Fortunately, as data continues to grow exponentially, the selection of data storage technologies has never been more robust. The choice of what storage device to use for which application at a given point in time is a balancing act making trade-offs between frequency of access (performance), cost, and capacity. Storage tiering has become a key strategy that lets you optimize the use of storage resources, save costs and make the best use of storage technology for each data classification. The foundations of tiered storage had their beginnings over 30 years ago when disk, automated tape libraries and advanced policy-based data management software such as (HSM) combined to effectively migrate less-active data to less expensive storage devices.
Tiered storage integrates hardware and storage management software to provide a seamless operation and for customers to realize the huge TCO and ROI economic benefits available from optimized storage implementations. The business case for implementing tiered storage is compelling and becomes increasingly so as storage pools get larger. Today’s storage tiers offer several technologies ranging from ultra-high capacity, low cost storage at one end of the hierarchy to very high levels of performance and functionality and at the other. The non-stop, increasing growth of data will require the continual evolution of new, more advanced approaches to tiered storage and management capabilities.
