Hi. trying to find references for running both AIX and IOS before we order P7 server to replace 2 separate servers. Anyone with any experience in this? Thank you!

There are plenty people doing this out there. We've been doing it since p5. Got any specific questions?

We have a few specific questions. We are trying to get a warm fuzzy about this, however sales reps so far have been unable to give us any references of other companies doing this. We will be moving from 2 I570's and P590 to a single P770. Are there any gotchas to watch out for in combining the 2 os’s under each server? Anything that may not work that we need to look out for? Are you happy with the move for your production systems?

there is no gotchas, servers 'll work fine dont worry. everything are same with other servers, what re u using for manage servers? IVM or HMC, i dont know IVM anyway, you will create new lpars before migrate old servers and you will choose os from HMC, (like attachment)

Thank you for the response - this makes us feel better. Hoping you may be able to answer a few more specific questions.
How are you setting up CPU and Memory pools for a mixed environment? Does it require separate pools or can a combined pool work?
Does dynamic memory allocation work with iSeries? How about active Memory Expansian?

i'm not using sharing cpu pool, if you can plan correctly desired resources;lpars not use over desired. You can enable uncap options of course, if lpar need more cpu, it can get from available CPUs.
pools, can use if you don't want any impact an lpar's cpu growing to another lpar, otherwise not need. You can use default pools. All resources on default pools at the first config.
yes dynamic cpu or memory increase or IO slots add/remove works for IBM I too, i'm not using AME bacause of there is results of this, u need sacrifice some cpu and response time when lpar need top memory. You can use AME just for create more lpar with lower memory. I not recommend for production servers.

Ok, thank you, that is good. So you are using a combined cpu pool for both I and AIX servers then? I'm going to enter another post with some other questions on different pieces - disk and NPIV - if you can help, thanks!
