Server 2012 R2 Hardware Raid or Storage Spaces

Last Modified: 2016-12-08
We are migrating a SBS 2011 system to Server 2012 R2; we have about 800 GB of data; 15 users with 5 needing remote access.  We decided on a Dell T430 with 4 x 1TB SATA drives configured in RAID 1.

Having got to the nitty gritty of building the new server (2012 R2 with Hyper-V and 2 VMs – 1 DC and 1 exchange)  I have got myself into a debate on whether to use storage spaces or not.

So my questions is:  Do I

1)      break the Hardware RAID and set up mirrored storage space.

2)      do a partial break – keep 2 drives in hardware RAID 1 to hold the Hyper-V OS (+ OS’s for the DC and Exchange servers ?)  and configure the other 2 drives as Storage Space for data etc.

The install of Hyper-V uses a partition for the OS:  I have a concern that this partition would not be included in the storage space so would have issues if that drive fails.

3)      stick to the Hardware RAID (and don’t use storage spaces)
