基于决策调度的Cache集群存储架构

阐述了一个应用于网络存储的新集群架构,该架构的构建是将网络Cache技术与集群技术结合,其核心是节点服务器的缓存机制以及后台的集群决策.架构均衡了系统的负载,并充分利用资源,向用户提供稳定、快速的存储服务.架构节点使用普通PC计算机作为服务器,对于企业级的存储应用能达到最优性价比.讨论了集群架构、集群后台决策机制以及Cache调度算法.

A New Network Storage Architecture of Cache-Cluster Based on Scheduling Decision Strategy

In this paper, a novel cluster architecture integrating with network cache and cluster techniques was proposed for network storage. The architecture of the cluster, the cache scheduling algorithm in node severs and the background decision strategy were introduced in detail. The results showed that our cluster architecture could effectively alleviate the load of the system, and provide stable and convenient storage service to customers. Furthermore, with excellent performances and relatively low prices owing to the use of the common personal computers as node sever, the cluster architecture is very suitable for the enterprise- level applications.
