Sample configuration
A sample setup is used to illustrate the installation and configuration tasks for two instances of SQL server, Billing and Payroll. During normal operation, one instance will be online on each of the two servers. If a failure occurs, the instance on the failing node will be brought online on the other server, resulting in two instances running on one server.
During the configuration process, create virtual IP addresses for the following:
-
Billing virtual server (virtual IP address is the same on all nodes)
-
Payroll virtual server (virtual IP address is the same on all node)
-
Cluster IP address
You should have these IP addresses available before you begin to deploy your environment.
The IP addresses are required only in case of IPv4. In an IPv6 network environment, the configuration wizards automatically generate a unique and valid IPv6 address based on the network prefix advertised by the routers.
The following table describes the objects created and used during the installation and configuration.
