It has become a standard data reduction feature for many backup and archiving products and is becoming increasingly popular on primary storage. The driving force of this phenomenon is quantifiable cost savings, from having to buying fewer disks to reducing annual support costs, to reducing storage management-related operation costs.

Servers are a concern, but successful virtualization deployments depend on storage. Storage protects the state of a virtual machine, retains snapshots, and helps users access data in a shared application. Due to these features, availability, and performance factors, we have a high demand for the storage infrastructure.
