My take is: i == integrated. just about everything is integrated with little difference. p == power - as in Power Architecture and "powerful" z == zero down time - the RAS on the z is unmatched. I've had a CP and an OSA fail and not even __notice__ it at the application or connection level. With the CP failure, a spare took over the load with no outage to the running application. With the OSA failure, the second OSA did an "arp takeover" and all the sessions continued with not a single session failure. The Windows people were stunned that the user's didn't even know that something had gone wrong. x == I have no idea. -- Q: What do theoretical physicists drink beer from? A: Ein Stein. Maranatha!
