>From a software pricing point of view separate LPARs are often cheaper. Some products are only needed in development (compilers, some development tools, some testing tools), most (if not all) products you need to license for production you'll also want to use on your test LPARs. (otherwise how would you test new releases and maintenance). For products that are licensed without sub-capacity, at the machine level, this does not matter (though you might have benefit isolating Testing to one of multiple machines).
It's possible, though in my experience with many shops, not too likely, that production LPARs and testing LPARs do not have their 'peak's at the same time. So that in general separate LPARs are better than combined LPARs. Of course, your mileage may vary. Al -- Al Sherkow, I/S Management Strategies, Ltd.
