I can't speak to z/OS software charges, but for VSE, we pay for only one license for multiple instances running under z/VM. And we pay the VSE license for the total capacity of the machine.
I don't think you can say that VM is better than LPAR as a general statement. In some cases VM definitely is better, and in others, LPAR is the winner. Do you need to create new z/OS instances on short notice for a brief testing period? z/VM is a clear winner. Do you need every last CPU cycle for your production z/OS? LPAR is better here. Do you need to frequently shift resources around between your LPARs? z/VM might make your life easier. Is your hardware environment fairly static? Could be better to stay with LPARs. Are you thinking of running Linux on your mainframe? You will almost certainly want to run z/VM then. z/VM brings you unmatched flexibility, but at a cost of some CPU cycles and money. If you have large numbers of LPARs though, it can reduce the complexity of your configuration, and allow better sharing of your resources. Perhaps if you expand on what you hope to achieve, we can provide more targeted responses. Peter -----Original Message----- From: The IBM z/VM Operating System [mailto:[EMAIL PROTECTED] On Behalf Of Ward, Mike S Sent: August 27, 2008 11:31 To: IBMVM@LISTSERV.UARK.EDU Subject: Lpar Vs VM Hello all, I have a question. When we set up and lpar with an operating environment such as MVS, we get software charges for both lpars from IBM. Third party vendors don't seem to care if it's on the same machine (Most don't) since they charge for the full mip rate of the machine regardless of whether it's utilized or not. Long ago, about 30 years I had a VM shop and we ran multiple instances of OS/VS1, MVS, etc, but were only charged for on license of software product. Is this still the case? Is it better to use VM instead of LPAR? All comments appreciated.
