Mainframe customers have had a choice of processor speeds for years. As full-capacity engines have grown, more and more customers are finding that those full-capacity engines are not an ideal fit for them. For some customers the z16 A02 may even be preferable to an A01. What are the advantages to using sub-capacity engines? Does your LPAR configuration matter? What metrics should be examined to determine if a more/slower configuration is a good fit for your workload? Is it possible that this choice might impact your software bill? Come to this session with Scott Chapman to learn why more/slower CPUs may be a better fit for many environments and how to determine what workloads might be at risk for moving to slower CPUs.
