Cluster Configuration Checklist

The following table helps you identify the environment settings you need to provide ScaleArc to create and configure the cluster. The asterisk (*) indicates which settings are essential to get ScaleArc up and running.

Some of the settings such as timeout values are required to tune ScaleArc for optimal performance. Review, complete, and save the table entries for future reference.
