The HPE P26256-B21 Broadcom BCM57412 Ethernet Adapter provides dual-port 10Gb Ethernet connectivity for compatible HPE servers. Designed in the OCP 3.0 form factor, it features two SFP+ ports and a PCI Express 3.0 x8 host interface.
This adapter is suitable for businesses upgrading server connectivity, maintaining virtualised environments or connecting supported servers to high-speed Ethernet infrastructure. Its SFP+ interfaces allow the use of qualified optical transceivers or direct-attach cables.
Unlike a conventional stand-up PCIe network card, P26256-B21 requires a compatible OCP 3.0 networking slot.

Important: The SFP+ ports are not RJ-45 sockets. Check transceiver, cable and switch compatibility before purchasing. Optical modules and cables should not be assumed to be included.
HPE documents P26256-B21 for selected ProLiant Gen10 Plus and Gen11 server configurations. However, support depends on the exact server model, available OCP slot, firmware and operating system.
Before ordering, confirm that your server supports the Broadcom BCM57412 OCP3 adapter and check the relevant HPE QuickSpecs.
For replacement projects, also compare the existing adapter’s part number and connector arrangement. An OCP 3.0 adapter cannot be installed directly into a conventional stand-up PCIe expansion slot.
The P26256-B21 provides two SFP+ ports for connecting to compatible Ethernet switches. Each port supports up to 10Gbps with qualified network equipment.
Supported 1GbE operation depends on the transceiver and connected equipment. For optical links, verify the appropriate fibre type, connector and supported distance. Direct-attach copper cables may be suitable for short connections within a rack or between nearby systems.
The adapter can be used in supported server networking environments that require separate physical connections, network segmentation or redundancy.
The Broadcom BCM57412 supports RoCEv1 and RoCEv2, enabling RDMA over Ethernet for compatible applications. It also supports SR-IOV and network offload functions including VXLAN, NVGRE and GENEVE.
These features may be useful in virtualised server environments and supported storage networking applications. Their availability depends on the installed drivers, firmware, operating system and network configuration.
HPE offers two Broadcom BCM57412 dual-port SFP+ adapters with different installation formats:
Although both belong to the BCM57412 family, they are not physically interchangeable. Select the version supported by your server’s networking slot.
A New or unused adapter may be suitable for planned network upgrades or replacement inventory. Confirm the product condition, packaging, warranty and included accessories before ordering.
A Refurbished P26256-B21 may offer a cost-effective option for maintaining compatible HPE servers. Buyers should request confirmation of physical inspection, adapter detection and functional testing of both SFP+ ports.
For either condition, check stock availability, warranty coverage and UK delivery arrangements with Euroland IT Store.
Before installation, confirm that the server has a supported OCP 3.0 slot and follow the relevant HPE maintenance instructions.
After fitting the adapter, verify that the Broadcom controller is detected correctly and install the supported firmware and network drivers.
Connect qualified transceivers or cables, test both network ports and confirm the negotiated link speeds. If RDMA, SR-IOV or network boot features are required, validate them before production use.
