כרטיס רשת PCIe 4.0 x16 כולל יציאת QSFP28 ומספק מהירות של עד 100Gbps.
הכרטיס מבוסס על בקר Intel E810 ותומך בקצבים 100G, 50G, 25G ו־10G. כולל
תמיכה ב־RDMA, IEEE 1588 PTP וטכנולוגיית ADQ לניהול יעיל של תעבורת הרשת.
תואם גם ל־PCIe 3.0 ו־PCIe 2.0 ומתאים למרכזי נתונים, תשתיות ענן ורשתות אחסון.
When network congestion causes application timeouts in AI training clusters or high-frequency trading
platforms, every microsecond of latency matters. The LRES1019PF-QSFP28 addresses this by providing
dedicated application queues through Intel E810’s ADQ technology, ensuring critical workloads receive
predictable performance without interference from other traffic.
With a PCIe 4.0 x16 interface and a single 100G QSFP28 port, this adapter delivers up to 100Gb/s
throughput, eliminating bandwidth bottlenecks in modern data centers. It supports flexible rate
configuration including 1*100G, 2*50G, 2*25G, and 4*10G, enabling seamless integration into diverse
network infrastructures while maintaining backward compatibility with PCIe 3.0 and 2.0 slots.
Ideal for cloud computing, storage networks, and high-performance computing, the LRES1019PF-QSFP28
leverages Intel E810’s hardware-accelerated packet processing to reduce CPU overhead. Its support for
RDMA (iWARP/RoCEv2) and IEEE 1588 PTP ensures precise synchronization and high-speed data transfer,
making it a robust choice for enterprise-grade network expansion.
