前言随着科技的发展,传统视音频技术和IT存储技术的融合越来越深入。从早期的DAS直连架构,到后来的NAS架构和SAN架构,乃至后来出现的IP-SAN架构,存储技术正在不断向前发展。同时,多年来的视音频存储系统集成经验也让我们彻底熟悉了各种架构的优势及劣势,也积累了一些使用中遇到的问题,诸如:后期扩展复杂,以及扩展后性能不升反降的问题。在这个信息爆炸的时代,大量非结构化数据的引入,正在逐步蚕食我们宝贵的在线存储资源,如何轻松的实现存储扩展?如何使视音 Preface With the development of science and technology, the integration of traditional video and audio technology and IT storage technology is more and more in-depth. Storage technologies are evolving from the early DAS direct-attached architecture to the later NAS architecture and SAN architecture, and the subsequent emergence of the IP-SAN architecture. At the same time, many years of experience in video and audio storage system integration have thoroughly familiarized us with the advantages and disadvantages of various architectures and also accumulated some problems encountered in their use. For example, the complexity of post-expansion is complicated and the performance of the system is not increased or decreased after expansion The problem. In this era of information explosion, the introduction of a large number of unstructured data, is gradually eroded our valuable online storage resources, how to easily achieve storage expansion? How to make video and audio
