42 Rethinking the File System Design on Flash-based Storage

چکیده
Flash memory is gaining great popularity in both embedded and enterprise systems. Compared to legacy hard drives, flash devices get rid of mechanical components and significantly improve performance. However, flash memory is not merely a faster storage media, and its characteristics provide opportunities of new storage system designs. In this paper, we summarize disruptive techniques on flash storage respectively in areas of storage architecture, system software and distributed protocols. With a focus on file system designs for flash storage, we describe our work from three aspects: the hardware support, the storage management and the namespace management. With preliminary research in this area, we believe that it needs disruptive techniques in I/O stack to exploit the potentials of flash memory.

Extending the lifetime of flash-based storage through reducing write amplification from file systems
Flash memory has gained in popularity as storage devices for both enterprise and embedded systems because of its high performance, low energy and reduced cost. The endurance problem of flash memory, however, is still a challenge and is getting worse as storage density increases with the adoption of multi-level cells (MLC). Prior work has addressed wear leveling and data reduction, but there is ...
متن کاملF2FS: A New File System for Flash Storage
F2FS is a Linux file system designed to perform well on modern flash storage devices. The file system builds on append-only logging and its key design decisions were made with the characteristics of flash storage in mind. This paper describes the main design ideas, data structures, algorithms and the resulting performance of F2FS. Experimental results highlight the desirable performance of F2FS...
متن کاملA Flash File System to Support Fast Mounting for NAND Flash Memory Based Embedded Systems
In embedded systems, NAND flash memory is typically used as a storage medium because of its non-volatility, fast access time and solid-state shock resistance. However, it suffers from out-place-update, limited erase cycles and page based read/write operations. Flash file systems such as JFFS2 and YAFFS, allocate memory spaces using LFS (Log-structured File System) to solve these problems. Becau...
متن کاملDesign of Embedded Database Based on Hybrid Storage of PRAM and NAND Flash Memory
Andorid which is the popular smart phone OS uses a database system to manage its private data storage. Although the database system supports a powerful and lighteweight database engine, its performance is limited by a single storage media, NAND flash memory, and a single file system, YAFFS2. In this paper, we propose a new embedded database system based on hybrid storage of PRAM and NAND flash ...
متن کاملAn Efficient Metadata Index Structure for Flash File Systems
SUMMARY One way to use NAND flash memory as storage media is a flash file system. In order to design a high-performance flash file system , designing an efficient index structure that constitutes the locations of metadata including directories and files in flash memory is important. For large-capacity storage, the index structure must be stored in the flash memory to achieve low memory consumpt...
