IBM zEnterprise EC12 and IBM zEnterprise BC12 are the last z Systems servers to offer support for zAAP specialty engine processors.

Beginning with the IBM z13, only zIIP specialty engine processors will be supported and customers should plan to run zAAP-eligible on zIIP specialty engines.

This is intended to simplify planning and management efforts while allowing customers to maximize their use of specialty engines, which can help lower the cost of computing.

Customers on IBM zEnterprise servers or earlier may want to begin planning efforts to run their zAAP eligible workloads on zIIP engines, using zAAP on zIIP.
