Even though page cache layer of operating system enhances the performance of mobile devices by reducing the number of write requests issued to the underlying mobile storage, the mobile devices still suffer from the excessive write requests. This is because mobile applications frequently trigger synchronous writes with fsync() system call to guarantee the reliability of each application. Unfortunately,...
This paper proposes a novel buffering algorithm for write buffer, comprised of DRAM and NVM, in NAND flash storages of the home cloud server is proposed. As adopting dirty first migration and clean page caching technique, the algorithm may improve performances and lifetime of storage system of the home cloud server. The experimental results show that the algorithm improved buffer hit ratio by up to...
The I/O caused by background applications shorten the lifespan of mobile devices because they affect the behavior of power intensive hardware. Our efficient power management scheme addresses this problem by killing unnecessary applications. Our results show LPK extends the lifespan up to 9.4% compared to baseline on a real device.
Recently, eMMC is widely being used in mobile devices because of its characteristics such as low cost, small size, and low power consumption. In this paper, we analyze features of eMMC based on commands such as Trim, Discard, and Background to investigate how do commands affect the random write performance and lifetime of the NAND flash memory. Also, we propose a method that uses the Background command...
NAND flash storage devices are now revolutionizing storage stacks. As their capacities are rapidly increasing, they are now being adopted virtually in all classes of computing devices, including mobile devices, desktop computers, and cloud servers. However, there are two remaining problems: first, as flash density increases, the lifetime of the storage medium decreases rapidly. Second, random writes...
