Pronunciation: [ˈa͡ɪ sˈɜː] (IPA) 
The word "iSER" is spelled with the phonetic transcription /ˈaɪsər/. It is important to note that the "i" in "iSER" is pronounced as a long "i" sound, like the "i" in "ice". The "S" is pronounced as an "s" sound, while the "E" is pronounced as a short "e" sound, like the "e" in "bet". Lastly, the "R" is pronounced as an "r" sound, but it is not emphasized. Overall, "iSER" is pronounced as "eye-suh".
iSER stands for iSCSI (Internet Small Computer System Interface) Extensions for Remote Direct Memory Access (RDMA). It is a computer networking protocol used for transferring data over a network between computers.
The iSER protocol is an extension of the iSCSI protocol that utilizes the capabilities of RDMA technology. RDMA allows data to be directly transferred between the memory of two computers without the need for heavy involvement of the operating system and CPU, resulting in improved performance and reduced latency.
iSER provides a highly efficient and low-latency method for transferring large amounts of data between storage systems and servers. By leveraging the speed and efficiency of RDMA technology, iSER significantly improves the performance of block-level storage access and delivers faster data transfers. This makes it particularly useful in high-performance computing environments, where low latency and high bandwidth are critical.
To establish a connection using iSER, both the server and the client need to have RDMA capabilities enabled and be connected over a network that supports RDMA protocols. The iSER protocol then encapsulates the SCSI commands and data and transfers them over an RDMA-enabled network, eliminating the need for traditional TCP/IP stack processing and associated overhead.
Overall, iSER is a protocol that combines the benefits of iSCSI and RDMA, enabling faster and more efficient data transfers between storage systems and servers, particularly in high-performance computing environments.
