Let me see if I understand this correctly:
We currently do NOT run z/VM at all. We have a z9EC with two CPs and a
z9BC with four CPs. Each "box" also runs a Coupling Facility, but that
appears immaterial to this discussion. The two "boxes" are connected in
a parallel sysplex, with all non-CF LPARs running z/OS.
We are contemplating the purchase of one IFL (for now), to "test-drive"
running Linux on z. We currently "assume" that our cost to license z/VM
to run ONLY on the IFL (regardless on which "box") would be $22,500 plus
the "subscription" for one processor.
Is that assumption valid? (Was it ever valid?) Or would our cost for
z/VM be 3 * $22,500 plus 4 * $20,250 (plus "subscriptions"), based on
the IFL becoming the seventh "engine" in the enterprise, and despite
that z/VM would be run ONLY on the IFL ("dedicated" LPAR)?
How about the "subscriptions" for Linux itself (RHEL and SLES are the
two candidates), again to be run ONLY on the IFL? Same question for
Oracle, to run ONLY on the IFL.
