I'm in the process of migrating my file server to Hyper-V VMs. Currently my OS (Windows 2012R2) is on a physical server with an iSCSI to a dedicated SAN volume of 700GB. What would be the best way to have this setup on Hyper-V? Is it best practice to have the System/OS VHDs partitions hosted in a separate volume from the data partition? Do I have create two volumes - 1 for OS and 1 for the 700GB data partition? How do I keep the data partition, should I use a dedicated SAN volume or do I create a 700GB fixed disk which then resides inside the SAN volume?
My Hyper-V Setup is DELL R720 with Windows 2012 R2 with DELL Equalogic 6210XV.
