随着大数据技术的飞速发展，数据中心机房的规模不断扩大，IT设备数量不断增加，分散型的传统数据中心已无法应对虚拟化、集中化、高密化等服务器发展的趋势，以集装箱式、模块化式为代表的数据中心正逐渐成为当今发展的潮流。以阳城县大数据中心为例，从应用的角度阐述模块化数据中心架构，华为FusionModule智能微模块以及实际部署情况，以期为各地区开展大数据中心建设提供思路。

With the rapid development of big data technology, the scale of the data center computer room is expanding, the number ofIT equipment is increasing, and the decentralized traditional data center has been unable to cope with the trend of server develop-ment, such as virtualization, centralization, high density and so on. Taking the big data Center in Yangcheng County as an example,this paper expounds the modular data center architecture, Huawei FusionModule intelligent micromodules and actual deploymentfrom the point of view of application, in order to provide ideas for the construction of big data center in various regions.
