If you keep your exchange database in same virtual drive there is no issue. If your machine fail still you can recover your exchange database.<br />

Thank You for your input and the links. &nbsp;I guess I need to rephrase my question a little. &nbsp;With my 4 disks in a RAID 10 I will configure them as 2 virtual drives. &nbsp;As far as the Hyper-V host goes it will see virtual drives C and D. &nbsp;My question is, if I create a virtual instance of my exchange server (assuming it is created on host drive C) then I need to create a second virtual drive for the Exchange server to store the database but it needs to be located in the HOST drive D. &nbsp;This would allow the database to be stored on a separate spindle as Microsoft recommends.<br />
<br />
Here is the excerpt from the first link you provided:<br />

<blockquote>
Storage used by Exchange should be hosted in disk spindles that are separate from the storage that's hosting the guest virtual machine's operating system.
</blockquote>
<br />
Is my logic correct (especially about creating the exchange database drive on the host drive D) or is there a different way of looking at this that I have missed.

Thanks Simon,<br />
<br />
Do you really think it would be better to use Raid 1 vs. Raid 10?? &nbsp;<br />
<br />
One other consideration that I failed to mention. &nbsp;One of the software applications that we use is based off of an older Foxpro model. &nbsp;I need to store the data on a server share and a 'front end' is installed on each workstation. &nbsp;Given the above setup would you think it best to install it on the essentials instance on disk 1 or install yet another server 2012 instance on the second drive and have the share there. &nbsp;I know Foxpro is pretty disk intensive so not sure where the best would be. &nbsp;With the 4- 1 Terabyte drives I should have plenty of space with either Raid 1 or Raid 10 wherever just not sure of the disk access issues with exchange.<br />
I should note that my exchange usage is pretty light. &nbsp;10 total users (most using active sync with their phones also) with no more than 4 logged into the system at a time.<br />

It isn't space you are after.<br />
Two RAID 1 arrays gives you two separate disk systems, so you have better performance. <br />
For the FoxPro application, I can only suggest trying it on the Essentials system and see how it performs. <br />
<br />
Simon.

Exactly the concise answer I needed!

Exchange 2013 on Hyper-V HD Setup Question

Exchange is the server side of a collaborative application product that is part of the Microsoft Server infrastructure. Exchange's major features include email, calendaring, contacts and tasks, support for mobile and web-based access to information, and support for data storage.

Windows Server 2012 is the server version of Windows 8 and the successor to Windows Server 2008 R2. Windows Server 2012 is the first version of Windows Server to have no support for Itanium-based computers since Windows NT 4.0. Windows Server 2012, now in its second release (Windows Server 2012 Release 2) includes Foundation, Essentials, Standard and Datacenter, and does not support IA-32 or IA-64 processors.

Microsoft Virtual Server was a virtualization solution that facilitated the creation of virtual machines on the Windows XP, Windows Vista and Windows Server 2003 operating systems. Virtual machines are created and managed through a web-based interface that relies on Internet Information Services (IIS) or through a Windows client application tool called VMRCplus. Features included Linux guest operating system support, Virtual Disk Precompactor, symmetric multiprocessing (SMP), x64 host operating system support, the ability to mount virtual hard drives on the host machine and additional operating systems support, including Windows Vista, and a volume shadow copy writer.

Microsoft Virtual Server

Hyper-V is a native hypervisor; it can create virtual machines on x86-64 systems and supersedes Windows Virtual PC as the hardware virtualization component of the client editions of Windows NT. A server computer running Hyper-V can be configured to expose individual virtual machines to one or more networks. Hyper-V Server supports remote access via Remote Desktop Connection. Administration and configuration of the host OS and the guest virtual machines is generally done over the network.
