Abstract

Storage swapping has been a critical technique used to relieve memory pressure and improve user experience. However, it generates lots of data writes in flash storage, deteriorating the lifetime and performance. In this paper, inspired by empirical studies on swap data access characteristics, we propose a novel data invalidation scheme, namely DISS, which includes two methods. First, a cross-layer swap-data invalidation method is proposed to invalidate swapped-in data at a low cost. Second, a swap data separation method is proposed to schedule swap data and file-backed data into different places. Experimental results show that DISS achieves encouraging flash lifetime and performance optimization. © 2025 Copyright is held by the owner/author(s). Publication rights licensed to ACM.
