Massive Stripe Cache And Prefetching for Massive File I/O

This paper presents a massive stripe prefetching (MSP) scheme on a massive stripe cache (MSC) structure, which has been implemented in a Linux kernel. Our schemes efficiently perform on massive files such as audio/video files and a bulk of small files. MSC exploits spatial locality. MSP discriminates metadata reads and contiguous data reads in the stripe level, thereby boosting the read performance independently of a file-based prefetching.
