(640FLR‑SFP28) Dual‑Port 10/25 GbE FlexibleLOM Gigabit Ethernet Adapter Refurbished

The HPE 817747‑001 640FLR‑SFP28 adapter is a high‑performance, dual‑port FlexibleLOM network interface card that supports both 10 GbE and 25 GbE speeds via SFP28. Powered by the Mellanox ConnectX‑4 Lx chipset, it supports up to 50 Gbps per port (100 Gbps aggregate) for virtualization hosts, database servers, and high‑speed application environments. Compatible with Gen9 and Gen10 HPE ProLiant and Apollo servers, this refurbished card delivers reliable throughput, advanced offload features, and future‑ready flexibility at a competitive price.

Features

This adapter slots into the dedicated FlexibleLOM bay to free up PCIe lanes for other devices, providing efficient internal routing and improved airflow. Each port auto-negotiates between 10 GbE and 25 GbE depending on connected transceivers, adapting smoothly in mixed‑speed environments. It supports jumbo frames up to 9.2 KB, ensuring large data payloads are transmitted efficiently. Designed for modern virtualized infrastructure, it also includes RDMA (RoCE v2), VXLAN/NVGRE tunneling, and DPDK offload support reducing CPU overhead while maintaining high throughput

Advanced Options

Built with enterprise-grade networking in mind, this adapter delivers high reliability in dense server environments. The robust ConnectX‑4 Lx controller ensures efficient packet processing with minimal latency while supporting virtualization acceleration technologies such as SR‑IOV,
