Mark,
If you are running a coupling facility using ICMF on the Multiprise, be aware
that ICMF does not exist on any zSeries box. You will need an ICF engine to run
a coupling facility.
Nice to have as options, are IFL's, zIIP's, and zAAP's. You may never want or
need them, but they can be added.
Also nice to have, and probably easy to set up would be Server Time Protocol.
Your z9 can actually keep accurate time with only minor, as I understand it, set up.

Has anybody given much thought to the hidden benefits of migrating from a
MP3000 to a Z9 BC?
I currently have a one processor MP3000 7060-H30 that rarely needs more
than 40% of the MP3000 cpu capacity. The Z9 BC A01 configuration that I
am considering has only one CP, but it also has a SAP for I/O and QDIO for
TCPIP offload. Single TCB tasks like CICS are not an issue in our
environment, so I expect the Z9 A01 to meet our cpu capacity requirements.
Also, I will be moving to a DS6800 disk subsystem on FICON.
I expect the SAP, QDIO, and DS6800 will greatly improve my overall
throughput, but they are difficult to quantify.
I expect I/O and TCPIP traffic to fly through the system. And I expect
the MP3000 cycles that are used for I/O and TCPIP will now be available
for other tasks.
Have I missed anything obvious? Any other ideas?
Thanks,
Mark
