You can customize the configuration of the servers that are required by WAN boot to meet your network needs. You can host all the servers on one system, or place the servers on multiple systems.
Single server – If you want to centralize the WAN boot data and files on one system, you can host all the servers on the same machine. You can administer all your different servers on one system, and you only need to configure one system as a web server. However, a single server might not be able to support the volume of traffic that is required for a large number of simultaneous WAN boot installations.
Multiple servers – If you want to distribute the installation data and files across your network, you can host these servers on multiple machines. You might set up a central WAN boot server, and configure multiple install servers to host Solaris Flash archives across your network. If you host the install server and logging server on independent machines, you must configure those servers as web servers.
