We want to setup a "small" server for on of our offices (8 Client Computers, local Domain not linked). We need to have an Exchange Server. Unfortunately we cannot use SBS since its support is running out.

We already do have a Windows Server 2012 R2 Essentials Licence and an Exchange Server 2013 Licence (+CALs).

As Exchange does not run on Essentials (thanks Microsoft for that!) we need to run a Standard Licence.

My Setup would be the following:

  • Host Machine Windows Server 2012 R2 Standard with Hyper-V on it
  • 1 Virtual Machine Running Windows Server 2012 R2 Standard + Exchange Server
  • 1 Virtual Machine Running Windows Server 2012 R2 Essentials (Domain Controller)

As Microsoft does not recommend running the domain controller on the same instance as the Exchange Server and we do have less than 25 Clients i would go for that setup. Seems a bit over complicated but as far as i understand it follows Microsoft's recommendations.

Do you have any recommendations concerning the hardware? Right now we have a Lenovo RD340 equipped with 8GB RAM, 1 SSD 128GB and 3*3TB HD in Raid 5. Maybe we should upgrade it to 16GB RAM, but as the Hyper-V can manage the required memory it could be enough right now. Where should we install the Guest VMs? On the SSD?

In a situation this small I'd disregard that recommendation. If you're planning on substantial growth in the next 2-3 years you should consider doing the VM setup you proposed. Also, at this size I'd strongly consider a hosted solution for Exchange, unless you bought the licenses already.

Make sure you have backups - and not on that 3x3TB SATA array (see this for why: What counts as a 'large' raid 5 array? )

I really can't recommend getting a descent consultant to look at your situation enough. It sounds like you've already made some mistakes that cost hundreds in licensing, the last thing you need is for that to be a regular occurrence. It's apparent you aren't familiar with System Administration work.
