This project proposed to build an experimental system that can provide scalable request-specific file service. The demands on the file and web servers continue to increase along with the increase in the diversity of application requirements (deterministic guarantees for continuous media retrieval, short latencies for interactive applications and throughput requirements of regular file retrieval). The new applications' (multimedia and database decision support) requirements of large amounts of I/O bandwidth also prompt new directions in providing file service. These application trends, coupled with the trends in the availability of hardware such as network-attached disks, and cheaper processing power, prompt us to investigate the following: (a) How to provide flexible service in a file/storage system?(b) How to provide scheduling and resource allocation support for integrated service of multiple types of requests?(c) How to provide support for migrating service close to the data?(d) What kind of application interface should be provided for flexible service?This project proposed to build and experimental prototype based on a cluster of PCs. The prototype will be instrumental in evaluating the validity and efficacy of the proposed file-specific request service.

本计画提出建立一个实验性的系统，以提供可扩充的特定请求档案服务。对文件和Web服务器的需求随着应用需求多样性的增加而沿着增加（连续媒体检索的确定性保证、交互式应用的短延迟以及常规文件检索的吞吐量需求）。 新的应用（多媒体和数据库决策支持）对大量I/O带宽的需求也促使了文件服务的新方向。 这些应用程序的趋势，再加上硬件的可用性，如网络连接的磁盘，和更便宜的处理能力的趋势，促使我们调查以下内容：（a）如何提供灵活的服务，在文件/存储系统？(b)如何为多种类型请求的集成服务提供调度和资源分配支持？(c)如何为迁移服务提供贴近数据的支持？(d)灵活服务应该提供什么样的应用接口？本项目提出了建立和实验原型的基础上集群的PC机。 该原型将有助于评估建议的文件特定的请求服务的有效性和效率。
