Mobile computing is sweeping the world. Recent studies are pointing to the permanent storage in mobile computing platforms being a weak link. Due to considerations of power and physical footprint, flash has been the storage technology of choice hitherto in mobile platforms. Flash and other newer storage technologies, such as PCM and STT-RAM, have their own idiosyncrasies both from the point of view of architecting them and integrating them in the operating system. In this project, we focus on the system software and hardware issues, in an integrated fashion, in the construction of high-performance storage architecture for mobile platforms. We will analyze the source of storage-related performance bottlenecks on mobile platforms at different levels of the software stack using a combination of measurement, simulation, and real implementation on existing and emerging mobile platforms. We will propose solutions both at the system software and architecture levels for advancing the state-of-the-art in storage for mobile platforms, and conduct detailed quantitative evaluation of our solutions. This project with its focus on advancing the state-of-the-art in mobile storage technology can have unexpected economic and societal impact. We intend to make the research artifacts from this project (traces, workloads, and software) available to the broader research community through open source efforts. Despite technological advances, system software has lagged significantly behind the hardware in delivering the expected performance. The vision behind this project is an attempt to bridge this gap for the storage side of the system software stack through an integrated hardware/software approach.

移动的计算正在席卷全球。 最近的研究指出，移动的计算平台中的永久存储是一个薄弱环节。出于对功率和物理占用空间的考虑，闪存一直是迄今为止在移动的平台中选择的存储技术。闪存和其他较新的存储技术，如PCM和STT-RAM，从架构和集成到操作系统的角度来看，都有自己的特性。 在本项目中，我们将重点放在系统的软件和硬件问题，在一个集成的方式，在移动的平台上的高性能存储架构的建设。 我们将结合现有和新兴移动的平台上的测量、模拟和真实的实施，分析不同软件堆栈级别的移动的平台上与存储相关的性能瓶颈的来源。我们将在系统软件和架构层面提出解决方案，以推进移动的平台存储的最新发展，并对我们的解决方案进行详细的定量评估。 该项目专注于推进移动的存储技术的发展，可能会产生意想不到的经济和社会影响。 我们打算通过开源努力将该项目的研究工件（跟踪，工作负载和软件）提供给更广泛的研究社区。 尽管技术进步，但系统软件在提供预期性能方面远远落后于硬件。该项目背后的愿景是尝试通过集成的硬件/软件方法来弥合系统软件堆栈存储方面的这一差距。
