What is the first level in the hierarchy of VPLEX volumes?

The first level in the hierarchy of VPLEX volumes is the Storage Volume. In the context of VPLEX, a Storage Volume represents the physical storage from which data is accessed and used. This volume serves as the foundational component that holds the actual data on the underlying storage system.

Understanding this structure is crucial because it indicates that all other volume types, including Virtual Volumes and Extents, build upon the concept of the Storage Volume. For example, Virtual Volumes are essentially logical representations created from one or more Storage Volumes, and Extents are segments of storage within a Storage Volume. Therefore, recognizing the Storage Volume as the first tier helps in grasping the interrelationships between different volume types in the VPLEX architecture and managing data more efficiently across multiple storage systems.
