When I was looking at the announcement letter for z/VM 5.4 I seem to remember something about (on a z10) being able to mix CP's and IFL's in the same LPAR and have z/VM dispatch LINUX machines on the IFL's.... Or maybe that was 'wishfull interpretation' on my part. Anyway (if true) I wonder if there is some type of new pricing to handle that senerio.

Is it better to use VM instead of LPAR? All comments appreciated. That's going to be determined by what you intend to run. z/VM, Linux, and a bunch of IBM middleware is licensed per-processor. If you create an LPAR with standard CPs in it (whether running z/VM or not), you'll be paying license charges for all the CPs in the CEC. If you create an LPAR with IFLs, you'll be paying license charges for all the IFLs in the CEC. The same will be true of z/VM. Most of the new workload being run on z/VM these days is Linux, so typically it makes sense to run z/VM and Linux on IFLs, to avoid having to pay for licenses on the standard CPs. If you add IFLs to handle more z/VM or Linux workload, that means you don't have to pay more for you z/OS license charges, whereas if you add standard CPs to handle more z/VM or Linux workload, your z/OS license charges will go up. Over and above that, if you think you might be running more than a small handful of systems, z/VM is by far the better way to go. It will save you tons of people time, and provide more manageability and flexibility. Mark Post
