100 mips isn't enough to run VM? My first systems programmer job in 1984 we had a 4331 running VM/SP 2 with VSE as a guest under it (which was where we moved all the applications from our old Univac machine.) It only had, I think, 0.4 mips. That's 400Kips, folks, and 4M of real memory. Worked fine until we also got 20 concurrent engineering types on 3178's doing interactive work, too. Then we had to upgrade to a 4361 with 8M of real storage.

I'm surprised that 100+mips isn't enough to run what I've laid out, given dynamically weighting for CP and dynamic storage reconfiguration. I agree that the flexibility of reconfiguration that VM gives you is a good reason to configure everything under VM. And...the learning experience of using guest lans and vctcs etc. will be valuable. I'm not up to speed on VM yet, so three followup questions: ---------------------------------------------------------------------------- -- ------- >I would try not to have all the guests running simultaneously if at all possible. 1. Will VM give me more flexibility when I carve up the real memory to the individual guests (vs multiple lpars using dynamic storage reconfiguration). Can I add/delete real memory to guests on the fly? 2. Same question for CP ? >Dedicate two of the adapters to Linux guests and use guest LANs to connect >VM TCP and the z/OS systems 3. Are these two Linux guests suggested for the purpose of routing(to the other guests) DMZ, firewall, etc. as you have mentioned in the past? Tia Dave
