Dual-port 10GBASE-T PCIe x4 network adapter with Intel X550 controller for servers and workstations.
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.
New generation single- and dual-port 10Gbase-T controller with integrated MAC and PHY.
Supports 2.5 and 5.0 GbE over CAT5e cabling for flexible network speeds.
TCP/UDP/IP checksum offloading and TCP segmentation tasks release CPU resources.
Adapter can be bundled into groups for automatic failover and uninterrupted communication.
Supports PCI-SIG SR-IOV and VMDq for optimized virtual machine networking.
Backward compatible with existing 1000BASE-T networks to simplify 10GbE transition.
