Explanation:
Volume Managers
Volume managers allow system administrators to perform operations on their physical devices at the operation-system level. Volume managers are typically used to provide flexibility that is not inherent in the file system or the storage system.
The operations commonly supported by volume managers fall into several categories:
1. Partitioning of LUNs into smaller logical devices
2. Aggregation of several LUNs into a larger logical device in order to provide a larger logical device
3. Striping of data across several LUNs in order to distribute I/O across many disks A volume striped across LUNs where the LUNs themselves are striped across disks is also known as a plaid. {Page 14, CLARiiON Fibre Channel Storage Fundamentals, 10/31/2003)
