【摘要】 文章研究了客户机/元数据服务器/存储服务器三层结构网络文件系统中,针对改善元数据服务效率的优化策略,包括客户节点接口中的路径解析加速、元数据服务器上的元数据存取优化及元数据服务器组的结构支持等几部分,作者通过建立分析模型与实际系统模拟的方法,证明这些策略的确可改善系统性能,优化系统效率。更多还原

【Abstract】 I n network file systems with client/meta-data severs/storage severs architect ure,it is importance to improve the performance of meta-data operations.We h ave studied the optimizing strategies to improve the performance of meta-data o perations,which include a strategy of meta-data layout structure adjusting an d an improved the pathname lookup algorithm.In this paper,we also put up wi th an analytical model and a simulate model to analyse these optimizing strategi es.The result showed that these optimizing strategies is effe ctive.更多还原
