What is the NVIDIA/Mellanox equivalent of the Lenovo 03GX910?

The NVIDIA cross-reference part number is MCP7Y40-N01A (980-9I75D-00N01A). The Lenovo 03GX910 is the OEM-branded version with identical specifications.

Is the 03GX910 compatible with ConnectX-6 adapters?

No. ConnectX-6 uses QSFP56 with 50G PAM4 signaling. The 03GX910 requires ConnectX-7 QSFP112 ports with 100G PAM4 signaling. They are not electrically compatible.

Why use a passive DAC instead of an AOC at 1.5m?

At 1.5m, passive copper provides lower latency, zero power consumption, higher reliability (no active components to fail), and lower cost than active optical cables.

Lenovo 03GX910 (MCP7Y40-N01A) InfiniBand NDR200 OSFP to 4xQSFP112 Passive DAC Breakout Cable, 1.5m: This is a 1.5-meter passive copper hybrid breakout cable that splits a single 800Gb/s OSFP switch port into four individual 200Gb/s QSFP112 compute endpoints. It is a Lenovo-branded version of the NVIDIA Mellanox MCP7Y40-N01A, with identical electrical specifications. The "Hybrid" designation refers to the OSFP-to-QSFP112 connector transition. This is a fixed-length integrated assembly. This unit is New.

Engineering Context

The 03GX910 is Lenovo's OEM-labeled equivalent of the NVIDIA MCP7Y40-N01A. At 1.5 meters, this DAC provides optimal balance between reach and signal integrity for Top-of-Rack topologies. As a passive device, it consumes zero power, offers higher MTBF than active optical alternatives, and provides deterministic latency with complete EMI immunity. The shielded twinaxial construction ensures data integrity in high-noise switching environments.

Deployment & Use Cases

Connecting Lenovo ThinkSystem AI servers or NVIDIA Quantum-2 switches (OSFP) to ConnectX-7 adapters (QSFP112) within the same rack. Cost-effective fanout connectivity maximizing port utilization. HPC nodes requiring sub-microsecond latency. Environments where minimizing active component thermal output is a priority.
