C1000-038 IBM z14 Technical Sales Questions and Answers

Questions 4

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?

Options:

A.

Adding a third General Purpose processor and a zIIP is the only solution that will eliminate both problems.

B.

Adding a zIIP cannot be done because a 702 with two General Purpose CPs can only have two zIIP Processors.

C.

If there is a large amount of Java work, adding a zAAP would substantially reduce the zIIP utilization and free up the zIIPs to handle workloads that are specifically zIIP eligible.

D.

Turning on SMT, while providing more zIIP throughput, could affect the zIIP intensive workloads performance negatively.
