Solaris 10 8/07 Installation Guide: Planning for Installation and Upgrade

System Requirements and Recommendations

Table 4–1 Memory, Swap, and Processor Recommendations

Requirement Type 


Memory to install or upgrade 

  • SPARC: 512 MB is the recommended size. 128 MB is the minimum size.

  • x86: 512 MB is the recommended size. 384 MB is the minimum size.

Note –

Some optional installation features are enabled only when sufficient memory is present. For example, if your system has insufficient memory and you install from a DVD, you install through the Solaris installation program 's text installer, not through the GUI. For more information about these memory requirements, see Table 4–2.

Swap area 

512 MB is the default size. 

Note –

You might need to customize the swap space. Swap space is based on the size of the system's hard disk.

Processor requirements 

  • SPARC: 200–MHz or faster processor is required.

  • x86: 120–MHz or faster processor is recommended. Hardware floating-point support is required.

You can choose to install the software with a GUI or with or without a windowing environment. If there is sufficient memory, the GUI is displayed by default. Other environments are displayed by default if memory is insufficient for the GUI. You can override defaults with the nowin or text boot options. But, you are limited by the amount of memory in your system or by installing remotely. Also if the Solaris installation program does not detect a video adapter, it automatically displays in a console-based environment. Table 4–2 describes these environments and lists minimal memory requirements for displaying them.

Type of Installation 


  • SPARC: 64–511 MB

  • x86: 384–511 MB


Contains no graphics, but provides a window and the ability to open other windows.  

If you install by using the text boot option and the system has enough memory, you are installing in a windowing environment. If you are installing remotely through a tip line or using the nowin boot option, you are limited to the console-based installation.

  • SPARC: 512 MB or greater

  • x86: 512 MB


Provides windows, pull-down menus, buttons, scrollbars, and iconic images.
