The Design And Implement Of Cloud Storage Scheme Combined With OpenStack And Ceph

With the increasing demand for information storage,the demand for storage is more and more high,the traditional storage method can not meet these needs.It is well known that most of the traditional storage methods can only rely on single nodes to store information,not only high cost and low efficiency,but if the physical disk of single node is damaged,the data will be lost and can not be retrieved.Set some enterprise users to grow and grow,the information reserves are much more than the current capacity,the efficiency of artificial expansion is also extremely low,and the use of hard disk is very low;there may be some disks already full,some disks are still empty,if the enterprise wants to transfer the data to other places is also very difficult,it is necessary to spend a lot of manpower and material resources to complete the data transfer.Shift work.What kind of ways should be used to store data and manage them conveniently is the urgent need for the current enterprises.The intern's smart technology Software Co.,Ltd.(Nanjing smart tech software Co.,Ltd.is the first OpenStack desktop cloud manufacturer in the industry to provide firm and reliable and reliable cloud computing services,with the features of extremely simplified operation and maintenance,multidimensional security protection,easy expansion,easy deployment and so on)also face the same problems.By analyzing the current research status at home and abroad and combining the needs of the company,this paper studies and implements the four aspects of the design of the cloud storage system,the design of the system bottom,the design and implementation of the system function interface,the deployment and debugging of the system.The main work of this paper is as follows:First,it analyzes the related technologies such as cloud computing and OpenStack,compares the advantages and disadvantages of Ceph and Swift,puts forward two schemes combining Ceph and OpenStack,gives the design framework of the scheme,compares two schemes,analyzes the feasibility and complexity of the scheme,and determines the final scheme.Then,it is the design and deployment of the bottom of the cloud storage system.The underlying design includes the use of the server,the selection of the network nodes,the Monitor node and the arrangement of the OSD nodes;the bottom deployment uses three servers to build the cluster of Ceph,and needs to set up two networks for the cluster,including the public network and the cluster network,so that the cluster can run healthily;Secondly,the interface is designed according to the needs of the user,the logic of the interface is analyzed,and the function of the interface is realized on the basis of the Ceph cluster.The interface is developed two times in the Horizon.The system can realize the functions of data storage,downloading and so on.Not only can we provide the storage and storage service of the object,but also can dynamically and effectively expand the data when the data is too much,so that the data storage can be stored.More efficient and more convenient.Finally,the system is deployed to the company's server to verify whether a simple object storage function can be provided,and the reliability of the system is verified,and the system is highly reliable.
