כרטיס רשת PCIe 3.0 x8 כולל שתי יציאות QSFP+ במהירות 40Gbps לכל יציאה.
הכרטיס מבוסס על בקר Intel XL710 ומיועד לתקשורת ברוחב פס גבוה בסביבות שרתים.
כולל האצת חומרה להפחתת עומס מהמעבד ותמיכה ב־SR-IOV וב־VXLAN לווירטואליזציית
רשת. מתאים למרכזי נתונים ולתשתיות ענן הדורשות קישוריות 40G יציבה.
When network congestion causes application timeouts in AI training clusters, every microsecond
of latency matters. The LREC9902BF-2QSFP+ network adapter addresses this by providing
dedicated 40G throughput for data center environments.
Based on the Intel XL710 controller, this dual-port QSFP+ card delivers 40000MbE per port via
PCIe v3.0 x8 lanes, eliminating I/O bottlenecks in high-performance servers. Hardware acceleration
offloads TCP/UDP/IP checksums from the host CPU, enabling higher virtualization density and
reduced server load.
Ideal for IDC rooms and cloud infrastructure, it supports SR-IOV and VXLAN for flexible network
virtualization. Unlike generic alternatives, the Intel XL710 foundation ensures broad OS compatibility
and proven reliability for enterprise deployments requiring sustained 40G bandwidth.
