CloStor: A Cloud Storage System for Fast Large-Scale Data I/O

摘要

Non-structured and semi-structured large-scale data storage has become a hot research topic. This paper has, through analysis and research on the fast I/O mechanism of large-scale block data, designed a fast data access mechanism. The system can achieve efficient storage of large-scale small files, reduce the I/O frequency of metadata control information, improve the storage and access performance of small files, reduce the memory utilization of metadata and maximize the number of files supported by the system; meanwhile, the system can enhance the storage performance of large files by providing such files with high-speed parallel access interfaces.
