The difference between what you get with DB2 V7 and SMF 101 vs DB2 V8 and 
PROJECTCPU might be interesting...

I believe the former would be from measuring the appropriate CPU for DDF 
and ESTIMATING from there - and might be detailed enough to tell you which 
applications. (I've not seen the output so I don't really know the level 
of detail.) The latter is the "if you deployed a zIIP this is what you 
stand to eat into" MEASUREMENT. Not "what you get" as a shortage of zIIP 
capacity when deployed at very least could cause PROJECTCPU to 
overestimate... PROJECTCPU didn't do a lousy job you just didn't ante up 
enough zIIP capacity.

Apparently - at Expo last week - there had been some bemusement that 
PROJECTCPU could only project based on EXISTING supported workloads. Well 
duh! Throw 100 MSU of fresh SAP R/3 onto the machine and PROJECTCPU ain't 
gonna project THAT. :-)

Cheers, Martin
