A customer is running a Z14-702 with two zllPs. They started noticing that the zllP utilization during peak hours was averaging about 85% due to a new Java application. After examining RMF, they realized that during these periods, much zllP eligible work was overflowing to the general purpose CPs. causing them to also run over 90% for considerable periods of time.
They have a limited budget for new equipment. After reading about Simultaneous Multithreading (SMT), they think they can solve their problem by turning SMT on instead of purchasing either another GP, a zAAP, or a third zllP in order to get more through put.
What must they consider before making the decision to turn on SMT or purchasing another processor?
