LUN Definition - What is a logical unit number (LUN)?
WEBLUNs are used to identify SCSI devices, such as external hard drives, connected to a computer. Each device is assigned a LUN, from 0 to 7, which serves as the device's unique address. LUNs can also be used for identifying virtual hard disk partitions, which are used in RAID configurations.
