SAN (Storage Area Network) is a high-performance, specialized network designed to provide block-level data storage. It connects servers and storage devices (such as disk arrays or tape libraries) to enable faster, centralized access to storage resources, separate from the regular LAN (Local Area Network) traffic. SANs are typically used in environments where large amounts of data need to be accessed quickly, such as in data centers, enterprise networks, and virtualized environments.
