DiskSim Project Introduction

DiskSim is a disk system simulator originally developed at Carnegie Mellon University to support storage research. It models disk performance accurately and can be used in a variety of design environments. The document discusses extensions to DiskSim that model solid state drives (SSDs), hard disk drives (HDDs), and phase change memory (PCM). It notes that an SSD extension provides limited simulation of an idealized SSD, while Dempsey extends DiskSim to model HDD power consumption and performance characteristics. It states that current project progress involves developing power consumption models for the SSD extension, integrating and improving Dempsey for HDDs, and developing an independent PCM extension including power measurement.
