A Case Study of OSS/COTS-Based System Development: Design and Implementation of an Open Scalable Network Storage Attached System

In the past decade researchers have been interested in building system based on the Open Source Software (OSS) or Commercial-Off-The-Shelf (COTS) more and more. Since most of functions are provided by the OSS/COTS how to choose the suitable components has to be the first issue. Now there are some models targeted this problem but we think most of existing models are impractical. Finally, in this paper we design and implement a network attached storage system as typical case study about system development based on OSS/COTS and we focus on these problems: evaluation and choice of available OSS/COTS for system with a definite requirement.
