This paper presents storage implementations that utilize the Lustre file system for CMS analysis with direct POSIX file access while keeping dCache as the frontend for data distribution and management. We describe two implementations that integrate dCache with Lustre and how to enable user data access without going through the dCache file read protocol. Our initial CMS analysis job measurement and transfer performance results are shown and the advantages of different implementations are briefly discussed.
