Design And Implementation Of Distributed Storage In Data Center Based On Ceph

With the fast development of cloud computing,big data and mobile Internet technology,the amount of data grows so rapidly that curent study mainly focuses on the storage of mass data.The traditional centralized storage methods can not meet the current business development needs in resources sharing,data migration and dynamic expansion.The emergence of distributed storage technology has gradually replaced the traditional storage solutions.Based on the application of the company's integrated office automation,this paper analyzed the problems faced by traditional storage solutions,explored the application of storage systems in data centers,and proposed a distributed storage solution based on Ceph.According to the demand,the application of distributed storage architecture based on Ceph in data center was designed,and realized the application of Ceph-based object storage,block storage and file storage system in data center.Finally,the performance of Ceph distributed storage was tested and optimized,and the results was also analyzed.The main designs were as follow:(1)To design the Ceph distributed storage architecture,from high I/O,high capacity and other aspects of the storage architecture was designed,and its function was tested and verificated;(2)To design the Network structure to improve the function of the Ceph distributed storage and make sure the security of the data center network;(3)The access rights and access to resources were controlled when the distributed storage providing sharing resources for different users,different businesses,owing to the unified authentication design of Ceph distributed storage;(4)Ceph distributed memory flow control design,limited the business system read and write I/O speed,for different business flow control to improve the stability of distributed storage platform;(5)Implementation and application of Ceph block storage,file storage and disaster recovery mechanism deployment in data center.Through the optimization of the above key technology,the test of storage performance,and finally applied it to the data center,improved storage resource utilization while reducing storage costs and meeting high-performance,high-capacity storage requirements.
