一种动态连接存储资源和计算资源装置的设计与实现

The Design and Implementation of Device which Dynamically Connects Storage and Computation

存储与计算的分离,重新定义了计算机的使用模式。计算资源和存储资源的动态重构,不仅提高了资源的利用率,而且简化了管理。一种实现这种新模式同时又兼容于传统机制的方案是在存储设备级截获数据流,并转接到网络,利用现在网络高带宽、可靠和灵活的特性提供高速、稳定和动态的服务。本文将介绍动态网络硬盘nHD(network HardDisk)的设计和实现,给出并分析其运行性能。

The separation of storage and computation redefines the using model of computers. And the ability of reconnecting computation resources and storage resources not only improves the utilization of resources, but also simplifies the management. In this sense, we develop a method to implement this new model compatible with the traditional mechanism, which intercepts data stream onto networkat the storage device level, thereby taking advantage of highbandwidth, reliability and flexibility of networking to provide high-speed, stable and dynamic accessing services. In this paper, we give a detailed introduction of the designand implementation of the dynamic network hard disks nHD, and present the actual testing and relative analysis.
