Abstract: Freeblock scheduling is a new approach to utilizing more of a disk's potential media bandwidth. By lling rotational latency periods with useful media transfers, 20-50% of a never-idle disk's bandwidth can often be provided to background applications with no e ect on foreground response times. This paper describes freeblock scheduling and demonstrates its value with simulation studies of two concrete applications: segment cleaning and data mining. Free segment cleaning often allows an LFS le... (Update)
