What is RDMA?The access of one computer's memory by another in a network without the involvement of any computer's operating system, processor, or cache is referred to as RDMA. Because many resources are freed up, it aids in improving system throughput and performance.On a remote machine, read and write operations can be performed without being interrupted by the CPU of that machine. The data transfer rate is increased, and networking latency is reduced, thanks to this technology. It uses zero-copy networking for transferring data directly into system buffers by enabling network adapters.RDMA was earlier used only in high-performance computing (HPC) ... Read More
