Research in integrated file systems - file systems that support different types of data and applications with diverse performance requirements - has stagnated since the commercial failure of video-on-demand systems in the 1990s. However, the past two years have seen an acceleration in the development and deployment of several new techniques aimed at web-based multimedia applications. These technologies have opened up a fertile research ground for new file system optimizations and rekindled interest in multimedia file systems. In this paper, we describe some of these technology trends, examine their implications on file system design, and present a sampling of the new research problems that arise due to these technological changes. Based on these observations, we argue for a renewed effort in designing next-generation integrated file systems.
