RDMA, or Remote Direct Memory Access, is a technology used in computer networking to allow direct access to memory between two devices without the need for the intervention of the operating system. Some synonyms for this term include remote memory access, direct memory access over the network, and InfiniBand. In addition, IB verbs and iWARP are two other protocols that use RDMA technology. RDMA is becoming increasingly popular in high-performance computing and data center applications due to its low-latency, high-bandwidth, and low CPU overhead capabilities. As a result, RDMA is an essential component in modern computing systems and plays a crucial role in the functioning of many advanced applications.
