How VxVM handles storage management

VxVM uses the following types of objects to handle storage management:

Physical objects 

physical disks or other hardware with block and raw operating system device interfaces that are used to store data. 

See "Physical objects" on page 20. 

Virtual objects 

When one or more physical disks are brought under the control of VxVM, it creates virtual objects called volumes on those physical disks. Each volume records and retrieves data from one or more physical disks. Volumes are accessed by file systems, databases, or other applications in the same way that physical disks are accessed. Volumes are also composed of other virtual objects (plexes and subdisks) that are used in changing the volume configuration. Volumes and their virtual components are called virtual objects or VxVM objects.
