Hello v_user,

Here is a link to our deployment guide, and if you look on page22 it shows the best way to cable the system with your 3 servers & switch. http://downloads.dell.com/Manuals/Common/powervault-md3200i_Deployment%20Guide_en-us.pdf

Now once you get your MD3220i cabled base deployment done then you will use MDSM (Modular Disk Storage Manager) to manage the MD3220i. You find MDSM which is on the Resource CD. Here is a link to the resource cd just in case you need it. http://www.dell.com/support/home/us/en/04/Drivers/DriversDetails?driverId=JPKXM

So when you get MDSM installed and are going to setup your Disk groups that is where you will define that you will have a cluster for the virtual disk that you will create of 2TB & 3TB. Here is the link to the user’s guide for MDSM. http://downloads.dell.com/Manuals/Common/powervault-md3200_Administrator%20Guide_en-us.pdf

Please let us know if you have any other questions.
