Abstract

Recent advancements in flash-based solid state drive (SSD) make it a highly desirable storage device, especially for data-intensive applications. There are significant more SSDs used in data centers and high performance computing systems. SSDs perform one or two orders better than traditional hard disk drives generally. However, the performance of random writes on SSDs, especially small random writes, is still largely limited due to the garbage collection (GC) process. Existing work tried to utilize the on-device RAM as a write cache to improve the write performance, however directly utilizing it as a normal write cache under utilizes the RAM cache. In this poster, we present our initial study of a cache management scheme that hides the GC latency.
