WIN2012 and storage model with SAN/NAS

[mario]

Hello everybody,
I tested ProxMox more then 1 year at 2 nodes with DRBD.
Now is time to set production environment.
I have 3 nodes and SAN/NAS, I'm thinking about VM WIN2012 with qcow2 on NFS for easy snapshoting the system (I' thinking also about iSCSI+LVM and standard backup LVM) - what You advice?
But I also would like to config ekstra disks for this W2012.
How I should create this disk (connect iSCSI+LVM to PM and create disk; connect iSCSI LUN directly to PM; connect iSCSI LUN directly inside W2012 ...)?
Snapshots of extra disks will be made on SAN/NAS
I need some advice - best practis with SAN/NAS.
Thanks in advance!

Ok, now I know that when I have only 1Gb slots in servers better will be use iSCSI MPIO.
But what with extra disk for data in W2012 guest? - iSCSI directly in Proxmox or maybe atache LUN in W2012 through the same interfaces what iSCSI targets to Proxmox?
