 - `allowVolumeExpansion`: Allows the volume to be expanded after it has been provisioned.
 - `parameters.type`: Combines multiple physical volumes to create a single logical volume. In a striped setup, data is spread across the physical volumes in a way that distributes the I/O load evenly, improving performance by allowing parallel disk I/O operations.
