RUI/ROA: Support Tools for Memory-Based Filesystem

点击翻译按钮获取中文摘要

Abstract:The Conquest hybrid disk/memory file system takes a new approach tofilesystem design by storing most information in RAM, devoting diskonly to large files. Preliminary results have shown great benefitsfrom the Conquest approach, despite the fact that the on-disk portionof the file system has yet not been optimized. In this research, wewill investigate the optimal method of storing those large disk-basedfiles. After reviewing prior research in disk layout, we will designand implement a layout that is optimized for storing large files in anenvironment that is free of metadata and small files. We will alsodevelop a "cleaner" that will dynamically adjust the arrangement ofon-disk data to optimize the performance of disk access. Finally, wewill take measurements to quantify the improvements brought by the newapproach.
