Abstract
This presentation will describe the design of a cost-effective clustered NAS system using readily available off-the-shelf hardware and software components. The presentation will describe the underlying cluster technology, and show how it was adapted to provide scalable NFS and CIFS access to one or more file systems. Design choices throughout the development and the rationale for them will be presented, including a novel method for delivering scalable CIFS service that uses DFS technology. Performance, availability, installability, supportability, and the challenges of delivering a “software storage appliance” will be touched upon.
