In this chapter, you learned how to identify and configure site systems for your SMS site. The site server can be assigned all site system roles, of course, and in many environments this may be appropriate. However, other concerns might cause you to assign one or more site system roles to other servers in your site. These concerns, as we have seen, include performance limitations of the site server, the number and location of clients and users, network infrastructure, and network traffic patterns. Now that you understand how to manage systems within your site, we can explore the process of joining different SMS sites in an enterprise-wide site hierarchy—the topic of Chapter 4.
