摘　　要：非对称集群存储系统以其在高I/O性能、高可扩展和易管理等方面的优势而成为研究的热点.存储虚拟化是提高其可扩展性和易管理性的关键技术之一.从构建智能存储路由器的思路出发,提出了一种分层映射的块虚拟化方法,可实现资源的集中式管理和分布式映射.该方法支持物理存储资源的动态添加,从而可使整个存储系统具有良好的可扩展性和可管理性.Asymmetric cluster storage systems are becoming a focus due to the high I/O performance,high scalability,easy management,etc.Storage virtualization is one of the key technologies to improve the scalability and manageability of cluster storage systems.From the perspective of building an intelligent storage router,this paper presented a block virtualization method with layered mapping,by which central management and distributed mapping for resource were implemented.This approach supports physical storage resources to be joined in storage system dynamically,and enables good scalability and manageability for the whole storage system.
