I concur with Larry. I have many copies of it running, and several customers with application replication products Mimix, iCluster, etc. Most of the application replication customers are having a very strong look at or converting to Power HA. Cost of maintenance and support are a huge factor in the decision and strongly in favor of IBM PowerHA.
As Larry indicated there are many ways to put PowerHA up and your situation is different from most others but I can tell you that once it's up and running it does its job well.
One caveat: Make sure you keep up with PTFs with PowerHA. It does seem to be more sensitive to PTFs that other products.

Subject: Re: PowerHA for System I
I have several customers running PowerHA on IBM i. I know Jim O has the same. We also think there should be more classes and tried to get IBM to let us take their classes but they wanted us (as sellers, installers and supporters no less) to pay full price + T&E. Instead we taught ourselves.
The product is VERY different from the software guys (Mimix etc) though I'm not going to say Better or Worse because it depends on your environment.
One of the best points about is that once it is set up you do *NOTHING* to get objects to replicate. Zip, Zero, Nadda. You create a new file, it's replicated. Data area? Got that, whatever is in the library, replicated.
Another benefit is no journal receivers to mess with. Spent three hours on the phone yesterday with a customer who's HA partition went down because it ran out of disk space due to Mimix Journal receiver management getting 'unhooked'. REMEMBER: You still DO want to journal with PowerHA. Remember the Journaling Rules: 1) ALWAYS JOURNAL. 2) If you don't want to journal see rule 1. But with PowerHA they are not used for replication so you can manage the receivers more easily.
PowerHA continues to get better as well. There are multiple ways to implement the thing and we have come up with a couple that IBM basically pointed at us and laughed about. Then some guys in Europe actually started doing it that way and suddenly 'It's Legit'!
Sometimes I think IBM doesn't take me seriously. :-)

Hi,
Can anyone tell me if you are currently using IBM’s PowerHA product
and if there are classes being offered on the product?
The one company I have found that does offer the class has canceled it
twice for low participation……..which makes me now wonder about the
product itself.
Thank you
