借鉴了云存储的的基本思想与技术平台，针对大容量数据的海量和访问频度不同的特点，提出多层块区概念，并研究基于此的数据存储方法。对数据访问性能的定量分析表明，合理划分块区能够得到比传统存储方法更好的访问效率。最后阐述了块区设置的思路和方法。研究结果可为存储系统的设计提供参考。%Based on the ideology and technical platform of cloud -storage, aiming at the characteristics of mass data which are quite large and are accessed with different frequency,the concept of multi -level block is brought up and the storage method is put forward as well.The quantitative analysis for access performance of the data shows that dividing blocks reasonably can get better access efficiency than classic method does.Some principles are demonstrated over block setup and the conclusions can provide reference for the design of storage system.
