System resources

As with any application, resources are used by HCL Workload Automation for Z to accomplish the required work. This section introduces the key resources and discusses the performance ramifications of each related to an interactive workload in the HCL Workload Automation for Z product. The key resources are I/O time, processor, and storage.

There is a direct correlation between real storage availability, virtual storage availability, I/O activity, and processor utilization. A shortage of real or virtual storage causes an increase in I/O activity, which in turn causes an increase in processor utilization. So, a change to any one of these areas has some effect on the use of the other resources.
