Are you able to set up async replication between the two SANs? You need to have a VPN link between two sites, preferably a redundant one, and with some serious bandwidth too, if you intend to replicate the SANs across it. Once you have a replica of your storage domain on the second site working, if the primary site goes down, you can bring everything up on the secondary site. If you want this at a VM and not SD level, you might either have to replicate LUNs separately and use direct LUNs for VMs, or write some management scripts around it, so you will never end up with the same VM started on both sites. The latter will also require active-active LUN replication, which is usually a bad idea to start with. load balancing will be very tricky, DR - much easier.
