While continued improvements in processing speeds and disk densities improve computing over time, the most fundamental advances come from changing the ways in which components interact. Delegating responsibility for some operations from the host processor to intelligent peripherals can improve application performance. Traditional storage technology is based on simple fixed-size accesses with little assistance from disk drives, but an emerging standard for object-based storage devices (OSDs) is being adopted. These devices will offer improvements in performance, scalability and management, and are expected to be available as commodity items soon.The PIs will examine multiple aspects of the mismatch between the needs of a parallel file system, in particular PVFS2, and the capabilities of OSD. Topic areas include mapping data to objects, metadata, transport, caching and reliability. The PIs will examine the feasibility of OSDs for use in parallel file systems, discovering techniques to accommodate this high performance usage model, and suggest extensions to the current OSD standard as needed.

虽然随着时间的推移，处理速度和磁盘密度的不断提高提高了计算能力，但最根本的进步来自于改变组件交互的方式。将某些操作的责任从主机处理器委托给智能外设可以提高应用程序的性能。传统的存储技术基于简单的固定大小访问，几乎没有磁盘驱动器的帮助，但正在采用一种新兴的基于对象的存储设备（OSD）标准。这些设备将在性能、可扩展性和管理方面提供改进，预计很快将作为商品上市。PI将检查并行文件系统（特别是PVFS 2）的需求与OSD功能之间不匹配的多个方面。主题领域包括将数据映射到对象、元数据、传输、缓存和可靠性。PI将检查OSD用于并行文件系统的可行性，发现适应这种高性能使用模型的技术，并根据需要建议对当前OSD标准的扩展。
