HPE P10112-B21 Ethernet 10/25 Gb 2-Port SFP28 Adapter
Overview
The HPE P10112-B21 is a network adapter designed for HPE server platforms, offering two SFP28 ports capable of either 10 Gb/s or 25 Gb/s link speeds. It installs via an OCP 3.0-compliant mezzanine interface (or equivalent adapter slot) and supports full line-rate traffic on both ports, making it suitable for virtualised hosts, storage servers or converged infrastructure requiring high-speed uplinks. With advanced offloads and future-ready link speeds, the adapter allows organisations to deploy at 10 Gb today and seamlessly upgrade to 25 Gb without replacing the card. Its compact form-factor fits certified HPE Gen10 Plus servers and enables efficient dual-port connectivity with minimal expansion slot impact.
