HPE Ethernet 10/25Gb 2-port SFP28 OCP3 Adapter

The HPE P10115-B21 is a two-port Ethernet adapter that lets an HPE Gen10 Plus server link to the network at either 10 or 25 Gbps per port. It installs in an OCP 3.0 slot and draws on the Broadcom BCM57414 controller to deliver consistent throughput while keeping latencies low.

Because each port is SFP28, you can choose direct attach copper cables for short runs or optical transceivers for longer distances. The adapter presents a PCIe Gen3 x8 interface to the system, so it has enough bandwidth to sustain full line rate on both ports at the same time.

Server administrators who host many virtual machines, run container platforms, or handle large data transfers benefit from the built-in offload engines. Features such as SR-IOV, VXLAN, NVGRE, and RoCE v1 or v2 move common networking tasks away from the CPU, which frees processor cycles for applications and reduces overall latency.

In practical terms, this card suits virtualization clusters, hyperconverged infrastructure nodes, high-throughput storage traffic, and data-intensive workloads such as analytics or backup operations. It supports both UEFI and legacy PXE boot, so automated deployments and remote reinstalls are straightforward.

A typical draw of 11.6 watts keeps power budgets in check, and a one-year limited warranty from HPE backs the hardware. If you need a simple path to faster, more efficient networking inside an HPE Gen10 Plus chassis, this adapter fits smoothly into that role.
