Research shows that achieved by most companies is 40% or lower. That means buyers are acquiring more capacity than they really need and the very existence of that extra capacity requires more space apond cooling.

Furthermore, the traditional method of provisioning leads to increased management workloads due to the fact that the extra but unused capacity still needs to be monitored and managed. If reach their capacity limits and IT managers have to re-provision capacity, complex management tasks can be involved. More management requires more human resources, further driving up costs associated with storage management.
Additionally, if an application is taken offline to reprovision capacity, it is then unable to serve business needs and can lead to revenue loss.
Thin provisioning provides a way to address these limitations. By automatically allocating system capacity to applications as needed, thin provisioning technology can help achieve up to 90% storage utilization, while at the same time significantly reducing .
