军用云数据中心数据库服务双活系统架构

Architecture of Dual-active System for Database Service in Military Cloud Data Center

提出一种军用数据中心双活容灾抗毁解决方案,建立了数据库双活系统技术架构,描述了系统的 基本组成和功能。提供一种同城双活军用数据中心系统网络架构,描述了计算节点、网络节点、存储节 点等连接关系。同时,提出了数据库服务仲裁管理机制,深入分析了数据中心级故障和链路故障下,数 据库双活服务能力。最后,基于典型军事应用验证系统,构建了最小规模的数据中心双活系统,验证了 双活系统架构的有效性。

In this paper, a dual-active disaster recovery and anti-destruction solution for military data center is proposed. The basic composition and function of the system are described by the technology of establishing the architecture of dual-active database system. The connection relationships among computing nodes, network nodes and storage nodes are described in the network architecture of dual-active system military cloud data center system. This pater proposes the arbitration management mechanism of database service, and deeply analyses the dual-active service capability of database under the condition of data center level failure and link failure. Finally, based on the typical military application verification system, a minimum-scale data center database dual-active system is constructed, which verifies the validity of dual-active system architecture.
