Pat Helland (formerly with Tandem and MS, now with Amazon) has written
some very lucid and entertaining discussions about how economics are
changing their system design points. He was one of the originators of
the Tandem Non-Stop transaction system and a life-long transaction
processing bigot. Now he's talking openly about his ACID apostasy. If
Pat is ready to cast that aside, I think everyone else ought to at least
take it seriously.
a lot of the ACID (and TPC) stuff originated with Jim. When Jim left
system/r group (original relational/sql implementation):

and went to tandem, we would frequently drop by and visit him. In fact,
I got blaimed for something called tandem memos ... couple posts with
minor refs:

Later when we were doing ha/cmp (on non-mainframe platform)
http://www.garlic.com/~lynn/subtopic.html#hacmp
and out preaching availability and scale-up on commodity priced hardware

Jim and I had some disagreements ... of course he was with DEC at the
time, and they were pitching vax/clusters.
Of course, later he was up on the stage announcing commodity priced
clusters for scale-up and availability.
for other drift ... a recent thread discussing some vax/vms and
mid-range mainframe market somewhat from late 70s through later 80s.
