A Embedded Linux-based Nas Model

With fast development of computer technology and network application, theinteraction of information is becoming more and more frequent and the need ofstorage capacity is much bigger. Storage has become a special part in IT fields. Howto build a new architecture and improve security of storage data, even how to speedto access data in disk are all the problems we must solve as fast as possible. In thepaper, we propose a new business application about NAS, which is an approach toport NAS into embedded Linux for storage in Home Network.In it, we may storeand manage multimedia data in same platform, then control the data which differentusers want to access through different hardware. Because data storage is attachedinto network, devices in network will be able to access data. It is useful to buildfuture information society. The focus of the paper is NAS system architecture andmethod related with embedded Linux.The most important research is the procedureof porting NAS system into embedded Linux.Clue for this paper is described as below:In the first part, we compare several well-known network storage technologies,analyse the architecture of NAS, including component of software and hardware andhow to consist of network protocol stacks, research the improvement with thearchitecture in details.Then we discuss the concept of embedded system and embedded Linux system,analyse how to tailor Linux kernel. And then in terms of project, we introduced keymechanisms for XFS to make performance optimization.Then we come to the most important chapters in this paper. In these chapterswe told readers how to build a complete system application. We propose a solutionincluding glossary design, configurating services, system management andperformance test.Finally, summary is taken for this paper, advantages and disadvantages of thesolutions are indicated with suggestions given for further research.
