[Users] Fault tolerant storage

[Jakub Bittner]

Hi,

would it be possible in near future to use for example 2 attached DATA 
storage (iSCSi, or so) as fault tolerant storage?

I mean I have two data storage connected to data center and they include 
exactly same data and my VMs runs from one and all changes are mirrored 
to second like RAID 1 and if one storage fails everything switch to 
second storage without user notice?
