Quad-port 25G SFP28 network adapter based on Intel E810 for cloud and communication.
When AI training clusters and cloud servers face network congestion, every microsecond of latency impacts application throughput. The LRES1023PF-4SFP28 addresses this by providing four dedicated 25Gbps SFP28 ports, ensuring consistent high-bandwidth connectivity for demanding workloads.
Built on the Intel E810 controller, this PCIe 4.0 x16 adapter delivers up to 100Gbps aggregate bandwidth. Features like Application Device Queuing (ADQ) reduce CPU overhead by accelerating protocol-specific traffic, while iWARP and RoCE v2 support enable low-latency RDMA connections essential for modern cloud storage targets.
Ideal for data centers and 5G base stations requiring precise clock synchronization via IEEE 1588 PTP v2. The Intel E810 chipset ensures superior packet processing efficiency compared to previous generations. Choose the LRES1023PF-4SFP28 for scalable, high-performance networking infrastructure.
