The fifth special topics issue of Operating Systems Reviews will be related to File and Storage Systems and Erik Riedel (erik.riedel @ seagate.com) will be the guest editor. For this issue, we seek submissions on all aspects of file systems, storage systems and storage devices. This includes large-scale or Internet-scale storage systems, data center storage, and personal storage. Short overviews of mature projects and experience reports are welcome, as well as papers outlining nascent ideas for new directions, and everything in between. Topics of interest include: - principles for self-organizing storage systems - storage security and data privacy - redefinition of storage services for large-scale storage - robust, fault-tolerant and self-healing storage - experience with novel storage-intensive applications - experience with deployed large-scale storage - new problems and novel contexts for file or storage systems Papers will be reviewed by the guest editor with the assistance of outside referees. The primary criteria for acceptance are broader interest to the systems community, potential consequences for systems builders and clarity of exposition. Position papers are welcome, as are short (1- to 2-page) notes ("rants") on commonly encountered problems with today's systems or ongoing storage-related work. This special issue does not have a predefined format or a target number of accepted papers, but there is a soft cap of roughly 84 pages of text devoted to papers. Papers should be double column including figures and tables in standard ACM format and submitted as printable PDF. If you are interested in submitting to this issue of OSR, please send email to erik.riedel @ seagate.com with a brief description of your submission by November 1, 2006. The final submission will be due November 15, 2006.
