Hi David. Just as Alan Altmark points out, check the pricing model carefully first. We run z/VM in two separate LPARs only using IFLs, which seems to be the most cost-effective solution. It works very well, we are just a few persons managing nearly 200 zLinux servers here. Be prepared for the question: How much does a 4 core cpu with 24GB memory cost ? You will end up with the answer: It depends :-) And: You don't need 4 cores and you definitely not need 24GB, and anyhow you don't need to bother about these values because we will monitor and config it right for you. ( you might have to phrase it 'nicer' ) In this case don't forget to inform that because they probably need three machines the total cost for all three will be very cost comparative to an 'identical' x86 setup. They need Test,QA and Prod, and they should be identical. Here you will get the test and QA very cheap if you charge for usage, because they will often just idle.
This fact only will often make the z environment very cost effective compared to x86. If they also have critical applications they will need(should want!) duplicate prod servers with a load balancer in front. This makes the deal even better. And do not forget to tell them the delivery time! Hours or minutes, instead of weeks !

Please pardon the intrusion if I should be posting this someplace else. Our management is considering the acquisition of a new z114 "sandbox" system primarily for testing new hardware (DASD and tape). They would also like to conduct a z/Linux POC using the same machine. I know that z/Linux can run in native mode on a System z processor but I wasn't sure about it running side by side with z/OS. Can this be done using PR/SM and building separate LPARs on the z114 for running z/Linux and z/OS together on the same machine? I know that the most sensible solution would probably be to get a z/VM hypervisor and run z/OS and z/Linux as guest operating systems under it. However, there's a lot of resistance here to running yet another operating system such as z/VM. Any comments, advice, etc.?
