Well, the several examples I can think of moved the workload elsewhere,
presumably to x86. I hate to be negative about Linux on Z because I was at
Linuxcare for five years doing Linux deployment on Z and thought it was a
great platorm. But I fear that the hype was too great, such that folks
jumped in too deep and then said "Uhhhh". I'm really not sure.
I can remember the hype. IBM were making ludicrous claims about spinning
up 40k Linux VMs on z/VM. At the time most of the hype was centered
around x86 server consolidation. I can also remember reading an article
suggesting that Googles core systems could run on z :) All of that was
completely debunked when I attended a SHARE presentation about lessons
learned from migrating to Linux on Z. There were a good few battle
stories and it was refreshing to hear a real world experience. I think
the presenter was Mike Shorkend, who frequents this forum. IIRC, the
migration was successful but not without quite a few surprises. What
fascinated me the most was the work that went in to the TCO analysis.
I'm not sure IBM helped with the LinuxONE thing, because that made it seem
different, not "Just Linux, but with mainframe scaling etc."

<mailto:[email protected]> is alive and well-it's just not the
obvious growth area that it seemed like 15 years ago. Acourse I'm not what I
was 15 years ago either!
