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。 故障...

As part of the SQL Server AlwaysOn offering, AlwaysOn Failover Cluster Instances leverages Windows Server Failover Clustering (WSFC) functionality to provide local high availability through redundancy at the server-instance level—a failover cluster instance (FCI). An FCI is a single instance of ...
近期公司为了提高服务的可用性,就想到了部署AlwaysOn,之前的环境只是部署了SQL Server Failover Cluster,所以决定将云端放一台SQL Server来配置ALwaysOn,具体思路就是在本地的SQL Server Failover Cluster中再增加一个节点,然后将新家的节点放到Azure云端,然后在这两个实例之间配置AlwaysOn,部署后,有个问题就是集群...
点击Failover Cluster Manager 点击Validate Configuration… 点击Browse… 点击Advanced… 点击Find Now 选择SQL01,SQL02 验证完成后点击Finish,如下 输入集群名称:sqlalwayson,配置IP:192.168.0.110 去掉勾选 Add all eligible storage to the cluster 点击Finish,集群创建成功,如下 ...

The shared storage can be in the form of WSFC cluster disks, disks on a SAN, Storage Spaces Direct (S2D), or file shares on an SMB. This way, all nodes in the FCI have the same view of instance data whenever a failover occurs. This does mean, however, that th...
