Design And Implementation Of A Distribute Object Storage System

In the era of the Internet, with the challenge of massive data, how to storedata efficient and security, becomes a hot topic in the field of distributed storagesystem. It is occuping an important position in the field of distributed storage that thestorage system based on object. Object storage system has been widely concernedby people for its scalability, reliability, safety and so on.In this paper, the design and implementation of an object-based storagesystem--COS (cloud object storage) storage system had been completed. Not onlyclients, metadata servers, object storage nodes, but also monitoring servers areincluded in the COS file system, compared with a general object–based storagesystem. In the COS storage cluster, metadata server want to ensure the security andefficiency of data access; object storage node in order to ensure the safety andefficiency of objects access of the cluster; the service running of cluster can bemonitored by monitor servers. File system has great advantages in many aspectsbased on the structure of the COS system, such as: high performance, reliability,scalability, security and high automation. The COS storage system provides a varietyof access methods for the convenience of users, including two kinds of client underWindows, Linux environment and a set of access based on Web interface.At present, the access pattern of multi tenant comes from most storage systemis implemented in logic. In the physical structure, data are stored in the same storagepool or disk, brings great hidden danger for safety and leads to the scenarios can notbe met by the storage system which need requirements of high security directly. Thestorage structure of a multi-level and multi domain completed in the COS storagesystem who based on distribution strategy of existing data. The data of different userscan be stored in different domain and the accesses between different user are limitedin the storage of COS.The main work of this paper:First, the storage system of COS is implemented; Second, the data can be distributed to the corresponding domain based on datadistribution strategy when in the data distribution;Third, the data security strategy is achieved in the storage system of multi-level andmulti domain.
