Dual Port 40GbE QSFP+ PCIe X8 Internal Wired Network Card Intel XL710-T2 for Server HPC Storage Stock

Engineered for modern infrastructure demands, the Lekuo PL71F21 leverages the proven architecture of the Intel XL710 series to deliver unmatched 40G connectivity. Each of its two QSFP+ ports supports full-duplex 40Gbps speeds, enabling up to 80Gbps aggregate bandwidthideal for server-to-server communication, storage traffic, or virtual switch uplinks.

Advanced hardware offloads including SR-IOV and VMDq allow efficient VM density without CPU bottlenecks. Network virtualization protocols like VXLAN and NVGRE are processed directly on the card, while storage workloads benefit from native iSCSI and FCoE offloadaccelerating SAN performance without additional HBAs.

For mission-critical environments, the PL71F21 supports Data Center Bridging (DCB/DCB-X), Priority Flow Control (PFC), and Enhanced Transmission Selection (ETS) to guarantee lossless, predictable latencyessential for financial trading or real-time analytics. Jumbo frames up to 9.5KB further optimize throughput.
