This thread, as with many on this topic, starts out with the assumption that
UNIX, LINUX and Windows Server Operating Systems, along with server class
hardware are no different to the Home PC they loaded up with Windows XP in
order to play Warcraft, or the laptop they use for email and terminal
emulators. It only goes downhill from there.
It gets even more ridiculous when Linux is suddenly an anointed HA OS simply
because it will run on an IBM Mainframe, along with Solaris and pre-RISC
AIX. I have not figured that out yet.
As Radoslaw said, "I love Mainframes but I'm not blind." Those that wish to
make a valid comparison between z/OS and other HA OS need to get their noses
out of Windows and have a look at how HA is being done on other SERVER
Operating Systems. In many cases it is not platform that provides the HA,
but rather an application running on the OS like Veritas Cluster Server or
HACMP. These HA applications won't even run on XP.
And what I would give for backup software like Commvault or Netbackup on the
Mainframe. Backup on Open System Server software is Light years ahead of
anything on the MF, whether it's IBM or ISV software. It's like comparing a
Ferrari to the first stone wheel...
I like to take a wider view than the lint in my belly button...

The problem I'm having, then, Ron, is identifying exactly
where z/OS belongs today.
On the one hand I hear that nothing beats the MF for
reliability, security, recoverability, and so on. Then
I hear people telling me not be so sure about that. So
if these other platforms are up to MF levels, and they
are so much cheaper, why would anyone stay with a
mainframe today?
What's the driving factor that gives mainframes any
kind of real life expectancy, given that Windows and
xNIX are now up to MF standards?
