Data centers were only implement Fibre Channel storage area networks (SANs) for past few years, with mainly relying on direct attached storage (DAS). Data consumption rates were awful, with data centers on normally using just 25% to 30% of their hard disk drive capacity

Despite Fibre Channel and IP SAN implementation and the introduction of technologies for instance thin provisioning, storage resource administration, capacity recovery and storage virtualization, storage consumption rates stay at 40% or lower. In fewer terms, IT shops aren't using as a great deal as 60% of their storage capability, wasting power and floor space. With no improved use of storage administration tools, users won't be capable to track utilization and get better with it.

a number of business analysts who think storage utilization at present still averages between 20% and 40%, mostly since thin provisioning and storage management applications with superior reporting capabilities that could point to wasted storage resources aren't being used.
