IWARP/RDMA iWARP provides converged fabric services with low latency for data centers using Remote Direct Memory Access (RDMA) over Ethernet. The key components of iWARP that ensure low latency are kernel bypass, direct data placement, and transport acceleration. With Intel Data Direct I/O technology, Intel server adapters communicate directly with the processor cache, bypassing the system memory, which reduces latency, increases the system's I/O bandwidth, and lowers energy consumption.
