One of the dominant themes of the z13 processor announcements is that delivered capacity is becoming increasingly dependent on effective utilization of processor cache. Benefit from the experiences of a user; who initially experienced a capacity shortfall migrating from zEC12 to z13 models; but ultimately achieved significant capacity improvements through a series of configuration changes. This session will review metrics associated with changes including increasing the number of hardware CPs; LPAR topology; and maximizing the number of Vertical High CPs in the Hiperdispatch configuration. Various benefits of deploying "excess" hardware capacity will also be covered.-Todd J. Havekost-USAA
