中继卫星系统地面云存储架构设计

针对中继卫星系统日益增长的海量数据存储需求,探索将云技术应用于中继卫星地面存储系统中,研究并设计了适用于中继卫星系统的分布式云存储的体系架构.该架构通过分布式存储和存储虚拟化技术,对存储资源进行了整合,将分布在不同地理位置上的存储网络,集合成一个大规模广域云存储系统,可提供整体存储和访问的功能,并实现对数据的高效“存”、“取”、“管”.与传统NAS(Network Attached Storage,网络附加存储)架构分析比较,该架构从系统扩展性、可靠性和服务性等多个方面均更加具有优势,能够适应日益增长的中继卫星系统海量数据存储需求,解决中继卫星系统中大容量数据存储的瓶颈.

Design of ground cloud storage structure for the tracking and relay satellite system

For mass storage data storage of the Tracking and Data Relay Satellite(TDRS) system, cloud storage technology is applied to the ground storage.We studied design of the integrated, distributed cloud storage architecture and implementation method to solve large capacity data storage of TDRS system, which can adapt to the growing need for mass storage.The distributed storage and storage virtualization technology is applied to integrate storage resources using distributed storage network in different geographical locations, that can set a large scale wide area cloud storage system and provide the overall storage and access functions to save and control data efficiently.Finally, the design of the cloud storage architecture is better than the traditional Network Attached Storage(NAS) architecture in terms of system scalability, reliability, service and other aspects.
