Fast and failure-consistent updates of application data in non-volatile main memory file system
2016 32nd Symposium on Mass Storage Systems and Technologies (MSST)（2016）
摘要
Modern applications have their own update protocols to remain failure consistency. However, these protocols are implemented without a comprehensive understanding of the persistence properties of the underlying file systems and typically optimized for disk-based storage. As a result, they are complex, error-prone, and exhibit disappointing performance on emerging fast non-volatile memories (NVMs) due to excessive data copies.
