When talking about clustered SQL servers for serious use Oracle RAC
is only thing to come on my mind, and to begin with it you need shared
disk from SAN with clustering capable filesystem. One could argue
that having Oracle as storage instead of plain journaled cluster fs
adds cost and complexity for an unknown amount of performance ..
This new mailbox format is going to be on its best in very few and
special environments but in those it should be _much_ faster than
maildir and more flexible than mbox.
