P42045-B21 HPE NVIDIA/Mellanox CONNECTX-6 Dx 100GBE 2-PORT QSFP56 Adapter for HPE

HPE-branded SFP / SFP+ / SFP28 / QSFP+ / QSFP28 transceiver — fiber or DAC copper optic for HPE server NICs and switches.

Specifications

• Part Number: P42045-B21
• Brand: HPE
• Form Factor: SFP (1G) / SFP+ (10G) / SFP28 (25G) / QSFP+ (40G) / QSFP28 (100G) / QSFP-DD (200G/400G) — see PN
• Optic Class: QSFP+
• Speed: 100G Ethernet
• Wavelength: 850nm (SR/MMF) / 1310nm (LR/SMF) / 1550nm (ER/SMF) / coded by class
• Connector: LC duplex (most) / MPO (parallel-fiber QSFP) / RJ45 (BASE-T variants 1G)

Compatibility

HPE transceivers are firmware-keyed — third-party SFPs may work but typically trigger 'unsupported transceiver' warnings. For production use, deploy vendor-original.

• HPE 40G/100G NICs (Mellanox ConnectX HPE-branded): ProLiant Gen10/Gen10 Plus/Gen11 with QSFP+/QSFP28 ports
• HPE/Aruba 40G/100G switches: Aruba CX 8325/8400/10000 / FlexFabric 5945/12900 spine fabrics

Use Cases

Server NIC ports + ToR switch uplinks + SAN HBA ports. SR/MMF for in-rack and short-rack connections (cheaper). LR/SMF for cross-datacenter / cross-MDF runs. DAC copper for in-rack direct attach (lowest latency, lowest cost, no transceiver pair needed). AOC for medium-range (5-30m) where DAC max length insufficient.
