I don't know that there's anything specifically comparing Linux on z/VM versus VMWare. VMWare is one of the virtualization tools IBM is recommending for their xSeries customers, so it has some merit to it. Perhaps your local zSeries sales rep will have some thoughts on why VMWare on Intel is not as good a choice as z/VM on zSeries hardware. :)
>From my perspective, VMWare is not nearly as mature a technology as z/VM. It doesn't have anywhere near the system management and Linux-enabling features that z/VM does. The Intel platform is not nearly as rock solid as zSeries. If you price a full-blown Intel system with redundant everything, etc., etc., you're getting up into the 10's of thousands of dollars, even up to $50K. It only takes a few of those to add up to one mainframe. They'll knock your socks off on CPU-intensive workloads, of course, but if you have a lot of mainframe-resident data that needs to be accessed, having a Linux system on the same box and using HiperSockets is a nice setup for a number of reasons. Take a browse through the news articles and press releases at http://linuxvm.org/Info/l390link.html to get a feel for why other people have made the move, and see if any of it applies to your circumstances.

I'm Hopeing someone here can point me to some good documents on the strengths against an intel platform running VMWARE. There have been Questions come up about performance, Oracle, How many guests can we put out there and what kind of performance loss per guest do we get or can we expect? Just want to justify in spending a quarter of a million on the hardware and be able to get what we need out of it. Does anyone know of some good docs pointing to these answered questions. -Cameron ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
