X-NAS (eXpandable network-attached storage) a scalable clustered file system designed for entry-level NAS has been developed. It enables centralized management of multiple NAS systems and virtualizes them into a single-file-system view for different kinds of clients. The core of X-NAS is a multi-protocol virtualized file system (MVFS) and its key feature ? a file-handle cache —improves the system scalability while maintaining X-NAS manageability. To evaluate X-NAS scalability an X-NAS prototype was designed and tested according to the NFSv2 implementation. These tests indicate that an eight-way X-NAS has a 10% faster response time and a 25% higher throughput than a conventional single NAS.
