Most installations tend to upgrade their CPCs to the equivalent model in the newer generation – for example, from a z13 710 to a z15 710. Accordingly, IBM’s capacity planning tools are designed to model upgrades to newer generations within the same speed range (7xx to 7xx, 5xx to 5xx, and so on).

There are numerous stories of customers moving to a lower speed range (z13 7xx to z15 6xx, for example) and finding that the performance exceeds their expectations.

But if the IBM tools are not intended to model such moves, how do you evaluate if such an upgrade would be right for your workloads?

In this session, Frank and Todd will discuss the attributes that they use to evaluate such upgrades.

Is a Sub-Capacity CPC the Right Move for You?
