Intel® Ethernet Server Adapter 82576EB

Quad-port Gigabit Ethernet server adapters, designed with performance enhancing features and new power management technologies

The new Intel® Ethernet Server Adapter 82576EB family builds on Intel’s history of excellence in Ethernet products. Intel continues its market leadership with this new generation of PCIe* GbE network adapters. Built 

with the bridgeless Intel® Ethernet Controller 82576EB, these adapters represent the next step in the Gigabit 

Ethernet (GbE) networking evolution for the enterprise and data center by introducing new levels of performance through industry-leading enhancements for both virtualized and iSCSI Unified Networkingenvironments. 

This new family of adapters also includes new power management technologies such as Energy Efficient Ethernet 

(EEE) and DMA Coalescing (DMAC).

Key Features

• Halogen-free dual Gigabit Ethernet adapters with copper interface options

• Innovative power management features including Energy Efficient Ethernet (EEE) and DMA Coalescing for

  increased efficiency and reduced power consumption

• Flexible I/O virtualization for port partitioning and quality of service (QoS) of up to 32 virtual ports

• Scalable iSCSI performance delivering cost-effective SAN connectivity

• High-performing bridgeless design supporting PCI Express* Gen 1.1 2.5GT/s

• Reliable and proven Gigabit Ethernet technology
