For those customers that are not running WebSphere on z/OS but entirely on
Linux for z/Series and need additional capacity to support WebSphere
related Java overhead that yes, over a 5 year recovery you win if you don't
have to pay z/VM IFL processor license charges and Novell/Redhat/your
service vendor processor license charges.
If you've managed to browbeat WebSphere into running on z/OS (Well OK,
WebSphere 5 was a bear I dunno about 6) then no I don't think its worth the
expense to shuffle the cards to move the workload. Just as a zAAP processor
helps in the z/OS land from having to pay every vendor you have more money
cuz WAS is being a glutton, to a lesser degree, it would help in the z/VM &
WebSphere on Linux world. Enough so to make it worth marketing? Dunno. It
could however make the decision to add processor capacity less painful than
adding IFL's and incurring higher z/VM and Linux vendor maintenance
charges. It would make the capacity cheaper to buy as a zAAP than as an IFL by
that amount. I don't know what the savings would be, but I would have
to think that it would reduce the 5 year cost of engines plus software license
charges over that of IFL's. The caveat of course is having enough JAVA
workload in the first place since a zaap under z/VM would serve the same
function - execute java code.

Do you really think that moving enough WebSphere workload from z/OS to Linux,
turning off a CP and turning on an IFL would be more expensive than
leaving things as they are? Somehow I doubt that, but I don't have any prices
to verify the gut feeling.
