My assessment of this, is that companies and government have spent so
much money on the frame itself, that they have no problem building very
expensive disk sub-systems as well. In the UN*X world, we aren't used to
spending that kind of money, and management isn't used to the price tag
over here either. We are starting to see mainframe customers move to
AIX/Solaris/Linux and they are willing to spend more money on disks.
They end up with some very high performance for their databases.
Sometimes they are beating what they saw on the mainframe.
