    Abstract: Scheduling operations such as asynchronous file system operations in a network storage system is accomplished by applying a bid-price online auction methodology, in which bid (willingness-to-pay) values and price (cost) values are dynamically set by storage clients and a storage server, respectively, based on utilization of computing resources. The system provides a framework for adaptively scheduling asynchronous file system operations, managing multiple key resources of the distributed file system, including network bandwidth, server I/O, server CPU, and client and server memory utilization. The system can accelerate, defer, or cancel asynchronous requests to improve application-perceived performance. Congestion pricing via online auctions can be employed to coordinate the use of system resources by clients, so clients can detect shortages and adapt their resource usage.

    Abstract translation: 在网络存储系统中的异步文件系统操作的调度操作是通过应用投标价格在线拍卖方法来实现的,其中存储客户端动态地设置出价(付费意愿)价值和价格(成本)值,并且 存储服务器,分别基于计算资源的利用。 该系统为自适应调度异步文件系统操作,管理分布式文件系统的多个关键资源,包括网络带宽,服务器I / O,服务器CPU以及客户端和服务器内存利用率提供了框架。 系统可以加速,推迟或取消异步请求,以提高应用感知性能。 通过在线拍卖的拥堵定价可以用来协调客户对系统资源的使用,客户可以发现短缺并调整其资源使用情况。
