Intel® 82576EB Gigabit Ethernet Adapter

Low-Power, Small-Footprint, Single-Port Gigabit Network Connectivity with Advanced Performance Features


The Intel Gigabit Dual Port Server Adapter, and features 10/100/1000 Mbps self-configuration for compatibility with mixed-speed 

network infrastructures.

The dedicated input/output (I/O) bandwidth of PCIe ensures priority performance on each port—without bus sharing—for Gigabit 

Ethernet connectivity in Category-5 networks, as well as a low-profile design, which improves server throughput and rack density 

at the same time. Intel Gigabit Dual Port Server Adapters are optimized for virtualized environments, supporting multiple queues, 

alleviating I/O bottlenecks between virtual machines. Additionally, the Intel Gigabit Quad Port Server Adapter enables Intel® I/O 

Acceleration Technology1 (Intel® I/OAT) with support for Intel® QuickData for faster I/O processing on the new Quad-Core and 

Dual-Core Intel® Xeon® processor-based servers.

Key Feature

• Dual Port 10/100/1000Mbps adapters

• PCI Express V2.0 (5GT/s) X4 Lanes

• RJ45 Connectivity

• Network Virtualization

• Improves performance and throughput by reducing the I/O overhead due to the software virtualization layer

• Data Plane Development Kit (DPDK) support

• Simple Network Management Protocol (SNMP) and Remote Network Monitoring (RMON) statistic counters

• Low profile and full-height bracket
