With the advent of H-V verison 3 (2012) I think this quesion needs to be revisited. I was told long ago (about a year and a half :) ), that it was frowned upon to use an iSCSI connection from within a child VM. If the data was large (more than 2TB), then using a pass-though disk was perferred. You lost HA, live migraton, etc, but oh well. Now, things have definitely changed, but the matrix of determining the right answer is too much for me. So I ask the gods of all Microsoft Knowledge, what is the current state of this question? Can I (should I) use an iSCSI initiator in a VM to attach to iSCSI SAN storage? Should I just convert the disk to a vhdx and gain all things good and holy that the MS gods want me to realize with a virtual environment? Should I stick with pass-through because it still offers APPRECIABLY better performance (in my instance, I'm talking about file server storage, but we can assume for everyone's benefit that we might be talking about more robust performance needs)? What say you?
Thanks,
