Lyn: I bow to your expertize and have not read your paper on the 3725. My sort of well lets say home grown experience with trial and error (sigh a lot of errorr). Gut instinct said the limiting factor was the byte channel (which I understood) was the vast majority of channel hook ups for the box. My experience later on on the 3745 was that it seemed to perform well as we really hit it with a *LOT* of data (we essentially ran shadow copy of our system out to NY from Chicago) through it everynight. We had one nasty bug that turned out to be non IBM related but that is a different issue. I do not think we really ever ran into a software issue on the PEP. I didn't want to run PEP but some of our customers sold the idea to my management over my strong objections. I wish MVS was as bug free as was PEP (at least for us). The thing just worked period. That is why I liked it so much.
