Do you have resources that provide info on companies using Linux on Z and the benefits of this verses commodity hardware? I used to work for a Mainframe ISV but the majority of our software ran on z/OS. I only saw customers using Linux on Z to begrudgingly run software that wouldn't efficiently run on z/OS, mainly Java applications when customers didn't want to deal with the complexity of specialty engines. I realize because our software focused on z/OS I had limited visibility into the full operations at our customers.
- froh 1y agothe advantage comes with the full package, operations and all. you don't have racks with blades but one box or two, that you upgrade every few years and other than that your hardware side is covered. rewiring networks, reattaching storage etc all remotely, CLI, and most importantly you only pay what you use. you need one guy or a consultancy for the initial etc up and for fancy Config changes but once it's essentially set up you simply have a large Linux data centre and do Linux stuff. oh and you can hot plug additional physical CPUs into a running VM and pull it out and reassign when it's not needed, likewise RAM. that's somewhat difficult with commodity hardware. and there _are_ companies that value this and choose Linux on Z as a pure Linux deployment. but you have a point. if nobody in the building knows this, nobody's gonna call IBM and ask for a quote. it's simply not on anybody's radar.
