I've been thinking about this and IF we do this, shouldn't we make sure 
all primary storages are supported?

I'm also looking for a valid reason for doing this. Why not expand your 
cluster size?

Wouldn't doing this break the whole idea of zones, pods and clusters? 
Since they all share the same resources you can have multiple clusters 
going down (or even your whole zone) by just one component failing.

I know this is the responsibility of the guy who builds the CloudStack 
cluster, but still, why have more clusters when they share the same 
primary storage? You just add one SPoF spread out over multiple clusters.
