We survey how the major vendors leverage solid-state to implement effective storage tiering. Technology developments follow a predictable evolution. New functionality starts as an "exclusive" competitive feature offered by one or just a few companies, followed by vigorous industry competition of highly differentiated offerings, and finally inclusion in the "baseline" feature set of most products. Storage tiering, and more specifically automated storage tiering, has become a baseline element. Even so, significant differentiation gives storage managers a mouth-watering choice when it comes to evaluating competing solutions. This differentiation is particularly important to those organizations that seek best-of-breed products, where tiered data storage is a significant requirement. All tiering offerings have certain things in common. First, and at a minimum, the array hosts multiple physical media types, usually including ...
