Which of the following is NOT a function of SAN?

The correct answer highlights that enabling personal file sharing is not a primary function of a Storage Area Network (SAN). SANs are primarily designed to provide block-level storage and connect servers to pools of storage via high-speed networking. Their main functions include consolidating storage resources, offering high-speed data access, and enhancing the efficiency of data backup and recovery processes.

Unlike file sharing systems that typically cater to end-user environments, allowing personal file sharing focuses on enabling individuals to share files directly between users or personal devices. This kind of functionality aligns more with network file systems (like NAS - Network Attached Storage), which is designed for file-level data storage and sharing rather than the block-level architecture that SANs utilize.

Thus, while SANs excel in high-speed data transfer and efficient backup solutions, they do not inherently support the personal file-sharing capabilities often associated with other storage solutions.
