激光全息数字图像补偿资源云存储平台设计

Design of cloud storage platform for digital image compensation resource based on laser holography

针对传统激光全息数字图像补偿资源存储系统容量小、安全性差、冗余度高、数据交互能力弱的不足,提出一种基于Hadoop架构的资源云存储平台设计。云存储平台的核心由综合管理、并行存储和查询备份三大模块构成,分析了各模块的功能和云存储平台的网络拓扑结构;最后分别介绍了平台的HDFS体系结构和MAP/REDUCE运算模型。仿真实验表明,提出的激光全息数字图像补偿资源云存储平台设计,具有更大的存储容量和数据交互能力,在数据存取过程中耗时更短,同时数据查询效率表现方面也具有较大优势。

Aiming at the shortcomings of traditional laser holographic digital image compensation resources storage system with small capacity, poor security, high redundancy and weak data exchange capabilities, this platiform design based on architecture is proposed. The core of cloud storage platform consists of comprehensive management module, parallel storage module and query and backup module. It respectively analyzed the functions of main modules, network topology. Finally introduced the system structure and operation model. Simulation results show that the higher storage capacity and ability of data interaction design of holographic digital image resources compensation cloud storage platform is proposed. The shorter time and safety performance in the data access process are also advantages.
