74 IBM System Storage DS3500: Introduction and Implementation Guide
3.5.1 Planning for systems with LVM: AIX example
Many modern operating systems implement the concept of a Logical Volume Manager (LVM)
that can be used to manage the distribution of data on physical disk devices.
The Logical Volume Manager controls disk resources by mapping data between a simple and
flexible logical view of storage space and the actual physical disks. The Logical Volume
Manager does this by using a layer of device driver code that runs above the traditional
physical device drivers. This logical view of the disk storage is provided to applications and is
independent of the underlying physical disk structure.
