I/O路径模型（IOPm）是并行文件系统体系结构和部署它们的机器的图形表示。借助IOPm，可以快速分析和区分文件系统和机器配置。与机器和文件系统体系结构的典型表示相反，该模型将客户端访问的数据或元数据路径可视化。包括硬件组件（如客户端和服务器节点）的抽象功能，以及软件方面（如高级I/O库、集合I/O和缓存）。冗余也可以表示出来。除了用于分析的标准化表示的优势之外，IOPm还通过突出显示与性能相关的功能，帮助识别和沟通机器和文件系统配置中的瓶颈。通过从承载它们的组件中抽象功能，IOPm将能够构建接口来监视文件系统活动。
The I/O path model (IOPm) is a graphical representation of the architecture of parallel file systems and the machine they are deployed on. With help of IOPm, file system and machine configurations can be quickly analyzed and distinguished from each other. Contrary to typical representations of the machine and file system architecture, the model visualizes the data or meta data path of client access. Abstract functionality of hardware components such as client and server nodes is covered as well as software aspects such as high-level I/O libraries, collective I/O and caches. Redundancy could be represented, too. Besides the advantage of a standardized representation for analysis IOPm assists to identify and communicate bottlenecks in the machine and file system configuration by highlighting performance relevant functionalities. By abstracting functionalities from the components they are hosted on, IOPm will enable to build interfaces to monitor file system activity.
