摘要:
随着气象业务技术体制的调整,对气象数据中心的连续稳定运行提出了更高要求,利用虚拟化、分布式、数据备份、业务容灾等多种先进技术,提高硬件资源利用率和软件资源复用率,增强业务系统抗风险能力。 数据中心含众多服务器和异构计算资源,引入虚拟网络、虚拟存储、CBT 变化数据跟踪等技术、方法,可有效确保系统运行可靠性。 在气象监测预报预警支撑系统中,采用 VMware 的异构虚拟化特性将不同类型的存储进行集中统一管理,简化了系统复杂度,使用vMotion 技术实现虚拟化平台的高可用性;数据存储系统采用 RAID2. 0+块虚拟化架构,实现存储系统负载均衡和性能的提升。 该文主要叙述利用 VMware 和灾备技术,通过对异构存储进行虚拟化和负载均衡部署,实现一体双活,保障气象业务数据的安全性,提升数据服务的效率。 系统在业务中应用后,提高了计算资源、存储资源的利用率,实现了资源的按需分配,提高了服务器、存储资源的管理效率,数据的安全性和高可用性。
Abstract:
With the adjustment of the meteorological service technology system, higher requirements have been put forward for the continuous and stable operation of the meteorological data center. By using many advanced technologies, such as virtualization,distribution,data backup,business disaster recovery and so on,the utilization rate of hardware resources and the reuse rate of software resources are improved,and the ability of business system to resist risks is enhanced. Data center contains many servers and heterogeneous computing resources. The technology and methods of virtual network,virtual storage and CBT change data tracking can effectively ensure the reliability of the system. The heterogeneous virtualization characteristics of VMware are used to manage different types of storage in meteorological monitoring, forecasting and early warning support system, which simplifies the system complexity and uses vMotion technology to realize the high availability of virtualization platform. Data storage system adopts RAID2. 0 block virtualization architecture to realize load balancing and performance improvement of storage system. We mainly describe the use of VMware and disaster recovery technology,through the storage of heterogeneous virtualization and load balancing deployment, to achieve one dual live, ensure the security of meteorological business data and improve the efficiency of data services. After system application in Ningbo meteorological business,the utilization rate of computing resources and storage resources is improved,the distribution of resources on demand is realized,the management efficiency of server and storage resources is improved,and the security and high availability of data are improved.
