Proximity to messaging and collaboration servers
The BlackBerry Enterprise Server should have access to messaging and collaboration servers through a local,
high-speed, switched network connection. For a decentralized server topology, consider the physical link speeds
between the sites and the geographical placement of BlackBerry users. RIM recommends that you place the
BlackBerry Enterprise Server as close to the messaging servers as possible and target the messaging servers that
host the majority of BlackBerry users. Depending on the WAN infrastructure, you might want to implement a
BlackBerry Enterprise Server in more than one site for optimal performance.
BlackBerry Desktop Software connection
If you use the BlackBerry Desktop Software, a network connection to the BlackBerry Enterprise Server and the
messaging server must be available.
Internet connection
The BlackBerry Enterprise Server requires an outbound-initiated Internet connection on port 3101. Any firewall
that is placed between the BlackBerry Enterprise Server and the Internet must allow this connection. You must
also verify that you have enough Internet bandwidth to manage the additional traffic that the BlackBerry
Enterprise Server generates. Messages are sent to BlackBerry devices in 2-KB sections; however, because of
compression, only 1 KB goes through the Internet connection.
