Abstract
Acceleration of I/O access to data stored on large storage systems is achieved through multiple tiers of data storage. An array of first storage devices with relatively slow data access rates, such as hard disk drives, is provided along with a smaller number of second storage devices having relatively fast data access rates, such as solid state disks. Data is moved from the first storage devices to the second storage devices to improve data access time based on applications accessing the data and data access patterns.
