两级存储虚拟化模型

摘要

通过分析比较带内和带外存储虚拟化的优缺点,提出融合两种方式的新的存储虚拟化模型.该模型分别在块级和文件系统级两层都实现存储虚拟化.%By analyzing and comparing the pros and cons between in-band and out-of-band storage virtualization models, a novel storage virtualization model which fuses the two patterns together is proposed. The proposed model realizes storage virtualization at both the block level and the file system level.
