In connection with the need of multiple heterogeneous platforms require to share disk space and provide a high performance read and write access of a large amount of data, this paper proposes a StorNext File System(SNFS)-based solution for building the highperformance data sharing system of the Chang'E-3 task ground application system. It expounds overall system architecture and implementation mechanism of data sharing and high performance read and write access to the heterogeneous platform, and focuses on ...
