HPE684219-B21

FlexFabric 526FLR Dual-Port 10 GbE SFP+ Network Adapter

The HPE684219-B21 FlexFabric 526FLR Network Adapter is a dual-port 10 GbE SFP+ card in FlexibleLOM form factor, engineered for HPE ProLiant servers. Supporting high-speed optical or DAC connectivity, it enables converged networking, iSCSI, and FCoE traffic over a single interface. This adapter delivers exceptional efficiency for virtualized workloads, storage environments, and enterprise compute clusters. Ideal for IT professionals upgrading legacy 1 GbE infrastructure or deploying modern high-bandwidth servers, the 526FLR provides cost-effective throughput, low latency, and multi-protocol flexibility when paired with standard SFP+ transceivers.

Features

Placed in the FlexibleLOM slot of an HPEProLiant Gen8/Gen9 server, this card delivers two independent 10 GbE SFP+ ports via PCIe 2.0 x8 connectivity. It supports 10GBase-X optical and DAC cabling and enables unified use cases such as Ethernet, iSCSI storage, and Fibre Channel over Ethernet (FCoE). Built for converged networking infrastructure, the adapter helps reduce cable complexity while enhancing performance for SAN and LAN traffic. Great for virtualization hosts, storage servers, and converged systems, the 526FLR simplifies deployment and minimizes CPU load with offload support.

Advanced Options

Built for enterprise data centers, the 684219-B21 ensures stable, low-latency throughput across compute and storage networks. With support for converged protocols like iSCSI and FCoE, it eliminates the need for separate HBA or NIC cards,
