Abstract
Recently, computer processing speed has been accelerating because of the advanced computer hardware technology. As the speed of computing increases, the amount of data to be processed increases. On the other hand, the I/O bottlenecks occur where the hard disk processing speed is slow. To alleviate these bottlenecks, the SSD cache method, which is faster than the hard disk and uses the SSD device that is cheaper than a RAM, was used to solve the problem. However, in the server environment, the SSD cache which is smaller in capacity than the hard disk, was quickly filled with various write patterns and continuous write processing of multiple processes. In this paper, we propose an adaptive SSD cache method that identifies and writes variable write patterns to delay the SSD cache full phenomenon where the SSD cache is rapidly filled and write performance sharply decreases.
