Preface
Microsoft System Center Configuration Manager is a book that covers all of the aspects from planning to deploying a redundant Configuration Manager environment.
What this book covers
Chapter 1, Planning for HighAvailability with Configuration Manager, covers what you need to plan for when you want to set up High Availability for your site. For instance, it shows how to plan a layout for SQL server, what kind of networking technology to use, and so on.
Chapter 2, Configuring Roles for High Availability, covers how you can deploy the different Configuration Manager roles that are highly available. For instance, it shows how we can deploy the application catalog service redundantly and the different forms of distribution points, and how they can affect the performance on our site.
Chapter 3, Deploy Highly Available Backend Services, covers how you can deploy backend services, such as DNS and AD that are highly available and how they operate together. It will also cover services such as SQL and using a redundant PKI solution.
Chapter 4, Backup and Recovery, covers what you need to take into account and how you can back up and restore a Configuration Manager environment. It also covers how the content store is built up and what we can use to back it up.
Chapter 5, Performance Tuning, covers various performance tuning tips such as OS deployment, virtualized environments, and SQL deployments. This chapter will also go into different OS tuning tips such as identifying bottlenecks using different tools.
What you need for this book
In order to try out the subjects covered in this book, it is recommended to download an evaluation version of Configuration Manager VHD from Microsoft, which can be found at http://www.microsoft.com/en-us/download/details.aspx?id=36428 contains a preconfigured Configuration Manager site with SQL and AD. It is also recommended to use a virtualized environment when evaluating technologies such as Hyper-V, VMware workstation, or Virtual box in a local environment.

Chapter 1. Planning for High Availability with Configuration Manager
Configuration Manager can be a complex solution to grasp, as it can span from thousands to tens of thousands of different clients placed all around the globe on different platforms. And with the large number of features it contains, it also requires a well-planned infrastructure in place to serve all the different clients.
The whole concept of a system being highly available is that a service (or services) will still be available to serve the users in case of a general failure of a single component or components in the infrastructure. If a system is not Highly Available and a critical component goes offline, your service might go offline, and depending on the priority and service level agreement (SLA) of that service, this situation might be damaging for the entire business and its users.
And of course you always want to plan ahead to make sure your solution is available at all times to serve your users. We will begin by going through the various components that makes up a Configuration Manager site and how they work to serve the clients.
In this chapter we will be covering the following topics:
Planning
When planning for High Availability you need to look at every aspect of your infrastructure; spanning from the underlying hardware to the software running on top of the different servers that serve the clients.
Some general points that can be highlighted when setting up a design and that need to be taken into account are as follows:
All these questions need to be taken into account and looked over, and taken into the planning phase. We always need to look over a design and think is there any single point of failure with this design? Because, it does not matter if we set up a massive and redundant SQL cluster in every way and we put the cluster on the same network switch. Because, then we know that if that particular switch goes down, the cluster goes down.
Coming back to Configuration Manager let us take a look at a simple site design for Configuration Manager and how it might look:
With a simple design shown in the previous diagram we have the general feature set for Configuration Manager available to our clients. All our Configuration Manager Clients will contact the Management point for policies, advertisements and reporting of data, and so on. The Management point in return will populate the site database with information received from the clients.
When the clients need to download a source file from an advertised deployment or for an operating system deployment it will contact the Distribution point within the site. For this site the data is stored in a single database server, which is collocated with the Primary Site Server. This design also includes a Software Update Point role as well as Endpoint Protection Role for the management of endpoint protection and patch management.
Let us look into problems with this type of design. For instance, let us see what would happen if the Management point server in the site stops functioning:
Let us see what would happen if we had two Management points in the site we just saw.
The clients would try to contact its first Management point; if it is offline it would look at its list of available Management points and try to contact the other one. This way we would have maintained site functionality for the clients. This gives us a Highly Available Management point solution for the clients, but this is only one of the components that need to be taken into account.
If the database stops working or suffers from a faulty hard drive at the server site, it would reflect outcomes that appear in the upcoming sections. As I mentioned earlier, clients will cache data locally until the site server is restored, but historical data will be lost. For instance, software metering information can be used for reporting licensing usage.
