Relationship of Folders, Pools, and Volumes

It is important to know the characteristics of folders and volumes and their relationship to each other and to pools. Some of the characteristics are outlined in the following table.

Folders Volumes
Folders are provisioned within pools, and can contain volumes. A volume can belong to a pool without being part of a folder.
Folder names must be unique within the pool that contains them. Volume names, even those within folders, must be unique across a group.
Pools containing folders can be merged after name conflicts are resolved. However, the folders themselves cannot be merged. Volumes and their clones can be spread across multiple folders. Volumes can be moved across folders in the same pool or in multiple pools.
