RDMA (Remote Direct Memory Access) technology, as a crucial solution for high-performance network communication, is playing an increasingly important role in data centers, high-performance computing, distributed storage, and other fields.</p> <p>RDMA technology achieves direct memory access between applications and network adapters by bypassing the operating system kernel, significantly reducing latency, improving throughput, and reducing CPU utilization. This article will provide an in-depth exploration of RDMA technology&rsquo;s core principles, main protocol implementations, and practical production use cases.</p>
