HPE 870823‑001 Ethernet 10/25 Gb 2‑Port 631FLR‑SFP28 Adapter
Overview
The HPE 870823‑001 is a dual‑port network adapter designed for modern high‑throughput server environments. Each port supports both 10 Gb/s and 25 Gb/s link speeds via an SFP28 interface, offering flexible uplink bandwidth to match evolving network infrastructures. The adapter installs in a 631 FLR mezzanine slot on certified server platforms (such as HPE ProLiant models) and uses a PCI Express architecture beneath the mezzanine interface to deliver full throughput. It is suitable for virtualised hosts, storage and compute nodes needing dual high‑speed links without consuming multiple expansion slots. Features include support for advanced offloads (such as RDMA over Converged Ethernet), VXLAN/NVGRE tunnelling, jumbo frames up to ~9.2 KB, and full dual‑port operation at line rate. As networks transition from 10 Gb to 25 Gb, this adapter provides future‑proof connectivity while preserving server slot real‑estate and cabling infrastructure flexibility.
