How To Use This Chapter

Data centers have unique requirements, constraints, and network topology. It is likely you will have multiple challenges when creating a total solution for system installation and recovery, which will require you to implement multiple solutions for your site.

To help explain network topology, an example complex network diagram will be used that presents multiple challenges. This example network will be referenced throughout the complex networking chapters.

Knowledge of network boot and OS installation steps will help you understand this chapter. Most often, boot and installation is performed by one server. When considering complex network solutions, it sometimes make sense to use separate systems for boot and installation, or to switch servers during the boot process. See the “How Ignite Works” section for network boot and OS installation steps information.

Network boot and installation relies on several protocols that are not detailed here. See “Ignite-UX Server Ports” for protocol and port information related to Ignite phases of operation.

It is assumed you have a working knowledge of DHCP, PXE, bootp, and TFTP.
