Description: LUN, or Logical Unit Number, is a unique identifier assigned to a logical unit in a storage system. This concept is fundamental in storage management, as it allows operating systems and applications to efficiently identify and access storage devices. A LUN can represent a disk partition, a complete disk, or a set of disks in more complex storage configurations, such as in storage area networks (SAN). LUNs are used in various platforms, enabling the management of storage resources. The assignment of a LUN allows system administrators to manage storage more granularly, optimizing performance and data availability. Additionally, LUNs are essential in virtualization, where multiple virtual machines can share the same physical storage resource, each accessing its own LUN. In summary, the LUN is a critical component in modern storage architecture, providing a structured method for identifying and managing logical units in complex IT environments.
