Research on the Establishment of Distributed Storage Virtual Geographic Environment Based on Lustre File System

Nowadays the geographic spatial data in surveying and mapping field are increased explosively. Meanwhile, the users need more and more security and stability in data storage, traditional way of data storage cannot fulfill the requirement of users. By summing up the structure and the trait of Lustre file system, we use Luster file system to store massive geographic data, the main framework of Distributed Storage Virtual Geographic Environment System is given, we establish meta data server, data storage server, and Linux client, explain the process of obtaining spatial information in storage system. Finally, an experiment is finished to prove the high-effect and high-stability of distributed storage virtual geographic environment by using Lustre.
