Using vhd and passthrough disks on MD3200
I was wondering if anyone has experience with this type of setup. We have 3 virtual servers on our Dell 3200i using vhd's for the OS C drive and passthrough disks for the D data drives. Has anyone used this type of setup before or is there a better way to do this? We need to be able to map to the D drives of each virtual machine which is why we have the D drives as passthrough disks. Should the OS also be passthrough? Will there be a perfomance hit it this setup type? We wanted to keep the OS separate from the data partitions. Which is how they were prior to this.
Any insight is greatly appreciated.

Hello MLarouche,
First off with the setup that you have laid out that is supported by dell. Second I am not sure what os that you are using but by your description it appears that you are using Hyper-v & if you are that you maybe using 2008 R2 SP1 but not sure. One thing to know is that there is a documented 3% increase in using passthrough disk over vhd’s. & that comes from Microsoft itself. Also if using passthrough you need to confirm that the MD doesn’t have more than 64 connections per controller. If you go over the 64 connections per controller the MD won’t notice it but the VM will & then the VM will not be able to connect.
Let us know if have any other questions.

Thanks Sam
Just when I think I have included all the pertinent information I leave out the OS! You are correct we are using W2K8 R2. Thanks for the response, we are way under the 64 connections, I think my concern was more of using a C drive vhd that has a passthrough disk as a D drive attached to it. Both vhd file and passthoruhg are located on the MD3200i. But from your response I dont think it will cause any issues.
thanks again Sam
