Product Info

Dual-Port 10 Gigabit SFP+ Ethernet Converged Network Adapters Provide Ultimate Flexibility and Scalability in Virtual and Unified Storage Environments

Intel's family of adapters, the Intel® Ethernet Converged Network Adapter X520 with SFP+ connectivity, are the most flexible and scalable Ethernet adapters for today's demanding data center environments. Data center networks are being pushed to their limits. The escalating deployments of servers with multi-core processors and demanding applications such as High Performance Computing (HPC), database clusters, and video-on-demand are driving the need for 10 Gbps connections. Customers require flexible and scalable I/O solutions to meet the rigorous requirements of running mission-critical applications in virtualized and unified storage environments.

Powered by Intel's third-generation 10 GbE network controller, the Intel® Ethernet 82599 10 Gigabit Ethernet Controller, the X520 adapter family addresses the demanding needs of the next-generation data center by providing unmatched features for virtualization, flexibility for LAN and SAN networking, and proven, reliable performance.


  • Intel® 82599 10 Gigabit Ethernet Controller
    Industry-leading, energy-efficient design for next-generation 10 Gigabit performance and multi-core processors.
  • SFP+ Connectivity
    X520 Adapters with SFP+ connections support 10GBASE-SR, 10GBASE-LR and SFP+ Copper Direct Attach physical media.
  • Low-profile
    Enables higher bandwidth and throughput from standard and low-profile PCIe slots and servers.
  • Load balancing on multiple CPUs
    Increases performance on multi-processor systems by efficiently balancing network loads across CPU cores when used with Receive-Side Scaling (RSS) from Microsoft or Scalable I/O on Linux*.
  • iSCSI remote boot support
    Provides centralized storage area network (SAN) management at a lower cost than other iSCSI solutions.
  • Fibre Channel over Ethernet (FCoE) Support
    Includes FCoE Boot and Data Center Bridging.
  • Support for most network operating systems (NOS)
    Enables widespread deployment.
  • RoHS-compliant
    Complies with the European Union directive 2002/95/EC to reduce the use of hazardous materials.
  • Intel® PROSet Utility for Windows* Device Manager
    Provides point-and-click management of individual adapters, advanced adapter features, connection teaming, and virtual local area network (VLAN) configuration.
  • Time Sync (IEEE 1588*, 802.1as)
    Enables networked Ethernet equipment to synchronize internal clocks according to a network master clock; endpoint can then acquire an accurate estimate of the master time by compensating for link latency.
