OS: SBS2011 Standard with POA;
Hardware: Dell 2950
SAS RAID1 (2x146Gb) visible to Host;
SAS RAID10 (4x1Tb) visible to HyperV Client (SBS2011 Standard)
After installing Host OS (Windows Server 2008R2 with HyperV Server Role only), created SBS2011 Standard VM on Host's C:\ drive.
From within SBS2011, created separate volumes on the RAID 10 (2Tb available) for Exchange/Sharepoint, SQL/WSUS, User Data.
The host OS takes up 20Gb on the Raid1 volume. The SBS2011 VHD is 69Gb and a related BIN file under the Virtual Machines directory is another 12Gb.
So on the RAID1 (146Gb) array, I'm using 20Gb+69Gb+12Gb =101Gb/146Gb. The SBS2011 box backs-up to external USB drive.
I now want to back-up the VM from the Host. I've read about the changes needed in KB958662. I intend to either add an additional USB drive for the Host level back-up or move the current USB drive away from the VM for the Host to use.
LOB system is running SQL Server on an old 2003 server. I want to replace this with the PAO as a 2nd VM, but am concerned there isn't enough space on the RAID1 host volume for a 2nd VM.
So my question is -- should I reconfigure and allow the host to see the RAID10 system and put one or both VM's on that array? Or just increase the drive capacity on the RAID1 host and install 2nd VM with SQL Server there? Priority concern is enable host level backup on both VM's.
