Embedded Linux Used In Storage System

As the popularization of the broad band network and Internet, and the development of e-Government, e-Business, remote education, remote medical treatment and entertainment, the center of Information Technology industry has changed from information compute to information share. The field of great capacity data storage will be the fastest developed one. In new IT times, the storage device independent from general servers. It is smart enough that it can attaché to network directly. This kind device named NAS. Forecast by IDC, the saleroom of NAS market will increase from 540 million dollars in 1998 to 6.5 billion dollars in 2003, by 66.5% per year.This paper analyze storage technology such as DAS, NAS, SAN, and iSCSI, as well as embedded operation system can be used in NAS design. As a result, a new mini OS are designed base on Linux. It designed by code-level custom to a standard Linux system. This mini OS costs less storage space, with the function of storage management and network data sharing. Base on the mini OS, a NAS device with basic function are designed and test. The test result show the perfect performance of network data sharing.The paper includes the research and analyze of storage market and technology, the design of embedded OS and the design process of a new storage product.
