Abstract

An integrated multimedia file system supports the storage and retrieval of multiple data types. In this paper, we first discuss various design methodologies for building integrated file systems and examine their tradeoffs. We argue that, to efficiently support the storage and retrieval of heterogeneous data types, an integrated file system should enable the coexistence of multiple data type specific techniques. We then describe the design of Symphony -- an integrated file system that achieves this objective. Some of the novel features of Symphony include: a QoS-aware disk scheduling algorithm; support for data type specific placement, failure recovery, and caching policies; and support for assigning data type specific structure to files. We discuss the prototype implementation of Symphony, and present results of our preliminary experimental evaluation.
