This paper focuses on evaluation of the effectiveness of optimization at various layers of the IO path, such as the file system, the device driver scheduler, and the disk drive i...
We propose a new approach for I/O scheduling that performs on-line simulation of the underlying disk. When simulation is integrated within a system, three key challenges must be a...
