This Post is in Continuation with Part # 2 , where we explained about a simple SCCM Architecture . In this Example , we will take a closer and more granular look at Primary Site :

One of the important point in SCCM 2012 is that it supports a Maximum of 25 Primary sites Per Hierarchy . Now , the reason for this restriction is that Microsoft has tried a lot to make sure that we do not use Primary Site for most common reasons listed below :

1. Support for Multiple Language : There is no need to have Different Primary Sites to support Multiple Langues . SCCM 2012 supports Multiple Language .

2. Client settings are now applied at the collection level and not at the primary site

3. With RBAC , Role Based Access Control , you can now delegate Roles Easily . Like you can have a Admin for Managing Servers and one for Clients .

Some of the reasons where you Might Need SCCM Primary Site are :

 Political reasons , Load Balancing , Reducing the Impact of Primary Site Failure ,

This Post is in continuation to Post # 1 on SCCM Design and Architecture .

Now , As we have seen that in our SCCM Design we have :

With these Specifications let us Design our SCCM Environment :

Server Names : One SCCM Server ( sccm.abctelecom.com) , Domain Controller ( abctelecom.com ) , Role Server ( sccm1.abctelecom.com) , 4 Distribution point Servers)

Today,  in this post we will see how to design a SCCM Environment . Using this post you may design your  SCCM design document . To create a SCCM Environment , it is very important that we have some detailed information . For the sake of simplicity , we will use a simple example here .

SCCM Design

Let us Assume that we are being asked to design , architect and implement  a sccm ( System Center Configuration Manager 2012) environment with following specifications :

1. The Client has presence in 5 states of India .

2. Total user base is : 5000

3. Head office is in Mumbai : with a user base of : 4000

4. at the head office the number of servers to be maintained using sccm is : 100

4. Four Other offices are in : Bangalore , Kolkata , Delhi and Himachal .

5. User base at all these four locations is : 250 each .

6. There is a 4 Mbps connectivity between branches ( all of them ) .

7. The link utilization is below 50 % on an average during office hours and is 30 % off hours

8. Client wants to use all the features of SCCM ( OSD , Patch management , Software deployment etc ).

9. There is just one forest and one domain Ex : abctelecom.com

10 . Internet clients are not a part of this project

11. There are no cloud DP’s .

The above information is handy enough to kick start our designing :

Now , To start with , we have to make a decision as to how many sites we require : or you may ask the following questions to yourself :

1. How Many SCCM Primary Sites do I need :  In this case since the total Client base is just 5000 .  Since with SCCM 2012 we can clearly divide work between engineers who manage Servers and clients .

2. Do we need a CAS :  NO . CAS in SCCM 2012 is only used for Centralized repository and reporting .

3. How Many Secondary sites do I need : This is a very Tricky Question and this is where a lot has changed between SCCM 2007 and SCCM 2012 . SCCM 2012 DP can be used for PXE i.e OSD , Throttling and Scheduling . So , We would only need DP’s in our case as the bandwidth available is also good .

See the below blog posts for more clarity :



Now , that we are sure that we need just One Primary and Distribution Points only , Am done with my first part .

So , so far our design looks like : 1 Primary stand Alone site and 4 Distribution Points at 4 different locations .

I close this post here and will take things in more details in the Part 2 of this series .
