I agree with Chris. In my (more limited) experience, if HP NonStops are
used they're mainly as front-end switches at card network member
banks. And their use in this niche role is fading, ...
I don't know the details, but I know our "Tandems" go into a "store
and forward" mode when anything on the mainframes slows down.
That could be a processor down, CICS regions down, transaction
failures, dasd contention, spin loops (Ok, that one hasn't happened
lately), etc. I don't see their value lessening even if their function
is needed less often.
In my experience, Tandems are not "switches". They process card traffic.
I'm aware of one migration from mainframe to Tandem.
Here in Poland, vast majority of ATMs and POS's are non-mainframe.
Even no mainframe "behind the Tandem".
Only 3 banks are using mainframes at all. Was 4. The fourth one decided
to drop the mainframe due to costs. The project was succesful - no entry
for re-boot hill. Oh, two big mainframe projects I'm aware exceeded
planned timeframe and budget.
Only one ATM network is using mainframe.
Did I mention the majority of HW elements used for sysplex can also be
used in "open" systems environment? I mean DASD, FC switches, tapes...
Disclaimer: I like mainframes, but I'm not blind.
