The Business Value of Intelligent Tiered Storage
Now, with the rate of storage growth outstripping the rate of its price decline, tiering and storage economics are back on the agenda—still not because they are inherently desired, but because of what they can deliver: namely, lower costs, better business outcomes, and a pragmatic route to cope with massive storage growth. These are the "economics of necessity." Of course, once good tiers and tools that make effective tiering feasible (and the economics compelling) exist, then users also start looking at the "economics of opportunity"—in other words, if tiering is something that can be embraced rather than avoided, then additional value can be sought and overall efficiency can be increased. Tiered storage can move from something that users do because they have to (as little as they can get away with) to something they do because they want to.
