Most SANs that I've seen aren't in "geographically separate"
locations in the way most think of this.  It's usually metronet --
it's not even a different city.  That's a poor disaster prevention
strategy, although it might be worth it as step one.  (If you can
take the latency, of course, you can make this go further, but true
both-coast solutions, for instance, will make the latency such that
users will certainly be able to see it.)
