Multiview Storage Systems

本项目旨在构建一个多视图存储系统MVSS。 与多视图数据库系统类似，MVSS允许在物理磁盘上动态生成同一文件的多个视图。为了支持多个视图，设备将被“多端口”。 可以定制文件的不同视图，以在多端口设备上提供不同类型的服务。 MVSS将服务部署与文件系统实施分开，从而允许在存储系统的各个级别执行服务。MVSS通过文件系统命名空间向用户提供文件的多个视图。通过这些视图，MVSS提供了一种灵活且可扩展的方式来支持包括设备级增强功能在内的广泛服务。在本项目中，我们将构建一个实验测试床，并计划通过真实的应用程序对其进行评估。数据库选择操作、QoS的MPEG过滤、排序和许多其他应用程序将用于驱动原型系统。

This project proposes to build a Multi-View Storage System, MVSS. Similar to a Multi-View Database System, MVSS allows multiple views of the same file on the physical disk to be generated dynamically.To support multiple views, devices will be "multiported". Different views of a file can be customized to provide different types of service at a multiported device. MVSS separates the deployment of services from file system implementations and thus allows services to be performed at various levels of thestorage system. Multiple views of the file are provided to the user through file system namespace.Through these views, MVSS provides a flexible and extensible way for supporting a wide range of services including device-level enhancements.In this project, we will build an experimental testbed incorporating these ideas and plan to evaluate them through real applications. Database Select operations, MPEG filtering for QOS, sorting and anumber of other applications will be used to drive the prototype system.
