosts; verify firmware vs. fabric topology.
Power: Dual‑corded recommended, 100–240 VAC.
Cabinet: Standard 19” rack, 1U vertical clearance, hot-aisle exhaust.


Deployment & Use Cases

FDR IB backbone for mid-size HPC clusters, Lustre / GPFS, NVMe-oF over IB.
IB-to-Ethernet gateway between IB compute and 10/40 GbE storage / management.
Storage spine for FDR-attached arrays and 40 GbE‑attached NAS.
Refurb / replacement spine for installed SwitchX-2 fleets.
Lab / staging fabric for MLNX-OS / Onyx validation.


Frequently Asked Questions (FAQ)
Q. What is the NVIDIA Mellanox MSX6710G-FS2F2?
A 1U managed VPI gateway switch from the SwitchX-2 family with 36× QSFP+ ports. Each port runs 56 Gb/s FDR InfiniBand or 40 GbE Ethernet, and the switch can bridge between the two on the same chassis. "FS2F2" = front-to-rear airflow, managed (MLNX-OS / NVIDIA Onyx), 2 PSUs, 2 fan trays.
Q. What does the "G" in MSX6710G mean?
Gateway-capable. VPI dual-protocol; ports can be assigned per protocol and the switch can act as an IB-to-Ethernet gateway in 1U. The non-G MSX6710 is IB-only.
Q. What speeds and protocols does it run?
InfiniBand: 56 Gb/s FDR per port (auto-negotiates FDR10 / QDR / DDR / SDR). Ethernet: 40 GbE per port (10 GbE via QSFP+‑to‑SFP+ breakout). It is not EDR / HDR / NDR and does not run 100 / 200 GbE — those are Quantum / Spectrum generations.
Q. Which adapters and cables are compatible?
ConnectX-3 / 3 Pro / 4 / 4 Lx with QSFP+ ports. QSFP+ passive DAC, QSFP+ AOC, or FDR-rated optical transceivers + MMF (e.g. MC2207130-xxx, MC2207126-xxx, MC2207312-xxx). For 10 GbE links, use QSFP+‑to‑4×SFP+ splitter DACs / AOCs.
Q. Is this part of Quantum / Spectrum?
No. MSX6710G runs the SwitchX-2 ASIC. Quantum is HDR / NDR IB; Spectrum is 10/25/40/100/200/400 GbE Ethernet. SwitchX-2 predates both and tops out at FDR IB and 40 GbE.
Q. What management interfaces are available?
MLNX-OS / NVIDIA Onyx via RS-232 console, dedicated 1 GbE mgmt port, SSH CLI, web UI, SNMP v1/2c/3, REST / JSON RPC. Embedded subnet manager for IB fabrics.
Q. What is the condition supplied by T.E.S IT-SOLUTIONS?
