כרטיס רשת PCIe 4.0 x8 כולל שתי יציאות SFP28 במהירות 25Gbps לכל יציאה וברוחב
פס כולל של 50Gbps. הכרטיס מבוסס על בקר Intel E810 וכולל תמיכה בטכנולוגיית ADQ
לניהול תעבורת נתונים. תומך במערכות Windows Server, Linux ו־VMware ESXi.
מתאים למרכזי נתונים, תשתיות ענן, רשתות אחסון ומערכות מחשוב בעלות ביצועים גבוהים.
When network congestion causes application timeouts in AI training clusters or cloud storage
environments, every microsecond of latency matters. The LRES1021PF-2SFP28 addresses
this by providing dedicated application queues that prevent data confusion between workloads,
ensuring predictable performance for critical services.
Built on the Intel E810 controller, this adapter delivers 25Gbps per port over dual SFP28 interfaces,
providing 50Gbps aggregate bandwidth. This high throughput eliminates bottlenecks in high-
performance computing and storage networks, while PCIe 4.0 x8 connectivity ensures maximum
data transfer efficiency to the host system.
Ideal for data centers, cloud computing, and storage networks, the card features scalable ADQ
technology to optimize thread-to-device data paths. With broad OS support including Windows
Server, Linux, and VMware ESXi, it offers a reliable, low-latency solution for enterprise infrastructure
requiring robust 25G connectivity.
