iSCSI stands for Internet Small Computer Systems Interface. It is a protocol that allows data storage facilities to communicate over a network using the Internet Protocol (IP). By enabling the linking of storage devices over long distances, iSCSI helps organizations manage their data more efficiently and cost-effectively. With iSCSI, servers can access storage resources as if they were directly attached, even if they are located far away. This technology is commonly used in data centers and cloud storage solutions, providing flexibility and scalability for businesses looking to optimize their storage infrastructure.
