OCP3.0 Dual-Port 25G Ethernet Network Adapter

LRES4150PF-2SFP28 is a high-performance dual-port 25G PCIe 3.0 x16 Ethernet adapter, independently developed by Linkreal Co., Ltd. based on the MT28808A0 controller chip. Featuring two SFP28 optical ports, it supports up to 25Gbps per port for high-speed optical transmission. Fully compliant with OCP 3.0 mechanical specifications and designed in a compact Small Form Factor (SFF), it is ideal for space-constrained data center deployments. The adapter supports a comprehensive set of hardware offload features, including TCP/UDP/IP stateless offload, checksum offload, LSO, LRO, and RSS with encapsulation support.

These offloads significantly reduce CPU utilization and improve network and system performance. With built-in Open vSwitch (OVS) hardware offload, the LRES4150PF-2SFP28 delivers high packet throughput while minimizing CPU usage, helping telecom and cloud data centers enhance infrastructure efficiency and reduce operating costs. The adapter also supports RoCE (RDMA over Converged Ethernet), providing ultra-low latency, high bandwidth, and improved application performance for latency-sensitive workloads. Designed for enterprise and cloud-scale environments, the LRES4150PF-2SFP28 is well-suited for HPC, telecommunications, AI/machine learning, cloud data centers, and large-scale data analytics, delivering a scalable, efficient, and feature-rich networking solution for next-generation servers.
