Seer-SSD: Bridging Semantic Gap between Log-Structured File Systems and SSDs to Reduce SSD Write Amplification |
Abstract | ||
---|---|---|
Log-structured file systems (LS-FSs) sequentialize writes, so they are expected to perform well on flash-based SSDs. However, we observe a semantic gap between the LS- FS and SSD that causes a stale-LBA problem. When data are updated, the LS-FS allocates new logical block addresses (LBAs). The relevant stale LBAs are invalidated and then trimmed or reused with a delay by the LS-FS. During the time... |
