LRES1019PF-QSFP28 is a PCI express v4.0 x16 single-port 100G ethernet network adapter developed by Linkreal Co., Ltd. on the basis of the Intel chip. It is supplemented by the expansion function of hardware acceleration data packet processing, and the application queue technology is introduced. This technology can realize the NVMe support of Fabric TCP. It also has selective support for the iWARP and RoCEv2 functions of RDMA. This adapter can at the same time, it is backward compatible with PCIe v3.0 & v2.0. The adapter card achieves a dual-port bidirectional communication transmission rate with a theoretical throughput of 400GB on a PCI express v4.0 x16 bus.

The ethernet optical fiber network card with independent intellectual property rights (LRES1019PF-QSFP28) launched by Shenzhen Lianrui Electronics Co., Ltd., the network card adopts the application queue technology function to ensure that each application can request its own queue. That is to say, the data between each other is no longer confused, with an interface speed of up to 100Gbps, which can be widely used in data center services, cloud computing, storage and other network equipment that can handle various workloads with high throughput, and combined in actual operation The use of program queues can reduce application latency and increase throughput.

The fiber optic network card provides scalable ADQ technology to improve the performance scalability and predictability of critical workloads by dedicating specific resources to critical workloads. ADQ uses an optimized application thread to device data path to implement application-specific data control, information and rate limiting functions.
