Hah no. When my company was looking to justify buying a new mainframe, they tried to leverage our server team by saying "You can run Linux in LPARs just like you do on VMware etc." So we met with the sales guys. They asked the size of our average Oracle VM (RAM mostly), and when they heard 256GB, they smiled. Then the mainframe manager asked how much it would cost to provision that much RAM for 10-12 LPARs. I wish I had taken a photo of his expression. Needless to say the meeting ended shortly after, and we didn't pursue spending almost 100x the amount we were spending on our ESX hosts...
- neverartful 6y agoWhile you can run Linux in their own LPARs, I think the much more common scenario is to run them as guests under z/VM. Why is this? Because a single LPAR typically represents a sizable chunk of the overall resources (and cost). On the other hand, you can create an LPAR for z/VM (say with 2-4 IFLs) and have those hardware resources spread out across many Linux z/VM guests.
- greedo 6y agoYou're still going to pay through the nose for 384GB of RAM (times ten VMs).
- neverartful 6y agoNo disagreement there.
