水利科研云平台建设与总体设计应用的主要技术研究

为持续推进水利科研信息化进程，开展了水利科研云计算平台体系及其应用技术研究，明确了管理云、科研云、办公云、综合数据中心及智慧流域研究平台支撑这5项应用需求;采用主流的X86系统架构，运用虚拟化技术，实现资源池化的技术路线，完成云平台结构设计;在统计现有设备使用率和各项应用预期数据的基础上，计算得出平台资源池的规模并确定设备档次;汇总VMware等主流软件调研成果，比选确定了云操作系统。并就水利科研云平台的云运行模式、云存储模式、云安全问题开展技术研讨。按照设计，云平台基础设施已经建设并得到有效使用，有关应用工作也正在有序推进。

Technological Study on Cloud Computing System and Its General Design for Water Scientific Research

In order to accelerate informatization of water-conservancy scientific research, we study the cloud computing system and applied technologies for water scientific research, and 5 demands for cloud computing application in management, scientific research, office automation, integrated data center and intelligent river basin research are demonstrated; the architectural design of cloud computing system is completed with adoption of the prevailing X86 architecture and the virtualization technology for resource pooling; the scale of resource pool and the grade of equipment are obtained according to the current equipment utilization and the calculation results of 5 demands; and the cloud operation system is determined by comparison. The technical discussion on operation mode, storage mode and safety of cloud computing system for water scientific research is carried out. In association with design, the infrastructures of cloud computing system has been established and put into operation, and relevant applications are promoted in an orderly way.
