Networking — InfiniBand & High-Speed Ethernet

Moyan Technology supplies the fabric that lashes AI accelerators into a cluster — NVIDIA Quantum InfiniBand (NDR 400G / XDR 800G), high-speed Ethernet (400/800G RoCE, Spectrum-X), ConnectX-7/8 NICs, BlueField-3 DPUs, and the optical transceivers and DAC/AOC cables that connect them. Networking is a high-value, high-line-count category: a single cluster BOM holds thousands of interconnect items, and we quote them together.

We source switches and NICs alongside the Taiwan and China transceiver and cable makers that supply most of the world’s 800G optics, with indicative pricing confirmed at RFQ.

What we supply

InfiniBand switches — Quantum-2 (QM9700/QM9790), Quantum-X800 (Q3400/Q3200).
Ethernet switches — Spectrum-4 SN5600 (800G), SN5400 (400G).
NICs & DPUs — ConnectX-7 (400G), ConnectX-8 (800G), BlueField-3.
Optics & cables — 800G OSFP SR8/DR8 transceivers, passive DAC, AOC, breakouts.

Parts, speeds and indicative prices are in the catalog table on this page (stamped “as of” a date; confirm live at RFQ).

Why source networking through Moyan Technology

Whole-fabric quotes — switches, NICs, DPUs, optics and cables in one BOM.
Optics-supply aware — 800G/1.6T transceivers are the tightest link; we help secure allocation early.
Multi-vendor — NVIDIA InfiniBand or Ethernet white-box on Broadcom silicon.
Authenticity-checked — part numbers and warranty terms verified.

Connect your GPU nodes and design the fabric alongside racks and power.

FAQ

InfiniBand or Ethernet for AI training? InfiniBand (with in-network SHARP) leads for tightly-coupled training; Ethernet with RoCEv2 (Spectrum-X, Tomahawk) suits multi-vendor sourcing and lower per-port cost. We quote either.

What is a BlueField DPU for? It offloads networking, storage and security from the host CPU. BlueField-3 pairs with 200G+ fabrics; we can advise on fit.

Can you supply 800G optics in volume? Yes — from leading Taiwan/China transceiver makers. Note that optics, not switches, are usually the supply constraint, so plan allocation early.

Do you quote a full cluster fabric? Yes — send GPU count and topology and we return an indicative fabric BOM (switches, NICs, DPUs, optics, cables).
