Do you have any experience with Linux and SAN? Is it possible to use a shared
storage for the mailspools? I did some research some time ago (+1y) and found 
it not so mature and went for NFS instead (not nice
but it works pretty good.) But I don't feel like it  will hold up for the 
load of the new system plus I have a mush larger budget this time.
