Preparing for SCCM

 As I have said in the past SCCM is a beast there are a lot of moving parts needed to make the system work. When you plan on installing SCCM you should take some time and step back to look at how you want your system to be set up. SCCM much like Active Directory can have multiple sub sites as apart of your primary site. In most cases you will only have a single site. An example of a user for multiple sites would be if you work at Food.inc and Food.inc owns Meat.inc, Veggie.inc and Grain.inc You could set up a Primary Site Server for Food.inc and a child Site server for each sub company.

When you start to look at what hardware you are going to need you should be looking at Microsoft SCCM recommendations page. However since Microsoft doesn't always do a good job of always keeping information on there site I have a PDF version of the page saved. Below is a table right from the PDF that will help you to determine what you are going to need to set up your own site.
