Figure 5-2 shows the basic concept of a Thin-provisioned volume. Also, you can see the different types of volumes in DRP described in Figure 5-3. You can enhance capacity efficiency for thin-provisioned volumes by monitoring the hosts use  of capacity. When the host indicates that the capacity is no longer needed, the space is  released and can be reclaimed by the DRP. It is redistributed automatically. Standard pools do  not have these functions. In standard pools, thin-provisioned volumes are created as a specific volume type that is  based on capacity savings criteria. These properties are managed at the volume level.  However, in DRP, all the benefits of thin-provisioning are available to all the volumes that are  assigned to the pool. For the thin-provisioned volumes in DRP, you can configure  compression and data deduplication on these volumes, increasing the capacity savings for  the entire pool.  Before describing the different volume types in detail, we will describe the concept of  thin-provisioned volumes again. Chapter 5.
