What is the NVIDIA/Mellanox equivalent of the HPE P65330-001?

The NVIDIA cross-reference part number is MCP7Y40-N003 (980-9I75R-00N003). The HPE P65330-001 is the OEM-branded version with identical specifications.

Is the P65330-001 compatible with ConnectX-6 adapters?

No. ConnectX-6 uses QSFP56 with 50G PAM4 signaling. The P65330-001 requires ConnectX-7 QSFP112 ports with 100G PAM4 signaling. They are not electrically compatible.

Can this cable be used with Ethernet switches?

This cable is designed for InfiniBand NDR. Physical fit with OSFP/QSFP112 Ethernet ports is possible, but electrical compatibility depends on the switch and NIC supporting 100G PAM4 lane splitting. Verify with your hardware documentation.

HPE P65330-001 (MCP7Y40-N003) InfiniBand NDR200 OSFP to 4xQSFP112 Passive DAC Fanout Cable, 3m: This is a 3-meter passive copper breakout cable that splits a single 800Gb/s OSFP switch port into four individual 200Gb/s QSFP112 compute endpoints. It is an HPE-branded version of the NVIDIA Mellanox MCP7Y40-N003, with identical electrical specifications. This is a fixed-length integrated assembly. This unit is New.

Engineering Context

The P65330-001 is HPE's OEM-labeled equivalent of the NVIDIA MCP7Y40-N003 (reference P/N: 980-9I75R-00N003). At 3 meters, this is near the maximum practical distance for passive copper at NDR200 speeds. The cable uses shielded twinaxial construction for complete EMI immunity. As a passive device, it consumes zero power and provides deterministic latency essential for synchronized AI training workloads.

Deployment & Use Cases

HPC clusters using NVIDIA Quantum-2 InfiniBand NDR. AI/ML model training nodes connecting compute to switch. Low-latency storage interconnects requiring NDR200 throughput. Short-reach intra-rack connectivity for HPE Cray EX supercomputing cabinets and standard rack-mount servers.
