What is RDMA?

RDMA (Remote Direct Memory Access) is a network communication technology derived from DMA (Direct Memory Access). It enables user applications to bypass the operating system kernel (CPU) and directly interact with network interface cards (NICs) for data transmission, delivering ultra-high bandwidth and ultra-low latency. Initially developed for high-performance computing (HPC), RDMA has now become widely adopted in data centers。
