VMs running from iSCSI

Hi.

I've been reading about Hyper-v on WS2012 and I have the following question.

Is it possible to have a WS2012 with Hyper-V role running virtual machines located on a iSCSI storage (eventually each VM on a dedicated LUN)? Any performance problems may occur?

I know that this scenario is often used with WS2012 clusters, but I'm asking just for curiosity.

BTW, if i use DPM 2012 SP1 to do backups of guest VMs, is it advisable to put all VM backups in the same iSCSI LUN?

Thanks.
