The main scenario is the high availability of databases. Compared with the Failover cluster image, it is highly available at the database level. In an image, you can use snapshots to separate read/write data. Log transmission: it is mainly u

A server cluster allows you to connect to many physical servers (or nodes) and serve as a failover partner for each other. The redundancy provided by the cluster gives you more uptime for your critical operations. During the 13 years of using SQL

Myth #11: Mirroring can fail over instantaneously after a fault is detected Error Failover of database mirroring can be initiated either automatically or manually. In the case of automatic initiation, a failover operation is performed by the mirror server (you are not mistaken, it is not a decision by the witness to fail over), both the witness and the mirror

Before you create a SQL Server 2000 failover cluster, you must configure Microsoft Cluster Service (MSCS) and use the Cluster Administrator in Microsoft Windows NT4.0 or Windows 2000 to create at least one
