Block I/O serves as a classic interface for accessing storage devices with portability. But it can also cause extra overhead by enforcing transferring data in the unit of blocks. In this paper, we present CoinPurse, a device-assisted file system with dual interfaces. By leveraging non-volatile memory (NVM) in SSD, CoinPurse manages to adaptively persist writes through both the block I/O and a byte-addressable partial update interface. In addition, we also develop a set of techniques to overcome hardware limitations and resolve possible consistency conflicts. Evaluation shows that CoinPurse outperforms F2FS, a popular flash-optimized file system, by up to 33.2%. |
