Due to the so-called 'Technology Dividend', 100 z800 MSU = 90 z890
MSU = 81 z9BC MSU.
100/81 = 1.234567 (amazing number!)
So, expect your MSU-based software charges to go up by just over 23%
if you go back to the z800.
Bad assumption! You assumed that function cost=f(MSU) is linear. It's
not. Usually it's sublinear with positive value for f(0). (Forgive me
my "math English").
So, 23% MSU more could mean 10% fees more. And only for MSU-based
software - mostly IBM. Many companies do charge for MIPS or just
machine model (again MIPS, just to avoid "technology dividend" and
other possible tricks).
True. For most IBM software, the marginal per-MSU price gets a little
lower for each additional MSU you add.
My point was simply that an existing z9BC workload will require 23% more
MSU wen transferred to a similarly-configured z800.
