“…Atomicity and Durability We will investigate how the in-storage address-remap command can be exploited to accelerate various performance-critical operations in F2FS such as checkpoint, fsync, and atomic write. For example, RM-IPU will enable to achieve the atomic propagation of multiple blocks with less DRAM resource and storage than the existing implementation in F2FS [4]. It is also worth investigating whether RM-IPU can easily support transactional features such as multi-file updates, shadow garbage collection, and stolen pages [1], with minimal change in F2FS codebase.…”

While gaining popularity in mobile devices, F2FS, a flashfriendly variation of log-structured file system, reveals three drawbacks: segment cleaning overhead, metadata update overhead, and file fragmentation, which becomes conspicuous under random update workloads. This paper suggests for the first time to leverage the address-remap technique in flash storage to remedy such pitfalls in F2FS. Our approach can, while preserving the benefit of log-structured writes, achieve the eventual effect of in-place update, completely preventing three drawbacks of F2FS. It can thus significantly outperform ext4 as well as vanilla F2FS under random update workloads. Armed with another write mode, F2FS will become competitive for a wider range of applications.
