The installer runs a check to determine if your host has sufficient memory and disk space for the components you selected.
If the memory found on the host does not satisfy Communications Suite recommendations, the installer displays a warning. Installation can proceed, but you should upgrade memory later.
If the disk space or swap space found on the host is insufficient, the installer cannot proceed. You must resolve the problem before you can resume the installation.
On Solaris 10, memory check is not performed if you are installing into a non-global zone.
