כרטיס רשת PCIe 4.0 x16 כולל שתי יציאות QSFP28 ורוחב פס כולל של עד 100Gbps.
הכרטיס תומך במהירויות של 1G עד 100Gbps לכל יציאה ומאפשר גמישות במגוון סביבות
רשת. כולל תמיכה ב־RDMA להעברת נתונים ישירה וב־SR-IOV לניהול משאבי I/O בסביבות
וירטואליות. מתאים למרכזי נתונים, מחשוב ענן, אחסון נתונים ומערכות מחשוב בעלות ביצועים גבוהים.
When network congestion causes application timeouts in AI training clusters, every microsecond
of latency matters. The LRES1046PF-2QSFP28 PCIe 4.0 x16 dual-port 100G QSFP28 Ethernet
network adapter addresses this by delivering high bandwidth and low latency connectivity
essential for modern data center interconnects.
With a total bandwidth of 100Gbps across two QSFP28 ports, the card ensures efficient data
transmission for big data and cloud computing applications. Supporting speeds from 1G to
100Gbps per port, it provides flexibility for diverse network environments while reducing energy
consumption through IEEE 802.3az Energy Efficient Ethernet standards.
Ideal for data center interconnection, large-scale data storage, and high-performance computing,
this adapter leverages RDMA for direct memory-to-memory transfer without CPU involvement.
SR-IOV enables efficient I/O resource management for virtual machines, making it a robust choice
for scalable cloud infrastructure and enterprise storage solutions requiring reliable, high-speed
networking.
