You can install all BlackBerry® Enterprise Server Express components on one computer, or you can install specific components on separate computers. You should consider any impact to system resources before you decide where to install the components.

You install all components on one computer if you do not plan to activate many BlackBerry devices, if you determine that the computer can manage the volume of traffic for the BlackBerry Enterprise Server Express components, and if it is acceptable that the computer has direct access to the Internet without being located in the DMZ.
