Before conducting extensive benchmarking, what’s needed is AN UNDERSTANDING OF RELATIVE MACHINE CAPACITY using commonly available design parameters.
obtain a more accurate and useful comparison of platforms, you must consider the weight of the workload (see Figure 2, page 46). If the workload is unable to exploit multithreading, the best capacity for machines comes from single threaded mode. With the exception of Power Systems Enterprise turbo max cache machines, the others show significantly higher raw core ratios as thread capacity gains in weight for max throughput. This means that except for very low-weight workloads, System z servers hold an advantage. BladeCenter* Extension (zBX). Because of this, the zEnterprise platform can be a robust solution for a variety of workload types. Examples are workloads that require

the integration of low-weight analytic or application-serving components with high-weight components such as existing z/OS* workload or other work that’s consolidated to create a highweight load running in a virtualized Linux* on System z environment. To illustrate this, Figure 3 (page 46) maps out the three IBM machines on a throughput versus capacity chart.

Joe Temple is an IBM Distinguished Engineer, Master Inventor and Senior Certified IT professional with more than 35 years at IBM.

Weighing the Platforms Workloads requiring sustained throughput without being gated by thread capacity through data sharing, resource sharing or a lack of parallelism in the code create a significant price and performance disadvantage for the System z socket. These low-weight workloads are the kind that leverage multithreading, which further compounds the disadvantage. If the scale required from each node is large enough, the advantage will go to Enterprise and PureSystems solutions. However, low-weight loads can often be partitioned onto relatively small nodes. At reasonable scale, they can be implemented well on the Intel or Power blades of a zEnterprise
