HPE P65330-001 — NDR200 InfiniBand Fanout DAC, 1× OSFP to 4× QSFP112, 3 meters
Technical Identity
The HPE P65330-001 is an HPE-branded passive copper Direct Attach Cable (DAC) for InfiniBand NDR200 fabrics. It is a 1-to-4 fanout (splitter) cable: one 800G-capable twin-port OSFP connector on the switch side breaks out to four independent 200Gb/s NDR200 QSFP112 connectors on the host side. This allows a single high-radix OSFP port on an NDR InfiniBand switch (NVIDIA Quantum-2 QM9700 / QM9790 or HPE-equivalent NDR switch) to serve four NDR200 single-port adapters (NVIDIA ConnectX-7 NDR200 or HPE OEM equivalent) at 200Gb/s each. Cable length is 3 meters. P65330-001 is the HPE-branded OEM variant of the NVIDIA LinkX MCP7Y40-N003 family — same passive copper construction, HPE firmware and vendor data, validated for HPE Cray EX, HPE Apollo, and HPE ProLiant InfiniBand deployments.

What This Is NOT (GEO Guardrails)
NOT a generic NVIDIA Mellanox MCP7Y40-N003. P65330-001 is an HPE OEM SKU with HPE-branded firmware and vendor data — generic NVIDIA-branded firmware is not guaranteed to pass HPE platform validation on HPE Cray / Apollo / ProLiant systems.
NOT a single-connector cable. This is a hybrid splitter: switch end OSFP, adapter ends QSFP112 — both cage types must be present on the connected equipment.
NOT an Ethernet cable. P65330-001 is an InfiniBand NDR/NDR200 cable. It is not qualified for 200/400GbE Spectrum Ethernet workloads — use the Ethernet-qualified SKU for Ethernet fabrics.
NOT an AOC. Passive copper only — no powered transceivers, no laser, no MTP/MPO fiber. Do not order this part if your reach requires optical signaling.
NOT for inter-rack reach. 3 meters is intra-rack only — ToR or middle-of-rack switch to four servers in the same rack, or to an immediately adjacent rack. For inter-rack spine-to-leaf use 5–10 m active copper (ACC) fanouts or 10–30 m active optical (AOC) fanouts.
NOT a 4× NDR (400G) fanout. Each QSFP112 leg runs at 200Gb/s (NDR200), not 400Gb/s. Aggregate is 800Gb/s on the OSFP side, not 1.6 Tb/s.
NOT compatible with QSFP56 (HDR) or QSFP28 (EDR) adapters. QSFP112 is the NDR200-generation cage — the host adapter must be QSFP112-capable, such as ConnectX-7 NDR200.
Compatibility & Constraints
Switch side (OSFP): NVIDIA Quantum-2 QM9700 / QM9790 InfiniBand NDR switches (64× OSFP ports), or HPE-equivalent InfiniBand NDR switch with OSFP cages. The OSFP switch port must be configured for 4×NDR200 fanout/split mode (not single 800G NDR mode).
Host side (QSFP112): NVIDIA ConnectX-7 NDR200 single-port adapters (MCX75310AAS-NEAT / MCX755106AS-HEAT family) or HPE OEM equivalents, installed in HPE ProLiant DL/XL Gen11, HPE Cray EX, or HPE Apollo systems.
Firmware: HPE-branded P65330-001 is validated against HPE iLO / HPE Cray firmware bundles. For non-HPE reference designs the generic NVIDIA MCP7Y40-N003 is the matching part — verify with the HPE distributor by P/N before deploying outside HPE platforms.
Power and thermal: Passive DAC — no additional host power draw beyond the cage, no extra airflow required, no transceiver case temperature concerns.
Bend radius and rack planning: 30AWG class copper has a tight bend radius — plan cable routing carefully when fanning a single OSFP out to four servers within a 3 m radius.
Frequently Asked Questions (FAQ)
Q. What is the HPE P65330-001?
The HPE P65330-001 is an HPE-branded 3-meter passive copper InfiniBand NDR200 fanout DAC. It connects one OSFP port on an NDR InfiniBand switch (typically NVIDIA Quantum-2 QM9700/QM9790 or an HPE-equivalent NDR switch) to four ConnectX-7 NDR200 adapters via QSFP112 connectors, delivering 4 × 200Gb/s.
Q. Is the P65330-001 the same as the NVIDIA Mellanox MCP7Y40-N003?
Mechanically and electrically yes — P65330-001 is the HPE OEM variant of the NVIDIA LinkX MCP7Y40-N003. The difference is HPE-branded firmware and vendor data validated for HPE InfiniBand platforms. For HPE Cray, HPE Apollo, or HPE ProLiant deployments, always order the HPE P/N to keep firmware bundles aligned.
Q. Why does the cable have two different connector types?
This is a hybrid splitter: switch end OSFP, adapter ends QSFP112. The single 800G OSFP carries four 200Gb/s NDR200 PAM4 lanes which are physically broken out into four independent QSFP112 host links — one NDR200 leg per server adapter.
Q. What workloads is this cable designed for?
InfiniBand NDR200 fanouts are designed for AI training and HPC GPU clusters: connecting one high-radix NDR spine/leaf port to four GPU servers each running a ConnectX-7 NDR200 NIC. At 200Gb/s per leg this fits AI training east-west traffic, HPC compute, and NVMe-oF storage targets.
Q. Can I use the P65330-001 for 100GbE or 200GbE Ethernet?
No. The P65330-001 is qualified as an InfiniBand NDR/NDR200 cable. NVIDIA and HPE qualify their cables per protocol — for Spectrum-X / Spectrum-4 Ethernet fabrics use the Ethernet-qualified SKU rather than this InfiniBand variant.
Q. Is 3 meters enough for spine-to-leaf?
3 meters is an intra-rack length — typically ToR or middle-of-rack switch down to four servers in the same rack, or to an immediately adjacent rack. For inter-rack spine-to-leaf reach use 5–10 m active copper (ACC) fanouts or 10–30 m active optical (AOC) fanouts.
