Implementation and Evaluation of iSCSI over RDMA

iSCSI is an emerging storage network technology that al-lows block-level access to storage devices, such as disk drives, over a computer network. Since iSCSI runs over the ubiquitous TCP/IP protocol, it has many advantages over its more proprietary alternatives. Due to the recent movement toward 10 gigabit Ethernet, storage vendors are interested to see the benefits this large increase in network bandwidth could bring to iSCSI. In order to make full use of the bandwidth provided by a 10 gigabit Ethernet link, specialized Remote Direct Memory Access hardware is being developed to offload processing and reduce the data-copy-overhead found in a standard TCP/IP network stack. This paper focuses on the development of an iSCSI implementation that is capa
