A Solution Of Private Cloud Storage

With the continuous development of computer technology,many new technologies are appeared. Currently,cloud computing technology was seen the third wave of IT following the personal computer technology and Internet technology.The domestic and foreign enterprises and researchers are actively involved in the cloud computing industry, the governments also increased the support of cloud computing industry.Cloud computing is the development of distributed processing,parallel processing and grid computing, or we can say it is the commercial implementation of these concept.Cloud storage is a derivative and development of cloud computing.In simple terms, cloud storage is a cloud computing system that for data storage and management.In this paper,to the question that the current cloud storage especially the private cloud storage has a high technology threshold, complicated application configuration and expensive solution cost.Presents a private cloud storage solutions that has a large storage capacity, high data reliability, low application costs, and achieve cross-platform, data encryption and disaster recovery, network and storage load balancing.The main work is as follows:1.The design of cloud shared distributed storage.Proposed a chain structure based on NFS dual role,through NFS client role and NFS service role,establish a shared storage access chain at the server,to build a high degree of coupling, scalable, high-efficiency storage device collection chain.Realization of dynamic, cheap, simple scalable storage.2.Design a consistent external access interface that based on distributed storage design.Including the integration of interface design,master-slave architecture design,consistent communication protocols,tasks distributor(SmartDNS) design,operator recroder(Database) design,and gives the protocol content and interactive process of the interface.3.The design of network and storage load balancing.This paper proposes a QoS-based load balancing algorithm that taking into account the network load balancing and storage load balancing,it schedule the storage server by calculate the priority of candiate server through a Priority function.4.In consideration of the safety status of private cloud industry,this system adds a data encryption module,it applied3DES encrypted the data packets when transfered the file that required a higher security.To achieve the disaster recovery,this system applied same city backup and remote mirroring because of they has higher efficiency and lower investment.At the end of the paper according to the design thought and method, has realized the cross-platform application.This project successfully applied in enterprise and institute data disaster backup, the application results achieved the design anticipated performance and indicators.
