This information supplements the Adaptive Server 15.7 document Using Failover in a High Availability System > Configuring Adaptive Server for Failover on Windows.
Two Windows systems are required. Microsoft Cluster Server must be installed on both systems and they must be configured together as a Microsoft cluster. Sybase recommends that you set up and test failover of a simple application such as Notepad on the cluster to ensure that the basic failover capabilities of the cluster are working properly. All configuration must be performed from an account that has Domain Administrator privilege.
