The Datasets screen and widgets show information about datasets and zvols, provide access to data management functions, indicate the dataset roles, list the services using the dataset, show encryption status, and list permissions for datasets. The screen focuses on managing data storage, including user and group quotas, snapshots, and other data protection measures.

The Datasets screen shows No Datasets and a Create Pool button until you add a pool and the first root dataset.

Thin provisioning is a storage management technique used to optimize storage utilization and efficiency. It allows administrators to allocate storage capacity dynamically, on an as-needed basis, rather than allocating it all upfront.

Traditional thick storage allocation involves dedicating a specific amount of physical storage space for each zvol upfront, regardless of whether that space is immediately used. This can lead to inefficient use of storage resources and increased costs.
