Design And Implementation Of Virtual File And Management System For Blue-ray Optical Disc Library

In recent years,with the high-speed development of information technology,the demands of data storage level have been rising sharply in all professions and trades,especially the amount of archived data has been growing rapidly.With the characteristics of large capacity and low cost,Blue-ray optical disc library quickly became a popular storage media to archive data.But there are still some problems like drives reading files slowly and being unable to manage files effectively.These problems seriously hampered the development of Blue-ray optical disc library.This industry is in urgent need of a virtual file system based on enterprise Blue-ray optical disc library to help disc library business improve this situation.This paper designed and implemented the virtual file and management system for enterprise Blue-ray optical disc library successfully.This system developed by Visual Studio 2012,adopted C/S and B/S frameworks as platform to develop,SQL Server 2012 as the database management system.This system developed a set of virtual disc file management system running in windows system platform used by Dokan framework,to implement these operations like reading,uploading,modifying and deleting files using windows resource manager,and improving the user's experience degrees.At the same time,the asynchronous cache mechanism had joined this system,the cache space developed by high-speed disk will be wrote into the middle of the disc to make user's file operations more transparent,thus improve the efficiency of user's operations greatly.In addition,this system aimed at the requirements of user storing data safely divided functional module operations into two platforms to manage by analyzing user's rights.The basic operations of the file will be put into the virtual disc clients and the management operations of the system will be adopted into browser controller to manage.So the security of information can be ensured from the entire system.This system had put the enterprise Blue-ray optical disc library package of products into use after the completion of development and test.Now it has been widely used in the market with a good corporate feedback.This system greatly enhanced the user's experience by managing files effectively and developing high-speed cache,not only resolved the bottleneck of Blue-ray Disc storage,but also enhanced the overall competitiveness of the Blue-ray optical disc library in huge data archiving storage devices.
