Detailed Specifications
HPE P24838-B21 10/25 GbE 2-Port SFP28 Adapter
Overview
The HPE P24838-B21 is a dual-port network interface adapter designed for high-bandwidth server uplinks in virtualised and storage-traffic-heavy environments. It delivers up to 25 Gb/s per port via SFP28 connectivity, with backward compatibility at 10 Gb/s speeds. The adapter interfaces via a PCIe slot in certified servers, enabling ~50 Gb/s aggregate throughput. It is suited for deployment in rack-mount servers at the edge, compute-node or hyper-converged infrastructure layer where low-latency, consolidated I/O is required. The module supports advanced features such as link-aggregation (LACP), VLAN-tagging, jumbo-frames and is certified for use in HPE ProLiant and Synergy server platforms.
