Keep critical server traffic moving with a dual-port SFP+ adapter designed for 10 Gb/s fiber connectivity. The AddOn 90Y6456-AO comparable network interface uses Intel 82599 silicon and a PCI Express 2.0 x8 host interface to deliver the bandwidth required for storage access, virtualization, backup traffic, and east-west data flows. Open SFP+ ports give you the flexibility to match the transceiver and fiber type to the deployment, whether the link runs over single-mode or multi-mode fiber. That matters in mixed infrastructure, where distance, optics, and switch compatibility can vary from rack to rack. The plug-in card form factor fits server expansion slots cleanly and is suited to environments where stable, repeatable performance matters more than commodity pricing. For teams standardizing on proven 10 GbE infrastructure, this adapter offers a practical path to higher throughput without changing the server platform. It is a strong fit for data center upgrades, network segmentation, and applications that need consistent fiber performance over long service cycles.
