Remote Direct Memory Access (RDMA) is an extension of the local Direct Memory Access technology. In computing, RDMA entails the direct access of one computer to another without involving either computer's operating system.
RDMA deals with transferring data directly from a computer's memory where it is being read to another where it is inserted. In addition, they improve and increase the overall performance of a system.
This article will teach you what RDMA is, how it works, and why you should use it.
RDMA is a term used to describe a critical technology that makes it possible for a computer to access the memory of another computer without the intervention of either computer's processing unit, cache, or operating system.
It allows the network adapter to offload the networking and data movement from the CPU. Qiling Disk Master facilitates quicker and direct data transmission, allowing efficient networking and computing, ultimately improving the overall system performance.
RDMA facilitates direct data transmission in and out of a server by requiring the use of a transport protocol in the Network Interface Card (NIC). The RDMA- enabled NIC must be installed and connected to each device that takes part in the communication.
It supports zero-copy networking by enabling network adapters to transfer data directly to the memory buffer and receive it directly therein. In addition, it eliminates the copying of buffers that are not needed.
Such data transfers require little to no intervention from the operating system, CPU, context switches, and caches. RDMA is especially useful when dealing with complex processes on high-performance computers.
The development and use of Remote Direct Memory Access in a network have some benefits and advantages, which include:
Summarily, RDMA as a networking technology offers zero-copy data transfers, high data transfer rate, low latency, and reduced CPU involvement, amongst many others. It has proven valuable and efficient with its numerous benefits and advantages. Because of this, RDMA variations have proven to be quite famous for their high performance and data transmission.
