Hi Team,
[Apologies for a long question]
I am working on designing a SCCM 2012 R2 SP1 for our organization. We have about ~6000 clients across multiple locations. There are three major locations US, India and Europe and there are 5 micro sites in APAC region.
US and India has about 2500 clients each
Europe has 600 clients
APAC has about 200 clients
All the three major sites have good WAN link and its working fine for our existing SCCM 2007 setup (CAS & 1 Primary in US, 1 Primary in India and 1 Secondary in Europe)
Now the design i am proposing is 1 Standalone primary in US, 1 DP /w PXE or secondary in India, 1 DP /w PXE in Europe. Other micro sites in APAC can have DP /w PXE for OSD reasons.
NOW, there is another suggestion in the org to have a CAS in US, 1 Primary in US, 1 Primary in India, 1 DP /w PXE in Europe and micro sites in APAC can have DP /w PXE for OSD reasons.
The problem is i am not sold on introducing the CAS for the reason that we have only ~6000 clients and don't expect a exponential growth in clients in next 3-4 years. I am being told that if our stand alone primary fails, this can put us in trouble. to protect us from such situation we can introduce a CAS, 1 primary in US & India regions so that in case of a primary server failure in US, clients can redirect to India primary server.
I would like to know the suggestions from this forum on how feasible this proposal is and is it necessary to have a DP /w PXE for sites which have fewer than 20 clients for OSD?
Thanks.
