Dual-Port PCIe X4 Gigabit NIC, Intel 82576 Chip Dual RJ45 Ethernet Adapter Support PXE & SR-IOV, Low Profile Bracket for Server PC

This dual-port PCIe X4 gigabit Ethernet network card adopts mature Intel 82576 enterprise-grade chip, providing two isolated 1000Mbps network channels to meet multi-network access requirements of file servers, virtualization hosts, industrial control equipment and monitoring workstations.

It integrates core enterprise functions including PXE network boot for batch equipment deployment and SR-IOV virtualization to allocate independent network resources for virtual machines, effectively improving virtual cluster transmission efficiency. Link aggregation technology realizes bandwidth superposition, while network failover avoids service interruption caused by single cable failure.

Two interchangeable mounting brackets are included to fit conventional ATX rack servers and short-height slim chassis. Optimized PCB shielding layout reduces signal crosstalk and transmission delay; hardware checksum offloading greatly lowers CPU consumption under high concurrent traffic.

The card runs smoothly across mainstream desktop, server and industrial operating systems, supporting jumbo frames and IEEE802.1Q VLAN division. It can work continuously 24 hours a day, an ideal dual-port wired expansion hardware for enterprise IT infrastructure, NAS storage and firewall routing devices.
