That's a REALLY SMALL box for that many OSes, and splitting it up into LPARs will just make it seem smaller. Run VM in basic mode on the box and make everything else a guest. > It'll have 4 NIC cards, one will be used for SE and LAN3274 consoles. > 3 will be available for IP and SNA (not sure if we'll have a > need to demo > SNA) > > Suggestions for design? Dedicate two of the adapters to Linux guests and use guest LANs to connect VM TCP and the z/OS systems. Use CTC interfaces in Linux guests to connect to the VSE and OS/390 systems. Keep the 3rd adapter in case you have to do SNA. > I was thinking of using z/VM and guest lans to establish connectivity > between the z/VM images and the z/OS images. > Then I'll need CTC's for the 2.10 & VSE LPARs right?

Not only is it The Right Thing To Do, it's a transparent setup for when you get a bigger box and can do the same thing on a box with real hipersockets. > Also, does it make sense to keep the z/OS and OS390 images in their > own LPARs versus under zVM ...I'm thinking YES... Not on a box that small, esp with only 1 real engine. An H70, you might consider LPARs, but not here. -- db
