Question
A customer is running a z14-702 with two zIIPs. They started noticing that the zIIP utilization during peak hours was averaging about 85% due to a new Java application. After examining RMF, they realized that during these periods, much zIIP 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 zIIP in order to get more throughput. What must they consider before making the decision to turn on SMT or purchasing another processor?
Options
- AAdding a third General Purpose processor and a zIIP is the only solution that will eliminate both
- BAdding a zIIP cannot be done because a 702 with two General Purpose CPs can only have two
- CIf there is a large amount of Java work, adding a zAAP would substantially reduce the zIIP
- DTurning on SMT, while providing more zIIP throughput, could affect the zIIP intensive workloads
