Intel® Gigabit ET2 Multi-Port Server Adapters

Intel® Gigabit ET, ET2, and EF Multi-Port Server Adapters

The Intel® Gigabit ET and EF Multi-Port Server Adapters are Intel's third generation of PCIe GbE network adapters. Built with the Intel® 82576 Gigabit Ethernet Controller, these new adapters showcase the next evolution in GbE networking features for the enterprise network and data center. These features include support for multi-core processors and optimization for server virtualization.

Product information

Features and benefits

Intel® 82576 Gigabit Ethernet Controller
  • Industry-leading, energy-efficient design for next-generation Gigabit performance and multi-core processors
Low-profile
  • Enables higher bandwidth and throughput from standard and low-profile PCI Express* slots and servers
iSCSI remote boot support
  • Provides centralized storage area network (SAN) management at a lower cost than competing iSCSI solutions
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 from Microsoft or Scalable I/O on Linux*
Compatible with x4, x8, and x16 standard and low-profile PCI Express* slots
  • Allows each port to operate without interfering with the other
Multi-port design
  • Enables dual- or quad-port operation in almost any PCI Express server slot, except x1 slots
Support for most network operating systems (NOS)
  • Enables widespread deployment
RoHS-compliant1
  • Compliant with the European Union directive 2002/95/EC to reduce the use of hazardous materials
Intel® PROSet Utility for Microsoft Windows* Device Manager
  • Provides point-and-click management of individual adapters, advanced adapter features, connection teaming, and virtual local area network (VLAN) configuration
Virtual Machine Device Queues (VMDQ)
  • Off loads the data sorting functionality from the Hypervisor to the network silicon, thereby improving data throughput and CPU usage
PC-SIG SR-IOV Implementation
  • Provides an implementation of the PCI-SIG standard for I/O Virtualization. The physical configuration of each port is divided into multiport virtual ports. Each virtual port is assigned to an individual virtual machine directly by bypassing the virtual switch in the Hypervisor, resulting in near native performance
