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.

Key Features

  • Two SFP28 ports supporting 10 Gb/s and 25 Gb/s link speeds.

  • PCIe form‑factor adapter for server uplinks and NIC upgrades.

  • Supports link‑aggregation, VLAN tagging and jumbo‑frame networking.

  • Designed for HPE ProLiant/Synergy servers in high‑density compute or storage nodes.
