Clustered File System
A clustered file system is a type of file system that is shared by being mounted on multiple servers concurrently. There are quite a few approaches of clustering, most of which do not utilize a clustered file system. Clustered file systems can offer few convincing features including location-independent addressing and redundancy. It improves reliability and reduces the complexity of the other parts of the cluster. Parallel file systems are a type of clustered file system that distributes data across multiple storage nodes, usually with the purpose of redundancy or improved performance.
