A z14 ZR1 is configured for Capacity Marker W06 and 6 IFLs. At the time of purchase, the customer had not expected growth. Therefore, the CPC was configured as a Max12 (FC#0637). However, additional Java workload makes the deployment of a zIIP engine feasible.

What are the considerations, if any, that the customer has to include into their plans for upgrading?

A. Depending on the type of specially engine (IFL, ICF, zIIP, or SAP) the additional resource can be added concurrently to the existing CPC model.

B. None. The upgrade is done by changing the microcode and can be activated concurrently.

C. A change in the z14 ZR1 CPC drawer feature upgrade is disruptive. The additional engine will have an impact on the maintenance cost.
D. All IBM software contracts have to be checked and amended to include the new zIIP engine.
