כרטיס רשת PCIe 3.0 x8 כולל יציאת QSFP+ ומספק מהירות תקשורת של עד 40Gbps.
הכרטיס מבוסס על בקר Intel XL710 ותואם גם לחריצי PCIe x16. כולל האצת חומרה
ותמיכה ב־DPDK להפחתת עומס מהמעבד ולניהול יעיל של תעבורת הרשת. תומך ב־SR-IOV
וב־VXLAN ומתאים למרכזי נתונים, תשתיות ענן ורשתות אחסון מתקדמות.
When network congestion causes application timeouts in AI training clusters or high-frequency
trading platforms, every microsecond of latency matters. The LREC9901BF-QSFP+ addresses
this by delivering consistent 40Gbps throughput, ensuring that data-intensive workloads never
stall due to I/O bottlenecks in demanding enterprise environments.
Built on the Intel XL710 controller, this adapter features a PCIe 3.0 x8 interface compatible with
x16 slots, providing robust bandwidth for heavy traffic. With hardware acceleration for TCP/UDP/IP
checksum offloading and support for DPDK, it significantly reduces CPU overhead, enabling servers
to handle more virtual machines and containerized applications efficiently without performance
degradation.
Ideal for data centers, cloud computing infrastructure, and high-end storage networks, the
LREC9901BF-QSFP+ leverages Intel’s proven silicon for reliability. Its support for SR-IOV and
network virtualization protocols like VXLAN makes it a versatile choice for modern software-defined
networks, offering enterprises a scalable and efficient connectivity solution.
