摘要
达梦数据共享集群(DSC)数据库中,任一程序包都可以在一组集群服务器上应用,并完成或者超过了造价极高的大型SMP计算机提供出的可伸缩及可用性的等级。达梦数据共享集群设计的可扩展和高可用的性能,借助保护应用能不被硬、软件的失败干扰,实现了系统的可用性,让数据得以进一步被访问。其水平扩展特性和垂直扩展特性形成了一个平台,保障了系统的稳定、安全。
In DSC database,any program package can be applied on a group of cluster servers,and can achieve or exceed the scalability and availability level provided by large SMP computers with high cost.The scalability and high availability performance of Dameng data sharing cluster design,with the help of protecting the application from the failure of hardware and software,realizes the availability of the system,so that the data can be further accessed.Its horizontal and vertical expansion characteristics form a platform to ensure the stability and security of the system.
