16 Google Apps Connector for BlackBerry Enterprise Server Installation and Administration Guide
1. Google Apps to the Google Apps Connector
The Google Apps Connector synchronizes mail, calendars, and contacts through the Internet
to Google Apps.
2. Google Apps Connector to BlackBerry Enterprise Server
The BlackBerry Enterprise Server reads data from the Google Apps Connector provider for
any changes that should be sent to BlackBerry users. The component also writes any changes
to the Connector provider. The BlackBerry Enterprise Server is a server designed and
marketed by Research In Motion (the makers of BlackBerry) to support centralized
administration of BlackBerry devices for enterprise IT departments. The BlackBerry Enterprise
Server pulls information from the Google Apps Connector.
3. BlackBerry Enterprise Server to RIM Network
BlackBerry Enterprise Server connects to the Research In Motion (RIM) BlackBerry network to
send and receive messages.
4. RIM Network to Data Carriers
The RIM data network sends and receives messages from data carriers who support
BlackBerry devices.
5. Carriers to BlackBerry Users
The data carriers then connect to individual BlackBerry devices to send and receive data.
Capacity Requirements
Each server running Google Apps Connector for BlackBerry Enterprise Server is designed to
support up to 500 users. If you need to add more than this number of users, install additional
servers.
BlackBerry Enterprise Server Express is designed for small businesses and can be licensed
up to a maximum of 30 wireless users. If you need to support more than 30 wireless users you
should upgrade to BlackBerry Enterprise Server.
The exact number of users you can support depends on your server hardware and operating
system. For more information, see “Server Requirements” on page 19.
User Cache Files
When a new user is added, the Google Apps Connector initially caches up to 1000 past
messages in the Inbox/Sent labels, as well as all contacts and calendar events. The Google
Apps Connector will prune the user email cache so that only the past 30 days of email is
stored in the cache. Because of this caching model, expect to use about 1GB of disk space for
each cache file.
