摘要
对云存储系统环境中的数据布局策略进行了论述与总结。首先讨论了云存储技术的起源以及云存储系统不同于传统集中式存储方法和现有网络存储技术的独特特征,然后讨论了面向云存储系统的数据文件布局策略;考虑到云存储系统对于系统可靠性、可用性以及可扩展性等性能指标具有更高要求,接下来对面向云存储系统的数据副本布局策略进行了论述。数据布局策略对于云存储系统的性能指标具有重要决定作用,全文工作将为未来研究高能效的商用云存储系统奠定基础。
The paper discusses and summarizes the data layout strategies in cloud storage system environment,introducing the origin of the cloud storage technology and its unique characteristics which differed greatly from the traditional centralized storage method and the current network storage technology,as well as the data file layout strategies in cloud storage system. It also expounds the data replica layout strategy in cloud storage system,in view of higher requirements in the cloud storage system for system reliability,availability and scalability performance. It is obvious that the data layout strategy plays an importance role in the performance of cloud storage system,so the work of this paper will be a guideline of our future study on the highly energy- efficient,commercial cloud storage system.
