Abstract：The issue research a key support technology and system approach that can provide many kinds of storage service for complex application environment. Its core is the dynamic organization and management of data resources and storage resourse. Its purpose is to support high-efficient storage service for open application environment with next generation of huge amounts of data and the issue can solve the data storage problem for complex application environment. In 2013， this project focuses on two systems， network RAID array and cluster file system . Four key technologies are made progresses， they are distributed asynchronous weak comparable versioning， high-dimensional redundancy， large-grained volume based metadata cluster and low latency client access of file system.

Key Words：Storage service；Qossafeguard mechanism；File system；Network RAID array
