HPE 840139-001 25Gb 2-port SFP28 Network Adapter HPE

HPE 840139‑001 Ethernet 10/25Gb 2‑Port 640FLR‑SFP28 Adapter

Overview

The HPE 840139‑001 is a dual‑port network adapter in FlexibleLOM (FLR) form‑factor, designed for select HPE ProLiant Gen9 and Gen10 rack servers. It supports 10 Gb/s and 25 Gb/s Ethernet connectivity via SFP28 interfaces, making it suitable for high‑bandwidth uplinks, virtualised servers and storage‑traffic offload. The adapter installs directly into the server’s dedicated FLR slot, conserving standard PCIe slots and simplifying upgrade paths. It supports advanced features including IPv6, jumbo frames, VXLAN/NVGRE tunnel offload and RoCE for latency‑sensitive workloads. The device is tailored for data‑centre compute servers where 25 Gb bandwidth is becoming the norm.
