HPE P13188-B21 MCX512F-ACHT 2Port Adapter

HPE P13188-B21 Mellanox MCX512F-ACHT 10/25Gb 2-Port SFP28 Adapter

The HPE P13188-B21 Mellanox MCX512F-ACHT Ethernet Adapter is a dual-port network interface card designed to deliver 10GbE and 25GbE connectivity in compatible HPE servers. With two SFP28 ports and a PCI Express 3.0 x16 host interface, it provides an upgrade path for organisations that need greater network bandwidth without replacing their existing server infrastructure.

Part number P13188-B21 identifies the stand-up PCIe version of the Mellanox MCX512F-ACHT adapter. It is intended for qualified HPE server configurations and can support demanding Ethernet workloads, including virtualisation, data centre networking and RDMA-enabled applications.

HPE P13188-B21 Technical Specifications

Note: Both ports can provide up to 25Gbps connectivity when used with compatible network equipment. Actual throughput depends on the server, transceivers, cabling, switch configuration and workload.

Key Features and Benefits

• Dual 10/25GbE connections: Supports higher-bandwidth networking for compatible enterprise servers.
• SFP28 interfaces: Enables connections using qualified optical transceivers or direct-attach cables.
• PCIe 3.0 x16: Provides the host interface for the stand-up adapter.
• RDMA capabilities: Supports RoCEv1 and RoCEv2 in suitable network environments.
• Virtualisation support: Includes SR-IOV for compatible operating systems and hypervisors.
• Network offload features: Supports technologies including VXLAN and GENEVE to assist with supported virtual networking workloads.

HPE Server Compatibility

The Mellanox MCX512F-ACHT adapter is documented for selected HPE ProLiant and Apollo server configurations. Examples include qualified configurations of the HPE ProLiant DL380 Gen10 and HPE ProLiant DL20 Gen10 Plus, along with selected Apollo systems.

HPE also lists P13188-B21 for specific Gen11 configurations. However, support is not universal across all servers in a generation.

Before purchasing, check the exact server model, available PCIe slot, riser configuration, firmware and operating system against the applicable HPE QuickSpecs.

10GbE and 25GbE SFP28 Networking

The P13188-B21 uses two SFP28 network ports rather than conventional RJ-45 sockets. This makes it appropriate for networks built around compatible high-speed optical or direct-attach connectivity.

It supports 10GbE and 25GbE operation, allowing administrators to select qualified connection speeds based on the connected switch and network equipment.

For installations using HPE Aruba Networking switches, transceiver and cable interoperability should be checked carefully. HPE has documented intermittent interoperability issues with certain 25Gb active optical cables on this adapter and identifies qualified direct-attach copper cables as preferable for the affected combinations.

Transceivers and cables should not be assumed to be included with the adapter.

RDMA and Virtualisation Capabilities

HPE P13188-B21 supports RoCEv1 and RoCEv2, allowing compatible applications to use RDMA over Ethernet. This can be useful for workloads requiring efficient data movement and reduced processor overhead.

The adapter also provides SR-IOV functionality, enabling supported virtualisation platforms to allocate network resources to virtual machines more directly.

These capabilities depend on appropriate server firmware, network drivers, switch settings and operating system support. RDMA performance also depends on the end-to-end network configuration.

P13188-B21 vs P10112-B21

Although both adapters provide dual-port 10/25GbE networking, they use different installation formats.

• HPE P13188-B21: Mellanox MCX512F-ACHT, stand-up PCIe adapter with two SFP28 ports.
• HPE P10112-B21: Mellanox MCX562A-ACAI, OCP 3.0 adapter with two SFP28 ports.

These products are not direct physical substitutes. Choose the adapter specifically qualified for your server’s expansion slot and hardware configuration.

New and Refurbished HPE P13188-B21

New HPE P13188-B21

A New or unused Mellanox MCX512F-ACHT adapter may suit planned network upgrades or spare-part inventory. Confirm the supplied bracket, packaging, accessories, warranty and availability before ordering.

Refurbished HPE P13188-B21

A Refurbished P13188-B21 can be an economical option for maintaining compatible HPE infrastructure. Before purchasing, request confirmation of adapter detection, physical inspection and functional testing of both SFP28 ports.

For either condition, verify the warranty terms and whether any optical modules or cables are included.

Installation and Replacement Guidance

Before installation, check that the target server has a supported PCIe expansion slot and adequate space for the adapter. Follow the maintenance instructions for the specific HPE server model.

After fitting the adapter, confirm that it is detected correctly and install the supported HPE firmware and network drivers. Connect qualified transceivers or cables, then verify both port links and negotiated speeds.

If RDMA, SR-IOV or network boot functions are required, validate those features in the complete server and network configuration before production use.
