Tom -
General numbers here, but our 449 MIP z9 2096-S02 IPLs in about 5 minutes
and the new z10 CBU machine we have at 26 mips, a 2098-A01 when its not
turned up, manages to still IPL the same processes in 15 minutes or so.
Hope that helps.
Say.. if you have a second... can you share where your data centers are?
I'm debating with management right now on the distance between our data
centers being too close and I'm collecting information from anyone I can
talk to about how far apart others have their's.
Thanks.

My management wants to benchmark the IPL process to see how long it will
take at various levels of MIPS, MSUs, or whatever measurement criteria
can be used. The purpose of this is to determine what the smallest z10
is we can contract for our DR site that will IPL in a reasonable time
frame. The plans are to contract for the smallest system possible with
the provisions of being able to bump it up during the few times each
year we do a full blown DR test or in the event the is an actual
disaster situation. So we might contract for a 2098-A03 and the bump it
all the way to a 2098-Z03 when needed.
Has anyone ever done something similar to this? Is there any way to set
a cap on the system that will take affect immediately and be active
during the IPL process? I know that the standard softcap won't work
since that doesn't take affect until the MSU four hour rolling average
hits the cap, which wouldn't happen during an IPL. What I know as a
"hard cap" involves restricting the LPAR to its weight, so I don't think
that would work either. Is there any other way to cap a system?
