摘要
随着存储数据的爆炸式增长,存储空间的迫切需求,虚拟存储技术已经广泛应用到存储系统中。根据操作系统中内存管理的虚拟内存机制,将其扩展引入到整个存储系统的管理中,并与传统的存储虚拟化技术相结合,提出了双层次存储虚拟化的结构,实现了逻辑层和虚拟层的双层虚拟,以屏蔽存储设备的异构性,极大提升存储资源利用率。
With the explosive increase of storage data and the urgent need for storage space, the storage virtualization technology is widely used in the storage system. The text offers a storage virtualization architecture of double layer, combining the traditional storage virtualization technology with the virtual memory mechanism which has been applied in the memory management of operating system and will be expanded and led to the whole storage system. The architecture realizes the virtualization in the logical and the virtual level, shields the isomerism of the storage equipments and extremely improves the utilization ratio of the storage resources.
