{ZMS}: Zone abstraction for mobile flash storage
JY Hwang, S Kim, D Park, YG Song, J Han… - 2024 USENIX Annual …, 2024 - usenix.org
We propose an I/O stack for ZNS based flash storage in mobile environment, ZMS. The zone
interface is known to save the flash storage from two fundamental issues which modern flash …

The dilemma between deduplication and locality: Can both be achieved?
X Zou, J Yuan, P Shilane, W ** for persistent memory
Persistent main memory (PM) dramatically improves IO performance. We find that this results
in file systems on PM spending as much as 70% of the IO path performing file map** …
