Radek,
with every integrated solution you can say you can buy individual
things and put them together. Of course. It is the controlling logic
that makes it integrated, in this case zManager.
Power blades in zBX - I don't think there are other than IBM Power
blades, IBM decided to support one kind of blade in three (IIRC)
possible configurations. And if you use a supported blade, it will
work because it was tested. When you plug the blade, its firmware will
be customized so that zManager can talk to it. You can buy the blade
from IBM or from BP.
x86 blades - I admit I have not studied the announcement yet, I assume
there will be again some set of blades which are supported, presumably
IBM blades. I don't know if you can mix IBM/HP/Dell/etc blades in one
bladecenter anywhere (please correct me if I am wrong). So when you
get bladecenter from one vendor you use its blades there.
ISAOPT - again, customized firmware, customized OS with application.
For ISAOPT purposes you really want to have a full control over
hardware, firmware, OS and application, it is a black box, you want
everything to work as expected, without deviations. (BTW, in these
days I am at customer implementing ISAOPT).

All hw (z196, blades, switches, bladecenters) firmware is updated from
one place, so when there are new MCLs you get them from IBM, from one
place. How many times you had problems that some
servers/switches/whatever were on old firmware and it was recognized
only when problem occurred ? Many distributed people ignore firmware
updates.
