כרטיס רשת PCIe 3.0 x4 מבוסס על בקר Intel X550 וכולל שתי יציאות RJ45. תומך במהירות
העברת נתונים של עד 10Gbps וב־10GBASE-T למרחק של עד 100 מטר באמצעות כבלי Cat6A.
כולל האצת חומרה עבור TCP/UDP Checksum ותמיכה ב־PXE Boot וב־SR-IOV. מתאים
ליישומי שרתים, אחסון ארגוני וסביבות מחשוב ענן.
When legacy cabling limits data center upgrades, transitioning to 10GbE without replacing
infrastructure becomes critical. The LREC9812BT network adapter solves this by delivering
high-speed connectivity over existing copper cabling.
Based on the Intel X550 controller, this dual-port card supports 10GBASE-T at up to 100m
on Cat6A cabling, enabling seamless migration from 1G networks. With PCIe v3.0 x4 interface
providing 8.0 GT/s bandwidth, it eliminates I/O bottlenecks in virtualized environments while
reducing CPU load via TCP/UDP checksum offloading.
Ideal for multi-network server applications, the adapter supports PXE boot and SR-IOV for
efficient resource allocation. This Intel X550-based solution ensures reliable, low-latency
performance for enterprise storage and cloud computing workloads.
