LRES4160PF-2QSFP56 is a 200GbE PCIe 4.0 x16 Ethernet network adapter featuring two QSFP56 optical ports, with each port supporting up to 200Gbps high-speed optical transmission. It adopts a PCIe 4.0 x16 interface to provide high-bandwidth, low-latency data transfer and complies with the OCP 3.0 small form factor (SFF) design specification.
The adapter supports TCP/UDP/IP stateless offload, LSO, LRO, checksum offload, and RSS (including RSS for encapsulated packets), offloading packet processing tasks to reduce CPU load and improve network performance. RDMA support delivers low latency and high performance, with end-to-end packet-level flow control enhancing enterprise-class RDMA networking.
LRES4160PF-2QSFP56 is designed for scalable enterprise and cloud-scale networking and storage applications, including high-performance computing, telecommunications, machine learning, and data analytics.
