A Heuristic-based Real-Time Disk Scheduling Algorithm for Mixed-Media Workload

For mixed-media workload, disk scheduling strategies should meet the deadlines of requests with timing constraints while optimizing the disk utilization. To design a scheduling algorithm in mixed-media workload environment is very intricate because finding an optimal schedule is NP-hard as well as different QoS (Quality of Service) of each request should be guaranteed. In this paper, we present...

Apollon: File System Level Support for QoS Augmented I/O

Next generation information appliances are required to handle realtime audio/video playback and in the mean time should be able to handle text based requests such as database search, file recording, etc. Although several techniques are presented to address this problem, most of them are rather theoretical to be employed into practical systems as they are. In this paper, we present our experienc...

Clockwise: A Mixed-Media File System

This (short) paper presents the Clockwise, a mixedmedia file system. The primary goal of the Clockwise is to provide a storage architecture that supports the storage and retrieval of best-effort and real-time file system data. Clockwise provides an abstraction called a dynamic partition that groups lists of related (large) blocks on one or more disks. Dynamic partition can grow and shrink in si...
