HPE P06154-B21 — Mellanox MCX653105A-HDAT ConnectX-6 VPI HDR 200Gb 1-Port QSFP56 Adapter (Option Kit)
Technical Identity
The HPE P06154-B21 is the HPE option kit part number for the NVIDIA Mellanox MCX653105A-HDAT: a ConnectX-6 VPI adapter with a single QSFP56 port running HDR InfiniBand at 200Gb/s or 200GbE Ethernet. HPE markets it as the “HPE InfiniBand HDR/Ethernet 200Gb 1-port 940QSFP56 Adapter”. The documented HPE spare (service) part number is P08354-001. HPE positions the adapter for ProLiant XL and DL Gen10 and Gen10 Plus HPC systems. Condition: Refurbished.

Engineering Context: option kit (-B21) versus spare (-001)
HPE uses two part-number forms for the same physical adapter. A -B21 number such as P06154-B21 is an option kit: the orderable, customer-installable product, boxed with bracket and documentation, and the number that appears in HPE QuickSpecs and configurators. A -001 number is a spare / assembly part number used by HPE service to replace a failed board, normally supplied as a bare assembly. For P06154-B21 the documented spare is P08354-001. The silicon is the same; the difference is packaging, accessory content and procurement path. Buyers matching an HPE bill of materials or support contract usually need the -B21 option number specifically.
Use Cases

HDR 200Gb/s InfiniBand host connectivity for HPE ProLiant XL and DL Gen10 / Gen10 Plus HPC and AI nodes.
200GbE RoCE host connectivity for RDMA-attached storage and low-latency Ethernet fabrics.
Adding an HPE-numbered option kit to an existing HPE configuration or bill of materials.

What This Is NOT

NOT a dual-port adapter. P06154-B21 / MCX653105A-HDAT has one QSFP56 port. The dual-port ConnectX-6 VPI HDR card is MCX653106A-HDAT.
NOT a Socket Direct kit. No MTMK0012 auxiliary card or harness is included. Socket Direct configurations are supplied as a separate multi-card kit.
NOT the P08354-001 bare spare. This listing is the P06154-B21 option kit number; the spare board form carries a different number and packaging.
NOT the P23664-B21 option. That is HPE’s separately numbered PCIe4 x16 HDR 200Gb 1-port QSFP56 option kit for the same underlying card family.
NOT NDR 400Gb capable. Maximum per-port rate is HDR 200Gb/s. NDR 400Gb/s requires ConnectX-7.
NOT a QSFP28 or OSFP adapter. QSFP56 cage. QSFP28 modules operate at up to 100Gb/s only; OSFP modules will not fit.
NOT supplied with QSFP56 transceivers, DAC or AOC cables, or alternate-height brackets.

Compatibility & Hard Constraints

Typical InfiniBand switches: NVIDIA Quantum HDR systems such as the QM8700 and QM8790 families at 200Gb/s per port.
Typical Ethernet switches: NVIDIA Spectrum-2 200GbE systems and other 200GbE QSFP56 switches, when the port is configured for Ethernet.
Typical cabling: QSFP56 HDR / 200GbE passive copper DAC, active optical cable, or QSFP56 transceivers. Verify module recognition at both ends.
Host slot: PCIe x16. A PCIe 3.0 x16 slot limits achievable throughput below 200Gb/s line rate — confirm the slot generation against the required bandwidth.
Drivers and firmware: MLNX_OFED or DOCA on Linux, in-box mlx5_core, WinOF-2 on Windows, nmlx5 on ESXi. HPE-branded cards may ship an HPE firmware image; confirm the level against the target fabric.
Pre-deployment verification: option versus spare number on the label, firmware level, bracket height, host slot generation, port mode.

Frequently Asked Questions (FAQ)
Q. What is the HPE P06154-B21?
The HPE option kit part number for a Mellanox MCX653105A-HDAT ConnectX-6 VPI adapter: one QSFP56 port at HDR InfiniBand 200Gb/s or 200GbE Ethernet. HPE calls it the InfiniBand HDR/Ethernet 200Gb 1-port 940QSFP56 Adapter.
Q. What is the difference between P06154-B21 and a -001 spare number?
P06154-B21 is the orderable option kit — boxed, customer-installable, with bracket and documentation, and the number used in HPE QuickSpecs. A -001 number is an HPE service spare, normally the bare assembly. The documented spare here is P08354-001.
Q. How many ports does the P06154-B21 have?
One QSFP56 port. The dual-port ConnectX-6 VPI HDR equivalent is MCX653106A-HDAT.
Q. Is the P06154-B21 PCIe 3.0 or PCIe 4.0?
HPE designates this option kit PCIe3 x16, reflecting the Gen10 platforms it was qualified for. The underlying MCX653105A-HDAT board is PCIe 4.0 x16 and backward compatible with PCIe 3.0 x16. A PCIe 3.0 x16 slot caps throughput below 200Gb/s line rate.
Q. Does P06154-B21 include the MTMK0012 Socket Direct auxiliary card?
No. This is a single-card option kit. Socket Direct configurations pairing MCX653105A-HDAT with an MTMK0012 auxiliary board are supplied as a separate kit.
Q. Can the P06154-B21 run Ethernet instead of InfiniBand?
Yes, it is a VPI adapter — the port can be set to InfiniBand or Ethernet mode with mlxconfig. Confirm the firmware level and switch-side port profile before changing modes.
