If I have 2 clusters in one data center each running different cpu types (amd/intel) can they both access the same shared storage domain(gluster in my case)?  

I'm not interested in live migration between the clusters really, though stopping and starting on another would be nice.  I've tried looking at various threads and list emails and I've found some mentions of it, but usually as an aside while discussing other matters so I could never quite say for certain it was working or not.
