Determining How Many Ultrasound Environments to Install

An Ultrasound environment is a controller and database that are configured to communicate only with each other. The paired controller and database can monitor a single replica set or multiple replica sets. Use the following guidelines to make your choice:

Use a separate Ultrasound environment for each replica set if you have a combination of these factors:

• Your organization has numerous replica sets that are geographically dispersed.
• The replica set you want to monitor consists of a group of servers that are not part of other replica sets.
• You want to keep the database size smaller.

Use a single Ultrasound environment to monitor multiple replica sets if you have a combination of these factors:

• Your organization has a small number of replica sets.
• You want to monitor multiple replica sets that exist on the same group of servers.

If you decide to use multiple Ultrasound environments, the controller for each environment must be installed on a separate computer and use a different database name, though you can use the same database server instance.
