כרטיס רשת PCIe 3.0 x8 כולל ארבע יציאות SFP+ במהירות 10Gbps לכל יציאה וברוחב
פס כולל של 40Gbps. הכרטיס מבוסס על בקר Intel XL710 ותומך ב־SR-IOV וב־DPDK
לסביבות וירטואליות. כולל תמיכה ביתירות ובמעבר בין יציאות במקרה של תקלה. צריכת
החשמל היא 7.4W ומתאים לתשתיות ענן, ניתוח Big Data וסביבות שרתים.
When network congestion causes application timeouts in AI training clusters, every microsecond of
latency matters. The LREC9804BF-4SFP+ Ethernet network adapter addresses this by providing
flexible connectivity for virtualized server environments.
Featuring four 10G SFP+ ports on a PCIe 3.0 x8 interface, this card delivers 40Gbps aggregate
bandwidth, eliminating I/O bottlenecks in multi-tenant servers. With 7.4W power consumption and
support for SR-IOV and DPDK, it reduces CPU overhead while enabling efficient traffic distribution
across processor cores.
Ideal for cloud computing and big data analytics, this Intel XL710-based adapter ensures uninterrupted
operation through port failover and redundancy. It simplifies deployment in mission-critical infrastructure
requiring high throughput and low latency.
