Design And Implementation Of Object Storage System Based On Eucalyptus

Object-based storage is a new network storage model. It combines high performance of SAN and cross-platform of NAS. It moves 90% of the data management down intelligent storage devices, easing pressure of metadata server and file system. It is a breakthrough in scalability, security and intelligent storage of the system. Design object-based file system, with the object controller, condtitutes the object storage system and provides network storage services.Analysis the software framework of Eucalyptus, and suggest improvement for access component interface, network service level agreement and virtual network. Detailed analysis the storage component of Eucalyptus Walrus, provide the theoretical basis for replacement Walrus. Design object-based scalable file system: EXOFS. It is different from the traditional file systems. File management is no longer in the form of data blocks, but in the form of object. Object includes object attribute and data. Object attribute describe the information of object and data, store in the first of data area.Object includes big object and small object, can rational use disk space. Use incremental methods to increase object ID, coupled with a general-purpose identifier constitutes a complete object ID, can identify object ID easily. The results show that: disk IO of object storage system is fastern than Walrus. Disk space utilization of object storage system is improved by 10 percentage points.
