新一代遥感数据中心建设的关键技术

Key Technologies for Construction of New-Generation Remote Sensing Data Center

为满足大型业务发展需要,建设新一代数据中心已成为一种共识。根据国际正常运行时间协会(UI)的划分,数据中心从基础级、冗余部件级发展到可并行维护级和容错级,其可用性和可靠性得到明显提高。针对大容量遥感资料对于数据传输和处理高时效、系统计算负载和存储容量高增长的要求,在研究新一代数据中心(NDC:NewDataCenter)六大关键技术的基础上,重点对自动化动态资源部署、优化资源的利用效率、统一的基础设施管理、完善的资源和数据保护、信息技术架构的可扩展性、节能技术和产品等方面进行了应用与实践,促进了新一代遥感数据中心的成功建设。文章结合新型气象卫星风云三号地面系统的建设实践,阐述了新一代遥感数据处理中心建设中若干关键技术的实现方法。

To satisfy the sustainable operation development,the establishment of new-generation data centers has becoming a common sense.According to the definition of the Uptime Institute（UI）,the availability and reliability of data centers will be improved obviously when they evolve from basic,component redundancy level to the concurrently maintainable and fault-tolerant level.To meet the increasing demands on the time effectiveness for the large volume of remote sensing data transmission and processing and the fast growing requirements for system computing and storage capabilities,the six key technologies for the New-generation Data Center（NDC） are investigated.Based on these technologies,the application and practice put their emphases on the dynamic resource deployment automation,resource effective usage optimization,unified infrastructure and facilities management,solid resource and data protection mechanism,scalable information technical architecture,energy conservative or green computing technologies,product adoption,etc,which will facilitate the successful construction and operation of a new-generation remote sensing data center.In combination with the implementation of the FY-3A ground application system,the best practice is presented for the implementation of six key technologies to set up a new-generation remote sensing data center.
