Abstract

We propose a new method for tiered storage and evaluate the characteristics of the method. In this method, a fast tier is divided into two areas, and the data in each area is managed on the basis of two input/output (I/O) measurement periods. When I/Os to these areas increase, the proposed method allocates frequently accessed areas to a higher tier in advance, therefore, improving the total system I/O performance. When frequently accessed areas rarely move, the proposed method is the most effective and improves the total system I/O performance by up to 30.4%.
