Weak Center Based Decentralized Shared Private Cloud Storage System

With the development of IT technology,data storage media and storage mode,through the perforated tape,floppy disk,hard disk,CD,disk array,large-scale network disk array stage.With the rise of the concept of cloud computing,cloud storage has also become a new storage model.As a basic service,storage can be obtained on demand through the network.This new use of the model,more close to the needs of users,with advanced nature.There are a lot of cloud storage vendors,to enterprises,people to provide a system storage services.But the user's storage needs are different,the function is also different,so people explore a lot of different cloud storage application scenarios,patterns,technology.For a large number of mutual trust set of network nodes,but a stable speed is limited between network nodes connected to the hypothesis,we propose a low center of equations based storage architecture.The architecture pro vides all nodes as a whole,providing decentralized data storage services for each node in the system.Each node is a storage provider in a private cloud system and a user of a private cloud storage service.One or a limited number of weak functions of the central node for the entire system to provide limited control and task allocation.The main calculation and storage functions are negotiated by each node.O f course,allowing a small number of nodes in the system to store only the user,or a small number of nodes is only a storage service provider.The innovation of this system is to propose a decentralized decentralized storage service model.In addition to the center,each node has the same function,and can provide storage service.It is also a service provider and a service provider.The system is a simple and easy to build a private cloud storage system,you can reduce the use of the threshold,so that more units,the park from the cloud to benefit from storage.In this paper,we propose a shared private cloud storage model for a large number of trusted and network-constrained scenarios.Model for file storage,file storage process,the process flow system is designed in detail.Using the relevant mature open source technology and framework,the cloud storage system for a specific realization.
