Prerequisites in a Production Environment

In this Lecture: We’re going to plan out your SCCM Hierarchy

• We’ll describe the prerequisites for installing SCCM.
• We’ll present an overview of the Hierarchy of Sites
• At the completion of this lecture, you’ll have a basic understanding of the requirements necessary to successfully deploy SCCM in your organization.

**Note: **Some thoughtful planning of the following points will be necessary before we can start the installation of SCCM.

• First, we must determine our site configuration. Should you set up a stand-alone primary a secondary or a Central Administration Site. We’ll talk about the differences between those three sites in a minute.
• Second, we must evaluate the needed server hardware configuration. Like how many CPU cores do I need, or how much memory, hard disk space.
• Third, we must procure the latest compatible revisions of the software. And that means what branch level of SCCM should I run, and which SQL version is compatible.

**Hierarchy of Sites **

What is a site?

A site defines the scope of administrative control.

A scope controls the objects that an Admin sees in the CM console and the permissions on those objects.

Objects could be users, computers, and servers.

When you install SCCM for the first time, you create a Configuration Manager Site.

This site is either a Stand-alone primary, a Secondary Site, or a Central Administration Site.

We’ll take a look at these three sites starting with the Stand-Alone Primary Site

Describe a Stand-alone primary site.

• This site is considered stand-alone because a single primary site can support the management of all of your users and devices.
• A stand-alone primary site is suitable for smaller deployments but can be expanded at a later time.
• A Stand-alone primary site has all of the System Center Configuration Manager components installed on one site.

SCCM components are the Site System **roles.…
