Increasing Distributed Storage Survivability With a Stackable RAID-Like File System

This paper has designed a stackable file system called Redundant Array of Independent File-systems (RAIF). It combines the data survivability properties and performance benefits of traditional RAIDs with the unprecedented flexibility of composition, improved security, and ease of development of stackable file systems. RAIF can be mounted on top of any combination of other file systems including network, distributed, disk-based, and memory-based file systems.
