John:
For purposes of software licensing, IFLs and CPs are TWO
machines. Effectively adding a single IFL to either machine
creates a 3rd z9 with 1 IFL (again ONLY for software licensing).
If this was on the z9 EC the cost would be $22,500 OTC for the
base z/VM license (plus any features: Dirmaint, Perfkit, RACF,
RSCS) with the corresponding annual S&S charges. Note that this
is LIST pricing and IBM (and your business partner if applicable)
may offer special pricing for z/VM when purchased with an IFL on
a z9 BC.

Again, CPs and IFLs are treated as separate machines for software
licensing by every vendor I am aware of. You would only need to
license the Linux distro (and Oracle) on the single IFL.
