This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).With recent advances in capacity, bandwidth, and durability, NAND flash memory has been successfully employed in mobile devices like PDAs and laptops and it is starting to replace hard disks in desktop systems. Integrating NAND flash memory into server domain applications, which normally demands a high level of data reliability and exceptional random I/O performance, however, is much more challenging because NAND flash memory exhibits relatively poor random write performance and insufficient reliability due to limited erasure cycles. To address these problems, an architectural support for flash SSD must be devised in order to fundamentally boost its performance and longevity by a software/hardware combined effort. In this project, we will develop a novel flash disk storage architecture that exploits the addition of RAM and dedicated software schemes to incorporate flash SSDs into enterprise-class storage systems. We plan to implement a flash disk array prototype and deploy it in real-world data-intensive application. In addition, we will develop new software techniques such as a double-buffer write ordering management scheme and an inter-disk wear-leveling technique. This project will contribute to energy conservation, performance enhancement, data management, and reliability technology for enterprise-class storage systems by developing the flash disk array storage architecture, accompanied by an array of new software schemes. This project will also promote teaching, learning, an training by exposing both undergraduate and underrepresented students to technological and scientific underpinnings in the field of server-class storage systems.

该奖项是根据2009年的《美国回收与再投资法》（公法111-5）资助的。随着产能，带宽和耐用性的最新进展，NAND闪存已成功地用于PDA和PDAS和笔记本电脑等移动设备，并且它开始在台式机系统中替换硬盘。但是，将NAND闪存整合到服务器域应用程序中，这些应用程序通常需要高水平的数据可靠性和出色的随机I/O性能，但是由于NAND闪存表现出相对较差的随机写作性能和由于擦除周期有限而导致的可靠性不足。为了解决这些问题，必须设计对Flash SSD的体系结构支持，以从根本上通过软件/硬件组合的工作来提高其性能和寿命。在此项目中，我们将开发一种新颖的Flash磁盘存储体系结构，该架构利用RAM和专用软件方案的添加，将Flash SSD纳入企业级存储系统中。我们计划实现闪存磁盘阵列原型，并将其部署在现实世界中数据密集型应用程序中。此外，我们还将开发新的软件技术，例如双缓冲器写入订购管理方案和盘间磨损水平技术。该项目将通过开发Flash Disk Array存储架构，并伴随着一系列新的软件方案，从而有助于企业级存储系统的节能，性能增强，数据管理和可靠性技术。该项目还将通过使本科生和代表性不足的学生培养教学，学习和培训，以了解服务器级存储系统领域的技术和科学基础。
