故障转移群集(Failover Cluster Instances)和AlwaysOn是SQL Server中两种不同的高可用性解决方案。它们在实现高可用性的方式上有一些显著的区别: 故障转移群集(Failover Cluster Instances): 故障转移群集是一种基于 Windows Server 故障转移群集技术的解决方案,它使用共享存储并在主节点和辅助节点之间进行故障转移。
5. 添加SQL Server 到Failover Cluster 安装完成后,使用以下PowerShell命令将SQL Server 添加到Failover Cluster: Add-ClusteredSqlServerInstance -InputObject (Get-Cluster) -InstanceName "SQLInstance" -Name "SQLServer" -IPAddress "192.168.1.10" -SubnetMask "255.255.255.0" 1. 这个命令会将SQL Server 实例...

Applies to: SQL Server SQL Server Always On failover cluster instances use Windows Server Failover Clustering (WSFC) to provide local high availability. A failover cluster instance (FCI) is redundant at the server-instance level. An FCI is a single instance of SQL Server th...
On a Linux Pacemaker cluster, each SQL Server FCI needs its own unique IP address and name. If the FCI configuration spans multiple subnets, one IP address is required per subnet. The unique name and IP address(es) are used to access the FCI so that applications and end users don't ...
1.2 安装 windows server failover cluster 1.2.1 这里需要特别指出,因为在这里耗费了大量的时间: 首先,我是创建了个 windows server 2008r2 的 VM, 然后拷贝 2 份当做 cluster node. 本来图个方便用 domain administrator 账户来配置 failover cluster , 结果提示不能 load 拓扑。就是传说中的 ox80070005,看...
