I was thinking that, too (and mentioned that in e-mail to the original poster). It does seem like a lot to ask to get a Sysplex Timer (or even two) at this point in time, with STP an option on the newer systems. It's hard to say exactly what the "best" option would be without knowing all the circumstances, but my hunch is that getting a larger system (probably a System z9 BC unless substantial growth is expected) and then relegating the z800 to cold or warm standby, ideally in another building, would be a nice mix of low cost combined with forward progress in improving business availability. It really depends on the service levels the original poster is trying to achieve, though. Sometimes the business always needed Parallel Sysplex and it's past time. Sometimes the growth means the business has reached a point where it's more important than before. "It depends." - - - - - Timothy F.
