Basic volumes

A basic volume is the simplest type of volume, consisting of a copy in a single storage pool.

A basic volume is a volume that has only one physical copy. Basic volumes reside in a single pool on one site. In addition, basic volumes are supported in any system topology and are common to all configurations. A basic volume can be of any type of virtualization: striped, sequential, or image. They can also use any type of capacity savings: thin-provisioning, compressed, or none. Deduplication can be configured with volumes that use different capacity saving methods, such as thin-provisioning. Deduplicated volumes must be created in data reduction pools for added capacity savings. Deduplication is a type of data reduction that eliminates duplicate copies of data. Deduplication of user data occurs within a data reduction pool and only between volumes or volume copies that are marked as deduplicated. Some models or software versions require specific hardware or software to use this function. For more information, see planning data reduction pools and deduplication.
