Abstract
The present invention is directed to a method for providing storage acceleration in a data storage system. In the data storage system described herein, multiple independent controllers may be utilized, such that a first storage controller may be connected to a first storage tier (ex.—a fast tier) which includes a solid-state drive, while a second storage controller may be connected to a second storage tier (ex.—a slower tier) which includes a hard disk drive. The accelerator functionality may be split between the host of the system and the first storage controller of the system (ex.—some of the accelerator functionality may be offloaded to the first storage controller) for promoting improved storage acceleration performance within the system.
