WebOct 15, 2024 · Remote Direct Memory Access (RDMA) is a revolutionary technology that enables host devices (devices connected over a network) to read and write data present in their main memory without the CPU’s and the operating system’s involvement. WebiWARP delivers converged, low-latency fabric services to data centers through Remote Direct Memory Access (RDMA) over Ethernet. The key iWARP components that deliver low-latency are as follows: • Kernel Bypass. Removes the need for context switching from kernel-space to user-space • Direct Data Placement.

It enables data to be transferred from a computer’s working memory to the working memory of another system, without burdening the operating systems, cache or CPU in the process. Many products (hardware and software) already support RDMA.

WebRDMA provides both two-sided message passing interfaces like SEND/RECV Verbs as well as one-sided operations such as read, write and two atomic operations (fetch-and-add and compare-and-swap). As noted in prior work [9, 32], one-sided operations are usually more efficient than its two-sided counterpart due to no CPU involvement in the target CPU.
