iSER (iSCSI Extensions for RDMA)

iSER, or iSCSI Extensions for RDMA, is a technology that enhances data transfer over networks by combining two key protocols: iSCSI and Remote Direct Memory Access (RDMA). iSCSI allows storage devices to communicate over IP networks, while RDMA enables fast data transfers by allowing devices to access memory directly, bypassing the CPU. iSER improves the performance of iSCSI by leveraging RDMA, resulting in lower latency and higher throughput. This combination is particularly beneficial in data centers and cloud computing environments where quick and efficient data storage access is crucial.
