Disk Space and Memory Requirements for Custom and Express Installations

A typical production environment requires four servers.

The following tables identify installation options, recommended memory requirements, and installation locations. Disk space requirements for each server depends on the components you install.

Although all components are selected by default, you can choose the components to install. Select group packages, individual items, or a combination of the two.
