A Study On The Transformation Performance Improvement Of Cloud Storage System

Cloud storage system is a derivative concept of the cloud computing system,and it is a kind of cluster system including large amounts of the distributed storage resources,which provide safe and reliable network storage service.When configured with a large number of storage resources and ignoring its collaborative computing function,the cloud computing system will evolve into the cloud storage system.Cloud storage system is a new manner of the data storage,and the service it provides to the end user is reliable in storage,convenient in use,and low in cost.When using the cloud storage system to store the information,the users can access the data at any time by the device which has the function to connect the Internet.At present,although the cloud storage systems can provide users with better data storage performance comparing with the local storage method,they are facing such performance problems as the low transmission rate,large transmission duration and transmission instability.As the increasing of the amount of data storage in the cloud storage system,the transmission performance problem will become more evident,and ultimately it will affect the user's choice of the way to store data.Therefore,further improvement of cloud storage system architecture and research to focus on increasing the performance of data transmission,are of great significance to promote the development of cloud storage business.This paper mainly focuses on the study of data transmission process,putting forward an hybrid storage architecture of the static nodes and dynamic nodes,and designing a new work mechanism based on vandermonde data coding.These two system improvement measures will be able to improve the data transmission performance of the cloud storage system significantly.The work of this paper is organized as follows:1.Giving a detailed introduction and analysis of the cloud storage system's basic architecture and work mechanism.2.Putting forward an new hybrid storage structure of the cloud storage system including static data nodes and dynamic data nodes.3.Designing two new work mechanisms of the hybrid storage structure basing on vandermonde data coding.4.Verifying the effectiveness of the two proposed schemes to improve the transmission performance of cloud storage system.
