Single-port 100G QSFP28 NIC based on Intel E810 for high-throughput data center workloads.
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.
Delivers up to 100Gb/s throughput for wide range of workloads in modern data centers.
