High-performance OCP 3.0 dual-port 100GbE network adapter based on Intel E835, supporting up to 200GbE speeds for data centers.
Modern data centers face increasing power density challenges while needing to scale bandwidth for AI training and cloud transfers. Traditional adapters often struggle with latency and energy efficiency in these high-demand scenarios.
The LRES4080PF-2QSFP56 delivers up to 200GbE throughput using dual QSFP56 ports, enabling seamless handling of large data transfers without bottlenecks. Its low-power design consumes a maximum of 16.6W for optical transceivers, significantly reducing system energy costs and environmental impact.
Built on the Intel E835 controller, this OCP 3.0 NIC supports iWARP and RoCE V2 RDMA for fast data exchange in virtualized environments. It is an optimal choice for enterprises requiring reliable, high-speed connectivity with advanced protocol support like IEEE 1588 PTP v2.
Supports speeds up to 200GbE with dual QSFP56 ports for demanding data center workloads.
Based on the Intel E835 chipset for reliable performance and advanced feature support.
Configurable via EPCT to support various port splits including 1x200, 4x50, and 8x25.
Consumes max 16.6W for optical interfaces, reducing energy costs and environmental impact.
Supports RDMA (iWARP/RoCE V2), DPDK, DDP, and IEEE 1588 PTP v2 for low-latency applications.
