Backed up, archived, and space-managed files are stored in groups of volumes called storage pools. The data on these primary storage pools can be backed up to copy storage pools for disaster recovery purposes. Because each storage pool is assigned to a device class, you can logically group your storage devices to meet your storage management needs.
You can establish a hierarchy of storage pools. The hierarchy may be based on the speed or the cost of the devices associated with the pools. TSM migrates client files through this hierarchy to ensure the most efficient use of a server's storage devices.
When defining or modifying a storage pool, you can specify any or all of the following:
You manage storage volumes by defining, updating, and deleting volumes, and by monitoring the use of server storage. You can also move files within and across storage pools to optimize the use of server storage.
For more information about storage pools and volumes and taking advantage of storage pool features, see Chapter 7, Managing Storage Pools and Volumes.
