The Solaris software is distributed on DVD or CD media so that you can install or upgrade systems that have access to a DVD-ROM or CD-ROM drive.
If you have systems that do not have local DVD-ROM or CD-ROM drives or if you are installing several systems and do not want to insert the discs into every local drive to install the Solaris software, you can set up the systems to install from remote DVD or CD images.
You can use all of the Solaris installation methods to install a system from the network. However, by installing systems from the network with the Solaris Flash installation feature or with a custom JumpStart installation, you can centralize and automate the installation process in a large enterprise. For more details about the different installation methods, refer to Chapter 3, Choosing a Solaris Installation Method (Overview).
Installing the Solaris software from the network requires initial setup. For detailed instructions on preparing to install from the network, refer to Chapter 12, Preparing to Install From the Network With CD Media (Tasks).
