Hello Bruce,

As we even have on sort-of-a solution for shared disk clusters (the 
Shared Disk Failover part), we should explain this term (as you already 
do there).

Clarifying that all other solutions are for shared nothing clusters 
makes sense, IMO. We don't necessarily need to go into shared memory and 
the confusion which shared everything introduced. OTOH, where else to 
enlighten people about that if not in such a documentation?

To answer your question: by explaining these terms, they are 
demystified. The users will understand the experts better and have some 
fundamental terms which they can base their discussion on. Of course 
it's questionable how far to go, and we are debating just that now, I think.

But I have no doubt in the OSS tradition of good documentation. Long 
live the saying 'RTFM'! :-)

Regards

Markus
