10 Google Calendar Connector for Lotus Notes Installation and Administration Guide
Topologies
The Calendar Connector database can be installed and configured differently depending upon the size and
spread of your Domino environment.
Option 1 - Single server/site implementation
Where all Domino mail servers exist at one site you will install the Calendar Connector database onto a single
server in your organization. This server will be solely responsible for:

Acting as the web service provider for incoming Google to Notes lookups.

Acting as the polling server, polling Google Calendars and updating the Notes busy time stores for Notes
to Google lookups.
This server will reach out to any other server in your organization to obtain and to update free/busy
information as required by each of the two services.
Option 2 Multi server/site implementation
Where mail servers are located across multiple sites/time zones you should install an instance of the connector
at each site. In this configuration:

One instance acts as the web service provider for incoming Google to Notes lookups.

Each instance acts as a polling server for users whose mail servers are held at that site. This allows the
polling services to be shared across multiple servers offering optimum performance.
Note: It is important that each instance of the connector is installed separately. Do not replicate the connector
across multiple servers.
