Overview

LRES1250PF-2QSFP56 is a PCIe x16 Dual-port100G Ethernet Network Adapter independently developed by Linkreal Co., Ltd. . It is equipped with two QSFP56 connectors, supports high-speed fiber transmission, and the physical board size follows the HHHL (Half-Height Half-Length) PCIe add-in card form factor.

LRES1250PF-2QSFP56r can be configured as a 2x100G adapter with Port0 active as 200G and Port1 disabled. This can be configured at run time through firmware.

The LRES1250PF-2QSFP56 features on-chip acceleration for Geneve, VXLAN, and NVGRE tunneling protocols, reducing CPU utilization by up to 90% compared to software-only implementations. It also supports advanced networking technologies such as RoCE, SDN, and NFV, enabling more efficient network management and providing greater flexibility for deploying modern service provider and cloud-scale solutions.

LRES1250PF-2QSFP56 is designed to deliver feature-rich networking solutions in servers for enterprise and cloud-scale networking and storage applications, including high-performance computing, telco, machine learning, storage disaggregation, and data analytics.
