One of the most recent changes is how auto-tiering uses storage to take advantage of flash speed boosts. "Rather than using spinning disk drives as the latest greatest drive technology, which are mechanical and cause heat and vibration, we use the latest class of solid-state drives," says Bob Fine, director of storage product management at Dell. "The new technology leverages solid state drives -- data coming in that's performance oriented, we place on solid state."
The innovation: The auto-tiering uses only a small amount of flash for the high-performance apps. Dell auto-tiering can also distinguish between higher cost single-level cell flash and slower, higher capacity multiple-level cell. These kinds of smart adjustments occur automatically and reduce the cost of using flash.
