Detailed Specifications

HPE  P08442‑B21 10/25 GbE 2‑Port SFP28 Adapter

Overview

The HPE P08442‑B21 is a high‑performance server network adapter designed for modern data‑centre and compute‑intensive environments. It provides two SFP28 ports capable of 10 Gb/s or 25 Gb/s link speeds each, enabling flexible uplink bandwidth and future‑proof connectivity over fibre or DAC cabling. Installed in compatible HPE servers, it enables full line‑rate dual‑port performance, supports large virtualised workloads, high‑throughput storage traffic and converged I/O architectures. Using the SFP28 form‑factor and a mezzanine or PCIe slot interface, the adapter integrates seamlessly with server boards while freeing expansion slots. It is appropriate for hyper‑scale compute nodes, high‑density racks or storage‑accelerated servers requiring dual high‑speed uplinks and advanced offload functionality.
