Installation Memory Requirements

If you are running a Solaris Express Community release or an OpenSolaris release, the minimum memory requirements to install a system is 512 Mbytes of memory.

For the Solaris 10 release, the minimum memory requirements to install a system have been increased from 256 Mbytes of memory to minimum of 384 Mbytes of memory. This amount of memory enables a text-based installation only. To run the installation GUI program requires a minimum of 768 Mbytes of memory.
