ADJUNKT Compatible Gigabit ET dual-port server adapter E1G42ETBLK-c

The ADJUNKT E1G42ETBLK-c is a dual-port Gigabit Ethernet server adapter built around the Intel 82576EB controller, delivering reliable, high-throughput networking for servers and workstations. Unlike single-port or desktop-grade NICs, this PCIe 2.0 x4 card provides two independent RJ-45 ports with hardware acceleration features such as VMDq and SR-IOV, making it suitable for virtualized environments and link aggregation scenarios.

Highlights

• Dual Gigabit Ethernet ports with Intel 82576EB chipset
• PCI Express 2.0 x4 interface (compatible with x4, x8, x16 slots)
• Supports 10/100/1000 Mbps data rates
• Full-height and low-profile brackets included
• Advanced features: Jumbo Frames, VLAN tagging, PXE boot, Wake-on-LAN, iSCSI, and link aggregation
• Virtualization support: VMDq and SR-IOV

In daily use

This adapter is designed for server environments where network reliability and throughput are critical. The dual ports allow for teaming or failover configurations, while hardware offloading reduces CPU load during high-traffic operations. The card works with Windows Server, Linux, VMware ESX/ESXi, and FreeBSD, providing broad compatibility across enterprise platforms.
