HPE Ethernet 10/25Gb 2-port SFP28 Adapter

The HPE P26262-B21 is an Ethernet adapter designed for ProLiant Gen10 Plus servers. It provides two SFP28 ports that can run at 10 or 25Gb, so you can start with today’s bandwidth requirements and scale up when traffic grows. Because the adapter sits in a PCIe Gen3 x8 slot, the server can push data through the network without the link becoming a bottleneck.

Inside the card, the Broadcom BCM57414 controller handles packet processing and offloads tasks that would otherwise tax the CPU. Features such as RDMA and RoCE v1 or v2 let storage traffic and distributed applications move between servers with minimal latency. Support for SR-IOV and network virtualization standards, including VXLAN and NVGRE, makes it simpler to carve out isolated networks for virtual machines while keeping performance strong.

The card also contributes to a secure server build. Secure boot helps verify firmware integrity at power-on, reducing the attack surface in environments that demand strong security controls. Typical power draw is about 9.1 watts, which helps keep overall system power budgets predictable.

This adapter fits naturally in data centers that host virtualization clusters, software-defined storage nodes, or high performance computing workloads that rely on fast east-west traffic. Administrators who need a straightforward upgrade path from 10Gb to 25Gb Ethernet will appreciate the flexibility offered by the dual SFP28 design.
