Extending Intel® Virtualization Technology beyond server virtualization to the network with 

hardware optimizations and off-loads for the rapid provisioning of networks in an agile data center


       PCIe x8 Intel X710 Quad-Port 10G SFP+ Converged adapter is used 710 series implements a PCIe v3.0 x8 host interface, 

which operates at up to 8GT/S or 64Gb/s. It provides complete functionality to support four 10Gb/s ports, the device perform all functions required for transmission and reception as specified in IEEE Std. By providing unmatched features for Server and network virtualization, small packet performance, and low power; the data center is flexible, scalable, and resilient.

       • Interoperability 

       - Multiple speeds and media types for broad compatibility backed by extensive testing and validation.


       - Intelligent offloads and accelerators to unlock network performance in servers with Intel® Xeon® processors.


       - Both Kernel and Data Plane Development Kit (DPDK) drivers for scalable packet processing.

Key Features

      • PCI-Express host interface specification v3.0 x8 and higher

      • Supports the PCI Bus Power Management specification and section 5 of the PCI Express Base Specification
