Stackable Fan-Out File Systems

Stackable fan-out file systems are file systems that can access more than one lower file system at once. Fan-out file system can therefore offer interesting applications such as unification, load-balancing, replication, failover, sand-boxing, and more. Fan-out file systems are particularly useful in the data grid area. However, operating systems are not designed to easily support fan-out file systems. In this project we develop OS infrastructure for stackable fan-out file systems as well as several practical fan-out file systems, addressing issues such partial failures, rollback of operations and state, and interaction with existing and new applications. We consider the ramifications of maintaining Unix semantics vs. enhancing the Unix API to support our advanced file systems.
