How much is it costing your IT department to provide instant availability to all data regardless of value? Traditionally, all data has been treated equally, causing overspending on relatively low-value data assets and allowing it to hog the same costly storage space as high-value business data. It is possible to make a big dent in storage expenses with a tiered-storage approach; this requires the matching of relative data value against its associated storage cost. Simply by classifying data according to business worth and safeguarding each type of dataset at a level appropriate to its business importance, a lower-cost storage infrastructure can be engineered that also improves administration and functionality.
