摘要： 基于对象存储的核心是将存储空间管理从存储应用中分离，其中元数据服务器(MDS)负责逻辑视图管理和提供全局命名空间。该文针对MDS的引路导航性能，提出一种主从备三重链式结构，在不增加硬件成本的前提下，能提供无间断的MDS服务，确保了系统的高可靠性。

Abstract: The most immediate effect of object-based storage is the offloading of space management from storage applications. MetaData Server (MDS) is responsible for the logical view management and provides unique naming space. To play an important role of navigation for MDS, this paper proposes a method of master/slave/standby chain backup. It can provide a continuous serving and ensure high reliability of MDS without adding any hardware device.
