I am about to embark on restructuring the network I look after which has a couple of physical servers (a PE2800 and a PE2900). The PE2800 is running SBS 2003 Premium and the PE2900 has Windows Server 2003 Enterprise installed.
The PE2900 also has Virtual Server 2005 installed and has 5 VMs installed (4 servers and 1 XP workstation). It has 18GB or RAM and a decent amount of storage.
That's the current scenario, what I'm looking to do is the following:
2 new PE R710 servers with roughtly 18GB of RAM; 2xQuad Core Xeon processors (in each server). These machines will be used to run the following:
Microsoft Dynamics CRM v4 Professional Server (2 organisations - 1 is a test one which has little to no access to it; the other has 50+ users);
Windows Server 2003 Enterprise (x4) - the previous machines from the VS2005 install mentioned earlier; these servers are only accessed by 2-3 members of staff at any one time and house back office software that is a mix of MS Dynamics GP10 and non MS software - each server housing it's own system indepenently;
A couple of VM workstations - probably running Windows 7 Pro but they will only be used sparadically for staff needing access to a machine from a remote location;
Each of the systems above also have MS SQL Server 2005 running on them (except the SBS machine and the workstations); the CRM Server currently has MS SQL Server 2005 with about 5 other instances on it as well. The SBS box will be running Exchange but we are looking to move to Office365 in the next 6 months.
I'm hoping this is enough info to go on but if not please let me know.
So I'm looking to determine the best way to setup the network (I know there's no definative answer here) but should I be setting the 2 R710 machines as Hyper-V workgroup machines and house all the other systems as guests (I'm looking to virtualize everything here)? Can they be setup as a cluster in a workgroup - should I even consider this for fallover? Am I best having them sitting on a domain (even tho the DC would be a guest upon them)?
All suggestions welcome here and material to read appreciated as I've not setup a Hyper-V before (although looks simple enough).
Thanx as always guys
