Each AI server includes one or more install services. Each install service is set up to support an architecture (SPARC or x86) and a given OS release (such as Oracle Solaris 11.1 or 11.2). You might need only one or two of the possible options. For example, if you have only x86 clients but want to have the option of installing Oracle Solaris 11.1 or 11.2, you would need to create two install services, one service for each version of the OS. If you have both x86 and SPARC clients and want to only support Oracle Solaris 11.2 installations, you would create an install service for each architecture. See Creating an Install Service for more information.
