HPE P16004-001 MCX512F-ACHT 2Port Adapter

HPE P16004-001 Mellanox MCX512F-ACHT 10/25Gb 2-Port SFP28 Adapter

The HPE P16004-001 Mellanox MCX512F-ACHT Network Adapter is a replacement spare for compatible HPE servers requiring high-speed 10GbE or 25GbE Ethernet connectivity. Featuring two SFP28 ports and a PCIe 3.0 x16 host interface, this adapter is designed for enterprise networking, virtualisation and data-intensive server environments.

P16004-001 is the replacement spare associated with the HPE P13188-B21 Mellanox MCX512F-ACHT Ethernet 10/25Gb 2-Port SFP28 Adapter. It is suitable for businesses replacing an existing network card or maintaining spare hardware for supported HPE server infrastructure.

HPE P16004-001 Technical Specifications

Important: This adapter uses SFP28 ports rather than RJ-45 Ethernet sockets. Supported transceivers, direct-attach cables and switch configurations must be checked separately.

Key Features and Benefits

• Dual-port 10/25GbE: Provides two high-speed Ethernet connections for compatible server environments.
• Replacement spare: Identified by HPE as the spare associated with retail option P13188-B21.
• SFP28 connectivity: Supports qualified optical transceivers and direct-attach cabling.
• PCIe 3.0 x16 interface: Provides a high-bandwidth connection to the host server.
• RDMA capabilities: Supports RoCEv1 and RoCEv2 for suitable low-latency network configurations.
• Virtualisation support: Includes SR-IOV for compatible operating systems and hypervisors.

Compatible HPE Servers

HPE documents P16004-001 in maintenance information for selected server platforms, including the HPE ProLiant DL385 Gen10 Plus and HPE ProLiant XL675d Gen10 Plus.

However, compatibility depends on the exact server model, expansion slot, riser configuration and supported firmware.

Before purchasing, verify:

• The server model and generation.
• The existing adapter’s spare or option part number.
• Availability of a supported PCIe expansion slot.
• The installed operating system and network drivers.
• Required SFP28 transceivers or DAC cables.
• Switch compatibility and supported Ethernet speeds.

Matching the existing adapter to P16004-001 or the corresponding P13188-B21 option is a useful starting point, but the server’s HPE QuickSpecs should be checked before ordering.

10GbE and 25GbE SFP28 Connectivity

The Mellanox MCX512F-ACHT adapter provides two SFP28 interfaces supporting 10GbE and 25GbE operation.

These ports can connect to qualified Ethernet switches using suitable optical transceivers or direct-attach copper cables. Each port supports up to 25Gbps in one direction, giving a theoretical combined one-way port capacity of 50Gbps.

Actual throughput depends on the network configuration, host server, cabling and connected equipment.

For businesses maintaining existing 10GbE networks, the adapter may also support a transition to qualified 25GbE infrastructure without changing the adapter model.

RDMA and Virtualisation Features

HPE P16004-001 supports RoCEv1 and RoCEv2, enabling RDMA over Ethernet in compatible environments. These technologies can help reduce processor overhead for supported applications requiring efficient data movement.

The adapter also supports SR-IOV, which allows compatible virtualisation platforms to allocate network resources more directly to virtual machines.

These features require suitable firmware, drivers, operating system support and network configuration. They should be validated before deployment.

P16004-001 vs P13188-B21: What Is the Difference?

Both part numbers identify the Mellanox MCX512F-ACHT dual-port 10/25GbE adapter family, but they have different purchasing references.

• HPE P16004-001: Replacement spare part number.
• HPE P13188-B21: Retail option part number.

A replacement spare may be supplied without the packaging or accessories associated with the retail option kit.

Confirm the mounting bracket, included transceivers, cables and other components before ordering.

Installation and Replacement Guidance

Before replacing an existing network adapter, record the current network configuration, including port assignments, IP addresses, VLANs and any network teaming settings.

Follow the maintenance instructions for the relevant HPE server when removing and installing the PCIe adapter.

After installation, confirm that the Mellanox controller is detected and that the supported firmware and network drivers are installed.

Connect qualified transceivers or cables and verify the link status and negotiated speed of both SFP28 ports.

If RDMA or SR-IOV functionality is required, test these features within the complete server and network environment before returning the system to production.

New and Refurbished HPE P16004-001

New HPE P16004-001

A New or unused HPE P16004-001 adapter may be suitable for planned server maintenance or maintaining replacement stock. Confirm the supplied part number, packaging, accessories, warranty and availability before ordering.

Refurbished HPE P16004-001

A Refurbished P16004-001 may offer a cost-effective alternative for maintaining compatible HPE server infrastructure. Buyers should request confirmation of physical inspection, adapter recognition and functional testing of both network ports.

For either condition, verify whether optical transceivers or direct-attach cables are included, along with warranty coverage and UK delivery arrangements.
