【摘要】 提出了一种基于对象的存储系统管理框架,它使用统一的对象接口来访问flash或者磁盘。重点对基于对象模型的闪存文件系统进行了研究设计,在系统中引入了段的层次来进行对象管理,通过分析能够显著减少徘徊树问题引起的大量数据更新次数,并避免了垃圾回收时多余的I/O操作,缓解了垃圾回收过程中的数据锁定问题。更多还原

【Abstract】 This paper presented a management framework of object-based storage system,which used the uniform object interface to access flash and disk.It designed object-based flash file system(OFFS) to manage the flash storage.In OFFS,introduced a segment level to store the object.The discuss shows it can reduce the update time caused by wonder tree,easy to implement and can work without serious locking problems during garbage collection.更多还原
