מערכות מחשוב מתקדמות ותחנות עבודה.
Network bottlenecks in high-performance computing often stem from limited bandwidth or
excessive CPU overhead during data processing. The LREC9802BT addresses these
challenges by providing robust 10G connectivity directly over copper cabling, eliminating
the need for expensive fiber optics while maintaining high throughput.
Built on the Intel X540 controller, this dual-port adapter delivers 10Gbps per port with full
hardware offloading for TCP/UDP/IP checksums and TCP segmentation. This significantly
reduces host CPU usage, enabling servers to handle more concurrent applications without
performance degradation.
Ideal for enterprise servers, AI training clusters, and high-end workstations, the card
supports advanced features like SR-IOV, VMDQ, and Jumbo Frames. Its compatibility
with PCIe x8 and x16 slots ensures flexible deployment, offering a reliable, cost-effective
upgrade path for existing infrastructure.
