LOGICAL UNIT NUMBER Meaning and
Definition
-
Logical Unit Number (LUN) refers to a unique identifier that is assigned to a logical unit within a storage area network (SAN), typically a disk drive or array. It serves as a means of identifying and accessing individual storage units within a larger SAN environment.
A LUN is a virtual representation of a physical storage device that enables efficient data management and sharing. It allows multiple servers or host systems to access the shared storage resources in a controlled manner. Each LUN is given a distinct number, enabling it to be recognized and addressed through the SAN infrastructure.
The purpose of assigning a LUN is to allocate storage resources to specific devices while maintaining segregation and efficient utilization. It provides a layer of abstraction between the storage system and the connected hosts, allowing storage to be provisioned, managed, and accessed independently. By mapping a LUN to a logical disk or a specific application, it enables logical connectivity between the host and the storage device.
LUNs play a vital role in facilitating data management and storage virtualization. They enable efficient implementation of features like data replication, snapshots, and thin provisioning. Moreover, LUNs aid in simplifying storage administration tasks by providing a standardized and scalable approach to managing storage resources across the SAN architecture.
In summary, a Logical Unit Number (LUN) is a unique identifier allocated to a logical unit within a storage area network. It enables efficient access and management of storage resources and serves as a virtual representation of a physical storage device.
