Intel® 82599EN 10 Gigabit Ethernet Adapter

Transforming the data center through a reliable and unified 10GbE network

Two versions are available

        • 82599ES — Dual-port serial 10 GbE backplane interface for blade implementations 

           (includes the 82599EB SKU functionality plus KR and SFI interfaces).

        • 82599EN — Single-port serial 10 GbE SFI interface for blade implementations.


        • PCI Express* 2.0, Dual port 10 Gigabit Ethernet controller  deliver the performance that demanding applications require.

        • Industry-leading product innovations for I/O virtualization that are ideal for the dynamic data center.

        • Unified networking support simplifies the network infrastructure by allowing LAN, SAN, and IPC traffic to share the same

           data center fabric.

        • Energy-efficient design with integrated SFI/KR PHYs that creates new opportunities for Blades and LAN-on-motherboard 

           (LOM) solutions.

        • High-volume stable architecture with broad operating system support.

        • Advanced features such as Receive Side Coalescing, Intel® Ethernet Flow Director, and support for PCI Express* 2.0 help 

           deliver new levels of 10GbE performance

        • Intel® Virtualization Technology 1 for Connectivity (Intel® VT-c) delivers industry-leading I/O virtualization capabilities 

           that provide flexibility, scalability and mobility

        • Advanced unified networking capabilities, including support for lossless Ethernet, iSCSI acceleration, NAS, and Fibre Channel 

           over Ethernet (FCoE) offloads help consolidate data center networks onto a single Ethernet fabric
